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®
- Down to 100 µA/MHz in active
- Below 7 µA in deep sleep with SRAM retention
- Down to 3 µs wake-up from deep sleep to executing the first instruction in active mode
- Increased throughput
- Cortex-M4
- FPU
- Small package
- 3x3 mm w/ 0.4mm pitch
- WLCSP 7x7 pins
- Pin compatible across the family in WLCSP
