Why connect to the cloud with the Atmel | SMART SAM W25?


The “thing” of IoT does not have to necessarily be tiny. 


The Atmel | SMART SAM W25 is, in fact, a module — a “SmartConnect Module.” As far as I am concerned, I like SmartConnect designation and I think it could be used to describe any IoT edge device. The device is “smart” as it includes a processing unit, which in this case is an ARM Cortex-M0-based SAMD21G, and “connect” reminds the Internet part of the IoT definition. Meanwhile, the ATWINC1500 SoC supports Wi-Fi 802.11 b/g/n allowing seamless connection to the cloud.

What should we expect from an IoT edge device? It should be characterized by both low cost and power! This IoT system is probably implemented multiple times, either in a factory (industrial) or in a house (home automation), and the cost should be as low as possible to enable large dissemination. I don’t know the SAMD21G ASP, but I notice that it’s based on the smallest MCU core of the ARM Cortex-M family, so the cost should be minimal (my guess). Atmel claims the W25 module to be “fully-integrated single-source MCU + IEEE 802.11 b/g/n Wi-Fi solution providing battery powered endpoints lasting years”… sounds like ultra low-power, doesn’t it?

Atmel claims the W25 module to be “Fully-integrated single-source MCU + IEEE 802.11 b/g/n Wi-Fi solution providing battery powered endpoints lasting years”…sounds like being ultra low-power, isn’t it

The “thing” of IoT does not necessarily have to be tiny. We can see in the above example that interconnected things within the industrial world can be as large as these wind turbines (courtesy of GE). To maximize efficiency in power generation and distribution, the company has connected these edge devices to the cloud where the software analytics allow wind farm operators to optimize the performance of the turbines, based on environmental conditions. According with GE, “Raising the turbines’ efficiency can increase the wind farm’s annual energy output by up to 5%, which translates in a 20% increase in profitability.” Wind turbines are good for the planet as they allow avoiding burning fossil energy. IoT devices implementation allows wind farm operators to increase their profitability and to build sustainable business. In the end, thanks to Industrial Internet of Thing (IIoT), we all benefit from less air pollution and more affordable power!

ATSAMW25 Block-DiagramThe ATWINC1500 is a low-power Systems-on-Chip (SoC) that brings Wi-Fi connectivity to any embedded design. In the example above, this SoC is part of a certified module, the ATSAMW25, for embedded designers seeking to integrate Wi-Fi into their system. If we look at the key features list:

  • IEEE 802.11 b/g/n (1×1) for up to 72 Mbps
  • Integrated PA and T/R switch
  • Superior sensitivity and range via advanced PHY signal processing
  • Wi-Fi Direct, station mode and Soft-AP support
  • Supports IEEE 802.11 WEP, WPA
  • On-chip memory management engine to reduce host load
  • 4MB internal Flash memory with OTA firmware upgrade
  • SPI, UART and I2C as host interfaces
  • TCP/IP protocol stack (client/server) sockets applications
  • Network protocols (DHCP/DNS), including secure TLS stack
  • WSC (wireless simple configuration WPS)
  • Can operate completely host-less in most applications

We can notice that host interfaces allow direct connection to device I/Os and sensors through SPI, UART, I2C and ADC interfaces and can also operate completely host-less. A costly device is then removed from the BOM which can enable economic feasibility for an IoT, or IIoT edge device.

The low-power Wi-Fi certified module is currently employed in industrial systems supporting applications, such as transportation, aviation, healthcare, energy or lighting, as well as in IoT areas like home appliances and consumer electronics. For all these use cases, certification is a must-have feature, but low-cost and ultra-low power are the economic and technical enablers.

10 (+1) invaluable steps to launching your next IoT product


Let’s transition your products from a ‘dumb’ to ‘smart’ thing.


Many enterprises, startups and organizations have already been exposed to the innovation land grab stemming from the rapidly evolving Internet of Things (IoT). What’s available in the product/market fit arena? This is the hunt to cease some segment of the multi-trillion dollar growth reported to gain from the IoT, enabling embedded system connectivity coupled with the ecosystem value-add of a product or service. Even for that matter, transforming a mere idea that centers around connectivity solutions can present an array of challenges, particularly when one seeks to bring to market disruptive ways for the end-user to adopt from the more traditional way of doing things (e.g. GoPro, PebbleWatch, FitBit, and even to as far as e-health monitors, tire subscriptions, self-driving vehicles, smart bracelets, connected medical apparatus or Industrial Internet devices, home automation systems and more).

