ARM Cortex-M4-based ultra-low power MCUs target sensor hub applications

January 09, 2014 // By Paul Buckley
Atmel Corporation has introduced the Atmel SAM G family of ARM Cortex-M4-based MCUs that integrate high performance and ultra-low power in a small form factor.

The complete solution is ideal for sensor hub and battery-operated consumer applications including sensor hubs for smartphones, tablets and Ultrabooks as well as wearables, healthcare, gateways, bridges and audio devices.

In the Internet of Things (IoT) there is demand for MCUs with ultra-small form factors, rich features, high performance, and lower power. Atmel's new SAM G51 and SAM G53 series meet all these requirements with 3x3 mm packaging, high-performance frequency at 48 MHz, ultra-low power consumption down to 100 µA/MHz in active mode, 7 µA in sleep with SRAM retention and down to 3 µs wake-up time. The new MCUs also have an option for a floating point unit (FPU) for applications requiring more computational power and precise calculations such as digital smart watches, wearables and mobile sensor hubs.

The new SAM G family offers an ultra-low power, high performance sensor hub solution, expanding the company's current portfolio of sensor hub options. Atmel has also added two new sensor partners including Cywee and AKM to its program to offer a complete system solution running on the Atmel platform.

To accelerate the design, a SAM G53 Xplained Pro evaluation kit is available for the SAM G53 families. The ATSAMG53-XPRO evaluation board includes an embedded debugger, Atmel Studio 6 integrated development platform and the Atmel Software Framework. The kit is also fully supported by third party partners IAR and Keil.


Atmel's new SAM G family of devices is available now.
