ATSAMG54N19B-AU

The SMART SAM G54 is a series of Flash microcontrollers based on the high-performance 32-bit ARM Cortex -M4 RISC processor. They operate at a maximum speed of 96 MHz and feature up to 512 Kbytes of Flash and 96 Kbytes 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 realtime timer (RTT), one real-time clock (RTC) and one 8-channel 12-bit ADC. The | SMART SAM G54 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 predefined conditions. This feature, called SleepWalking, performs a partial asynchronous wake-up, thus allowing the processor to wake up only needed.
