Atmel’s second 2015 FAE training comes to an end

Taking a look back at the final FAE training of the year… 

We couldn’t have found a more appropriate, well-suited place to host our final internal three-day technical training of 2015 than Shenzhen, China. The city is constantly innovating, with IoT startups popping up on seemingly each street corner, throughout every tech shop, factory and Makerspace. This is a good context to present product updates, show off design tricks and run workshops from early morning to late night. We also network with old friends and make new ones, which further strengthens the teamwork, extends our knowledge base and builds confidence to help our customers bring their ideas to life.

H2-2016-FAE-Training

The buzz of the week was the highly-anticipated, full-day workshop on our uber mini Bluetooth Low Energy chipset (the BTLC1000) with overviews of the supported protocol stacks, silicon and software architecture, introduction from product marketing, as well as a hands-on session using Atmel’s standard Xplained development boards, the recently-launched Atmel Studio 7 and Atmel START.

At Atmel, we spread our love equally between wireless and low power. The world’s lowest power 32-bit MCU, the SAM L21, even saw the birth of a new sibling: the SAM L22. This particular board is feature-compatible with the SAM L21, but comes with an LCD controller and some nifty power-save features.

When it comes to IoT applications, performance plays an integral role so we spent time on the new low-power modes and security capabilities of the SAMA5D2. FAEs in a hurry could also complete the entire workshop and connect the SAMA5D2 to a cloud with the WILC1000 Wi-Fi module.

To top off the event, we saw the debut of more wireless technologies with a complete 6LoWPAN stack emphasising security and authentication with Atmel’s wide range of CryptoAuthentication engines.

Still wondering if IoT is a big thing at Atmel? Well, duh! Between low-power MCUs, all major wireless connectivity protocols, security layers and a cloud ecosystem in place, we’ve got each of the necessary pillars covered.

Big thanks to Atmel’s training team, distributors, and of course, FAEs for making this event such a great success! Until next time!

The SAM L22 is a Cortex-M0+ MCU with a segment LCD controller

The Atmel | SMART SAM L22 delivers down to 39uA/MHz running CoreMark and features a segment LCD controller, peripheral touch controller and tamper detection. 

Atmel has expanded its popular lineup of secure, ARM Cortex M0+-based MCUs with the new SAM L22 series. The Atmel | SMART SAM L family is the highest scoring product family in the EEMBC ULPBench and offers an ultra-low power capacitive touch with a segment LCD controller that can deliver up to 320 segments, making the devices ideal for low-power applications such as thermostats, electric/gas/water meters, home control, medical and access systems.

The Internet of Things is driving connectivity in various battery-powered devices making security and ultra-low power critical features in these devices. With this in mind, the SAM L22 series boasts 256-bit AES encryption, cyclic redundancy check (CRC), a true random number generator, Flash protection and tamper detection to ensure information is securely stored, delivered and accessible. To get the lowest possible power consumption, the devices use Atmel’s proprietary picoPower technologies and smart low-power peripherals that work independently of the CPU in sleep modes. The latest MCU can run down to 39µA/MHz in active mode, consuming only 490nA with RTC in backup-mode.

“As more devices in the consumer, industrial and home automation segments are becoming smarter and connected, these devices require a number of unique features including ultra-low power, security, touch capability with an LCD — all features that are currently provided in the SAM L22,” explained Oyvind Strom, Atmel Senior Director of MCUs. “Atmel is already engaged with a number of alpha customers developing metering, thermostat and industrial automation solutions based on the new Atmel | SMART SAM L22 series.”

In addition to segment LCD supporting up to eight communication lines, capacitive touch sensing and built-in security measures, the SAM L22 includes up to 256KB of Flash and 32KB of SRAM, crystal-less USB device, programmable Serial Communication modules (SERCOM) and Atmel’s patented Event System and Sleepwalking technologies.

Those wishing to accelerate their designs will be happy to learn that the new SAM L22 Atmel Xplained Pro is now available. This professional evaluation board with an on-board debugger and standardized extension connectors is also fully supported by Atmel Studio. While the Atmel SAM L22 series is currently sampling, production release is slated for December 2015.
