SAM G5x Series ARM® Cortex®-M4 Microcontrollers

Microchip's SAM G5x series, ARM Cortex-M4 microcontrollers redefine power and performance in Cortex-M4-based MCUs

Image of Atmel's SAM G5x Series ARM Cortex-M4 MicrocontrollersMicrochip's Atmel SMART SAM G family is optimized for ultra-low power and high-performance applications. Its small form factor is based on an ARM Cortex-M4 core and bundled with a floating-point unit (FPU). These devices offer unrivaled efficiency in a tiny 3 mm x 3 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.
