Atmel has beefed up its sensor hub offerings for wearable devices with SAM D20 Cortex M0+ microcontroller core to add more functionality and further lower the power bar for battery-operated devices. The SAM D20 MCUs offer ultra-low power through a patented power-saving technique called “Event System” that allows peripherals to communicate directly with each other without involving the CPU.

Atmel is part of the group of chipmakers that use low-power MCUs for sensor management as opposed to incorporating low-power core within the application processor. According to market research firm IHS Technology, Atmel is the leading sensor hub device supplier with 32 percent market share.

Sensor hubs are semiconductor devices that carry out sensor processing tasks — like sensor fusion and sensor calibration — through an array of software algorithms and subsequently transform sensor data into app-ready information for smartphones, tablets and wearable devices. Sensor hubs combine inputs from multiple sensors and sensor types including motion sensors — such as accelerometers, magnetometers and gyroscopes — and environmental sensors that provide light level, color, temperature, pressure, humidity, and many other inputs.

Atmel has supplied MCU-centric sensor hub solutions for a number of smartphones. Take China’s fourth largest smartphone maker, Coolpad, which has been using Atmel’s low-power MCU to offload sensor management tasks from handset’s main processor. However, while still busy in supplying sensor hub chips for smartphones and tablets, Atmel is looking at the next sensor-laden frontier: wearable devices.

Wearable devices are becoming the epitome of always-on sensor systems as they mirror and enhance cool smartphone apps like location and transport, activity and gesture monitoring, and voice command operation in far more portable manner. At the same time, however, always-on sensor ecosystem within connected wearables requires sensor hubs to interpret and combine multiple types of sensing—motion, sound and face—to enable context, motion and gesture solutions for devices like smartwatch.

Sensor hubs within wearable environment should be able to manage robust context awareness, motion detection, and gesture recognition demands. Wearable application developers are going to write all kinds of apps such as tap-to-walk and optical gesture. And, for sensor hubs, that means a lot more processing work and a requirement for greater accuracy.

So, the low-power demand is crucial in wearable devices given that sensor hubs would have to process a lot more sensor data at a lot lower power budget compared to smartphones and tablets. That’s why Atmel is pushing the power envelope for connected wearables through SAM D20 Cortex M0+ cores that offload the application processor from sensor-related tasks.

The SAM D20 devices have two software-selectable sleep modes: idle and standby. In idle mode, the CPU is stopped while all other functions can be kept running. In standby mode, all clocks and functions are stopped except those selected to continue running.

Moreover, SAM D20 microcontroller supports SleepWalking, a feature that allows the peripheral to wake up from sleep based on predefined conditions. It allows the CPU to wake up only when needed — for instance, when a threshold is crossed or a result is ready.

The SAM D20 Cortex M0+ core offers the peripheral flexibility through a serial communication module (SERCOM) that is fully software-configurable to handle I2C, USART/UART and SPI communications. Furthermore, it offers memory densities ranging from 16KB to 256KB to give designers the option to determine how much memory they will require in sleep mode to achieve better power efficiency.

Atmel’s sensor hub solutions support Android and Windows operating systems as well as real-time operating system (RTOS) software. The San Jose–based chipmaker has also partnered with sensor fusion software and application providers including Hillcrest Labs and Sensor Platforms. In fact, Hillcrest is providing sensor hub software for China’s Coolpad, which is using Atmel’s low-power MCU for sensor data management.

The company has also signed partnership deals with major sensor manufacturers — including Bosch, Intersil, Kionix, Memsic and Sensirion — to streamline and accelerate design process for OEMs and ensure quick and seamless product integration.

More specifically, Hillcrest’s Freespace software will run on Atmel’s low-power microcontroller (MCU) solutions to provide high performance sensor fusion, gesture recognition and always on context awareness capabilities – with dramatically lower power consumption and extended battery life.

“Coolpad realizes that sensors are critical to differentiate its functionality and maintain its dramatic growth in the global smartphone market,” said Chad Lucien, Senior Vice President of Sales and Marketing at Hillcrest Labs. “We’re proud to have been selected by Coolpad to provide the sensor hub functionality that will define its new mobile experience and enable context awareness, augmented reality, improved navigation and better gaming.”

As we’ve previously discussed on Bits & Pieces, sensor hubs are a separate class of chips designed to offload sensor management from the main processor for mobile phones and other devices. Essentially, they reduce the power requirements to add always on sensing in smartphones, tablets and wearables devices such as activity monitors, smartwatches, as well as head mounted displays (HMDs).

This enables gesture control, context awareness, pedestrian navigation, augmented reality, health and fitness monitoring, along with immersive gaming. Hillcrest’s sensor hub software products combine an array of sophisticated algorithms to provide low power, high performance sensor fusion and transform sensor data into valuable application-ready information.