All together, there’s one overlaying theme to these Internet-enabled products. They are all pervasively SMART technologies that help monetize the IoT. Now, let’s get your products to transition from a once ordinary, mundane object to a much smarter, more secure “thing.” When doing so, this too can often present a few obstacles for designers, especially as it requires a unique set of skills needed to interface systems with connectivity to the cloud or Internet.

To top it all off, there may already be various product lines in existence that have a mandate to leverage a connected ecosystem/design. In fact, even new ones require connectivity to the cloud, having designs set forth to enhance via customer usage then combining this user data with other associated data points. Already, the development to enable such devices require an assortment of skills. It’s an undertaking, one in which requires knowledge and expertise to command stable connectivity in the infrastructure and design a product with security, scalability, and low power.

Moving ahead, here are some recommendations developers and Makers should know:

  1. Identify a need and market: The value of the smart device lies in in the service that it brings to the customer. Identify the need to develop a strong offer that brings value or enhances efficiency rather than creating a simple gadget. (See Marc Andreesen’s infamous blog on product/market fit for more tips).
  1. Validate your ideation: Carry out market research. Do your due diligence. Determine whether the device you think of creating already exists. Can improvements be ascertained with testimonial as an enhanced or unique experience? Indeed, benchmarking will allow you to discover any competitors, find sources of inspiration, develop a network of ideas to pool and find other areas for improvement as well.
  1. Prototype toward MVP: New device fabrication techniques, such as 3D printing, are the ideal creative validation for producing prototypes much faster and for less money. They also promote iteration, which is an integral process when designing the device towards MVP.
  1. Connect the ‘thing’ then concert it into a smart ‘thing:’ Right now, there is no mandatory standard for interconnecting different devices. Selecting the right technology is essential, particularly if the device requires low-power (speaking of low-power….) and event and state controls, which highly optimize extended power and the services to enrich the information system and eventally enhance user experience with a roadmap toward an ecosystem.
  1. Develop the application: Today, the primary smart devices are linked to an dedicated mobile app. Since the app transforms the smartphone into a remote control, it must be be easy to use for your end-users, and more importantly, simply upgraded via the cloud.
  1. Manage the data: Fitted with a multitude of sensors, connected gadgets generate an enormous amount of data that need to be processed and stored with the utmost security across all layers even to as far as using cryptography in memory. (After all, you don’t want your design become a ‘Tales from the Crypt-O” horror story.) 
  1. Analyze and exploit the data: By processing and analyzing the data, a company can extract the necessary information to deploy the right service in the right place at the right time.
  1. Measure the impact of the smart device: Set up probes to monitor your devices and data traffic quality. Answer questions objectively as to how it would securely scale and evolve should there be an instant high volume success and usage. This will help you measure the impact of the smart device in real time and adapt its actions accordingly, and model into the product roadmap and MVP spec.
  1. Iterate to fine-tune the device’s use: After launching the project, the process has only begun. Feedback needs to be taken into account in order to adjust and fine-tune the project. Due to its very nature, digital technology requires continuous adaptation and iteration. “Try and learn” and present riskier ideas to products are the fundamental principles behind transformation when imposing a new use.
  1. Prototype again: Continuous adaptation and iteration means that your company needs to produce a new prototype.
Here’s 10 + 1 invaluable Step to Launching Your IoT Project or Products

Here’s 10 + 1 invaluable steps to launching your IoT project or product.

11. Take advantage of the hands-on training in your region.

As an application space, IoT sensor nodes are enabled by a number of fundamental technologies, namely a low-power MCU, some form of wireless communication and strong security. With this in mind, the newly revealed Atmel IoT Secure Hello World series will offer attendees hands-on training, introducing them to some of the core technologies making the Internet of Things possible, including Wi-Fi and CryptoAuthentication.

What’s more, these sessions will showcase Atmel’s diverse Wi-Fi capabilities and CryptoAuthentication hardware key storage in the context of the simplest possible use cases. This includes learning how to send temperature information to any mobile device via a wireless network and how to enable the remote control of LEDs on a SAM D21 Xplained Pro board over a Wi-Fi network using a WINC1500. In addition, attendees will explore authentication of IoT nodes, as well as how to implement a secure communications link — something that will surely come in handy when preparing to launch your next smart product.

