Atmel Expands Ultra-low power SAM G series

New SAM G54/55 deliver industry’s smallest form factor for Cortex-M4 MCUs with low power and high performance for IoT, Wearables, and Sensor Hub Management

 

The new award winning SAM G Cortex-M4-based MCUs will announce two new additions to the series, the SAM G54 and SAM G55. Targeting the rapidly emerging Internet of Things (IoT) market including wearables, sensor hub management, healthcare, gateways, bridges, and audio devices, the new products deliver the right feature mix of higher performance, ultra-low power, smaller form factors and more SRAM providing an optimized solution for battery-operated devices and any other application needing high processing power in a small footprint. The G54 and G55 include all the features of the current SAM G series including an Atmel | SMART ARM® Cortex™-M4 MCU + FPU (floating point unit), integrated sensor fusion algorithms, down to 2.84 x 2.84mm package, high-performance frequency of up to 120MHz, ultra-low power down to 102µA/MHz in active mode, and down to 5µs wake-up.

In order to maintain energy efficiency, many smart, connected devices use a sensor hub to aggregate and manage the sensors in the device, converting the information into usable data to improve power efficiency and performance. The new SAM G55 gives designers the option to determine how much SRAM they will require to retain in sleep mode in order to achieve lower and better power efficiency for their designs by utilizing SRAM power banking.
