The is a SMART SAM G53 series 32-bit Flash Microcontroller based on the high-performance ARM Cortex-M4 RISC processor with floating point unit FPU. It operates at a maximum speed of 48MHz and feature 512kB of flash and 96kB of SRAM. The peripheral set includes one USART, two UARTs, three I²C-bus interfaces TWI, up to two SPIs, two three-channel general-purpose 16-bit timers, two I²S controllers with two-way, one-channel pulse density modulation, one real-time timer RTT and one 8-channel 12-bit ADC. The SMART SAM G53 devices have two software-selectable low-power modes, sleep and wait. In sleep mode, the processor is stopped while all other functions can be kept running. In wait mode, all clocks and functions are stopped but some peripherals can be configured to wake up the system based on events, including partial asynchronous wake-up SleepWalking™.