As you can see, so far, everyone is LOVING the Hello World sessions — from hardcore embedded engineers to hobbyists. Here some recent social activity following the recent Tech on Tour events in both Manchester and Heathrow, UK. Need we say more? These tweets say a thousand words!

4 reasons why Atmel is ready to ride the IoT wave


The IoT recipe comprises of three key technology components: Sensing, computing and communications.


In 2014, a Goldman Sachs’ report took many people by surprise when it picked Atmel Corporation as the company best positioned to take advantage of the rising Internet of Things (IoT) tsunami. At the same time, the report omitted tech industry giants like Apple and Google from the list of companies that could make a significant impact on the rapidly expanding IoT business. So what makes Atmel so special in the IoT arena?

The San Jose, California–based chipmaker has been proactively building its ‘SMART’ brand of 32-bit ARM-based microcontrollers that boasts an end-to-end design platform for connected devices in the IoT realm. The company with two decades of experience in the MCU business was among the first to license ARM’s low-power processors for IoT chips that target smart home, industrial automation, wearable electronics and more.

Atmel and IoT (Internet of Things)

Goldman Sachs named Atmel a leader in the Internet of Things (IoT) market.

Goldman Sachs named Atmel a leader in the Internet of Things (IoT) market

A closer look at the IoT ingredients and Atmel’s product portfolio shows why Goldman Sachs called Atmel a leader in the IoT space. For starters, Atmel is among the handful of chipmakers that cover all the bases in IoT hardware value chain: MCUs, sensors and wireless connectivity.

1. A Complete IoT Recipe

The IoT recipe comprises of three key technology components: Sensing, computing and communications. Atmel offers sensor products and is a market leader in MCU-centric sensor fusion solutions than encompass context awareness, embedded vision, biometric recognition, etc.

For computation—handling tasks related to signal processing, bit manipulation, encryption, etc.—the chipmaker from Silicon Valley has been offering a diverse array of ARM-based microcontrollers for connected devices in the IoT space.

Atmel-IoT-Low-Power-wearable

Atmel has reaffirmed its IoT commitment through a number of acquisitions.

Finally, for wireless connectivity, Atmel has cobbled a broad portfolio made up of low-power Wi-Fi, Bluetooth and Zigbee radio technologies. Atmel’s $140 million acquisition of Newport Media in 2014 was a bid to accelerate the development of low-power Wi-Fi and Bluetooth chips for IoT applications. Moreover, Atmel could use Newport’s product expertise in Wi-Fi communications for TV tuners to make TV an integral part of the smart home solutions.

Furthermore, communications across the Internet depends on the TCP/IP stack, which is a 32-bit protocol for transmitting packets on the Internet. Atmel’s microcontrollers are based on 32-bit ARM cores and are well suited for TCP/IP-centric Internet communications fabric.

2. Low Power Leadership

In February 2014, Atmel announced the entry-level ARM Cortex M0+-based microcontrollers for the IoT market. The SAM D series of low-power MCUs—comprising of D21, D10 and D11 versions—featured Atmel’s signature high-end features like peripheral touch controller, USB interface and SERCOM module. The connected peripherals work flawlessly with Cortex M0+ CPU through the Event System that allows system developers to chain events in software and use an event to trigger a peripheral without CPU involvement.

According to Andreas Eieland, Director of Product Marketing for Atmel’s MCU Business Unit, the IoT design is largely about three things: Battery life, cost and ease-of-use. The SAM D microcontrollers aim to bring the ease-of-use and price-to-performance ratio to the IoT products like smartwatches where energy efficiency is crucial. Atmel’s SAM D family of microcontrollers was steadily building a case for IoT market when the company’s SAM L21 microcontroller rocked the semiconductor industry in March 2015 by claiming the leadership in low-power Cortex-M IoT design.

Atmel’s SAM L21 became the lowest power ARM Cortex-M microcontroller when it topped the EEMBC benchmark measurements. It’s plausible that another MCU maker takes over the EEMBC benchmarks in the coming months. However, according to Atmel’s Eieland, what’s important is the range of power-saving options that an MCU can bring to product developers.

“There are many avenues to go down on the low path, but they are getting complex,” Eieland added. He quoted features like multiple clock domains, event management system and sleepwalking that provide additional levels of configurability for IoT product developers. Such a set of low-power technologies that evolves in successive MCU families can provide product developers with a common platform and a control on their initiatives to lower power consumption.

