SAM G MCUs

Redefining Power and Performance in Cortex®-M4 based MCUs

SAM G family is optimized for ultra-low-power and high-performance applications. Its small form factor is based on an ARM® Cortex®-M4F core and, bundled with a floating point unit (FPU), these devices offer unrivaled efficiency in a tiny 3x3 mm, 49-ball WLCSP package. The SAM G family is optimized with a highly-efficient set of serial peripherals including a 12-bit ADC, DMA, and a good SRAM-to-flash ratio. SAM G devices are ideal for sensor hub and battery-operated consumer applications.

The SAM G family comes in four series, the SAM G51, SAM G53, SAM G54 and SAM G55. These devices are fully compatible, even down to the WLCSP package.

Key Features:

picoPower^®
