SAM G MCUs Based on Arm® Cortex®-M4F Core
The 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 3 × 3 mm, 49-ball WLCSP package. The SAM G family is optimized with a highly efficient set of serial peripherals including a 12-bit Analog-to-Digital Converter (ADC), Direct Memory Access (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.

Microchip Bootloaders
Bootloaders are used to upgrade firmware on a target device without using an external programmer or debugger. Commonly used with microcontrollers (MCUs), a bootloader contains code that loads and executes an application program. Bootloaders can also perform additional tasks such as validating the code integrity and authenticity.