3. Coping with Digital Insecurity

In the IoT environment, multiple device types communicate with each other over a multitude of wireless interfaces like Wi-Fi and Bluetooth Low Energy. And IoT product developers are largely on their own when it comes to securing the system. The IoT security is a new domain with few standards and IoT product developers heavily rely on the security expertise of chip suppliers.

Atmel offers embedded security solutions for IoT designs.

Atmel, with many years of experience in crypto hardware and Trusted Platform Modules, is among the first to offer specialized security hardware for the IoT market. It has recently shipped a crypto authentication device that has integrated the Elliptic Curve Diffie-Hellman (ECDH) security protocol. Atmel’s ATECC508A chip provides confidentiality, data integrity and authentication in systems with MCUs or MPUs running encryption/decryption algorithms like AES in software.

4. Power of the Platform

The popularity of 8-bit AVR microcontrollers is a testament to the power of the platform; once you learn to work on one MCU, you can work on any of the AVR family microcontrollers. And same goes for Atmel’s Smart family of microcontrollers aimed for the IoT market. While ARM shows a similarity among its processors, Atmel exhibits the same trait in the use of its peripherals.

Low-power SAM L21 builds on features of SAM D MCUs.

A design engineer can conveniently work on Cortex-M3 and Cortex -M0+ processor after having learned the instruction set for Cortex-M4. Likewise, Atmel’s set of peripherals for low-power IoT applications complements the ARM core benefits. Atmel’s standard features like sleep modes, sleepwalking and event system are optimized for ultra-low-power use, and they can extend IoT battery lifetime from years to decades.

Atmel, a semiconductor outfit once focused on memory and standard products, began its transformation toward becoming an MCU company about eight years ago. That’s when it also started to build a broad portfolio of wireless connectivity solutions. In retrospect, those were all the right moves. Fast forward to 2015, Atmel seems ready to ride on the market wave created by the IoT technology juggernaut.

How Big Bang Theory and IoT relate to Tech on Tour


Hands-on ‘IoT Secure Hello World’ training introduces Atmel Wi-Fi and CrytoAuthentication technologies.


How The Big Bang Theory Relates to the Internet of Things

How many of you out there are fans of the CBS hit sitcom series Big Bang Theory? If you recall an episode from the show’s first season, entitled “The Cooper-Hofstadter Polarization,” the team of Sheldon Cooper, Leonard Hofstadter, Howard Wolowitz and Raj Koothrappali successfully triggered a lamp over the Internet using an X-10 system.

In order to accomplish this feat, the gang sent signals across the web and around the world from their apartment to connect not only their lights, but other electronics like their stereo and remote control cars as well.

“Gentlemen, I am now about to send a signal from this laptop through our local ISP racing down fiber optic cable at the of light to San Francisco bouncing off a satellite in geosynchronous orbit to Lisbon, Portugal, where the data packets will be handed off to submerged transatlantic cables terminating in Halifax, Nova Scotia and transferred across the continent via microwave relays back to our ISP and the external receiver attached to this…lamp,”  Wolowitz excitedly prefaced.

800px-X10_1

The funny thing is, the technology that the group of sitcom scientists was simulating could have just as easily been done using a Wi-Fi network controller like the WINC1500. However, at the time of airing back in March of 2008, open access for Internet users looking to control “things” around the house was seemingly something only engineers and super geeks thought possible.

We can imagine this is probably how it would’ve gone down…

Bringing Next-Generation Technology to You

In order to make the scene above possible, an Atmel | SMART SAM D21 was hooked up to the WINC1500 and connected to a solid-state relay, thereby enabling the team to control the lamp.

If this captivated your attention, then you’re in for a treat. That’s because Atmel is taking its “IoT Secure Hello World” Tech on Tour seminar on the road — starting with Europe!

As an application space, IoT sensor nodes are enabled by a number of fundamental technologies, namely a low-power MCU, some form of wireless communication and strong security. With this in mind, the Atmel IoT Secure Hello World series will offer attendees hands-on training, introducing them to some of the core technologies making the Internet of Things possible, including Wi-Fi and CryptoAuthentication.

These training sessions will showcase Atmel’s Wi-Fi capability and CryptoAuthentication hardware key storage in the context of the simplest possible use-case in order to focus attention on the practical aspects of combining the associated supporting devices and software. This includes learning how to send temperature information to any mobile device via a wireless network and how to enable the remote control of LEDs on a SAM D21 Xplained Pro board over a Wi-Fi network using a WINC1500. In addition, attendees will explore authentication of IoT nodes, as well as how to implement a secure communications link.

