Atmel has expanded its SAM G series of ARM Cortex-M4 based MCUs with the addition of the SAM G54 and SAM G55 devices, targeted at Internet of Things (IoT) applications requiring higher performance, lower power consumption and smaller form factors.
"Designers are looking for simple to use solutions with an edge to help bring their differentiated products faster to market for both wearables and sensor hub management," claimed Vince Murdica, senior director of Sensor Centric Systems.
Available in WLCSPs as small as 2.84 x 2.84mm, as well as in 64pin QFP and QFN, the parts run at clock rates up to 120MHz. Power consumption is said to be as low as 102µA/MHz in active mode. Each part has up to 512kbyte of flash and up to 160kbyte of SRAM.
Additionally, the G55 series enables designers to specify the amount of SRAM required in sleep mode to further improve power efficiency.