Take the very fundamental use-case of switching on an LED, for instance, which will represent our ‘Hello World!’ For this IoT application, the LED will be controlled using a smartphone app via the Internet, while a sensor node will be enabled to read an analog temperature sensor. The first part of the training will introduce Atmel Wi-Fi technology, which connects our embedded development kit of choice, an Atmel | SMART SAMD21 Xplained Pro, via the Atmel SmartConnect WINC1500 Wi-Fi module to a local access point. The result will be the ability to easily and securely send temperature information to any mobile device on the network, while also having remote control of the LED.

From the moment a ‘thing’ is connected, it becomes susceptible to a slew of potential security risks from hackers. That’s why the second part of the training will delve deeper into how CryptoAuthentication can be used to authenticate the temperature sensor node and host application before it can read the temperature information to avoid fake nodes. A secure communications link will be implemented using a session key to and from the remote node.

When all is said and done, building for the IoT demands innovative and secure solutions while architecting a balance between performance, scalability, compatibility, security, flexibility and energy efficiency — all of which Atmel covers extremely well.

Exploring Atmel’s new microcontrollers, IoT and wearables

More and more companies, regardless of their vertical, are trying to get closer to their customers and see various aspects of the internet of things (IoT) as the way to do so. For a good example, here is Salesforce Wear Developer Pack which, as they say:

..is a collection of open-source starter apps that let you quickly design and build wearable apps that connect to the Salesforce1 Platform. Millions of wearable devices connected to the cloud will create amazing new application opportunities.

Since Salesforce.com cuts across all industries this has potential impact in many different market segments.

And, the wearable devices that they list are Google Glass, Android Wear, Samsung Gear Watch, Myo Armband, Nymi Bionym, Pebble Watch, Jawbone UP, Epson Moverio, Vuzix Smart Glasses, Oculus Rift, Meta Glasses.

This combination brings home that the internet of things isn’t just about the things, it is about connecting the things back to the cloud so that the data generated can be aggregated where it has much greater value.

I am sure that people will design SoCs for various aspects of IoT, but even if they do I think it will be in old processes, not even 28nm, so they can integrate sensors and analog and wireless on the same chip. But more likely a lot of these will be small boards with microcontrollers, wireless and sensors on different chips. For example, take a look at the iFixit teardown of the Fitbit, which in its current incarnation is about one inch by quarter of an inch.

atm1

An important aspect of doing this sort of design is having enough microcontrollers with the right combination of features. You can’t afford to have twice as much flash as you need or too many unused functions. The Atmel microcontroller product finder shows that at present they have 506 different ones to choose from.

The most recent two are SAMA5D4, and SAMD21 which are specifically targeted towards wearables and IoT projects. These are the latest two products in the Atmel SAM D family.

One area of especial concern in this market is security since it is too dangerous to simply try and do everything in software on the microcontroller. Keys can be stolen. Software can be compromised if it is in external RAM. An area of particular security concern is to make sure that any JTAG debug port is secure or it can be used to compromise almost anything on the chip.

So what are these chips?

The SAMA5D4 is an ARM Cortex-A5 device with a 720p hardware video decoder. It has high security with on-the-fly capability to run encrypted code straight out of external memory, tamper detection, secret key storage in hardware, hardware private and public key cryptography and ARM TrustZone. It supports both 16 and 32 bit memory interfaces for maximum flexibility. It is targeted at applications that require displays, such as home and industrial automation, vending machines, elevator displays with ads, or surveillance camera playback.

The SAMD21 is the latest Atmel microcontroller based on the ARM Cortex-M0+ but in addition to the features on earlier cores it also has:

  • Full speed USB device and embedded host
  • DMA
  • Enhanced timer/counters for high end PWM in Lighting and motor control – I2S
  • Increased I2C speed to 3.4Mbit/S
  • Fractional PLL for audio streaming

As you can deduce from the feature set it is target at medium end industrial and consumer applications, possibly involving audio and high power management.

And, to show that this sort of market is starting to become real, at the salesforce Dreamforce event earlier in the week a keynote was given by will.i.am of the Black Eyed Peas (and a founder of Beats that Apple recently acquired). In a chat with Marc Benoiff, CEO of Salesforce.com, he has already leaked that he will introduced a wearable wrist computer that doesn’t require a phone to piggy-back on (unlike the Apple Watch).

Watch the chat:
