The ATSAM4N8CA-AU is a SMART SAM4N series 32-bit Flash Microcontroller based on the high-performance ARM Cortex-M4 RISC processor. It operates at a maximum speed of 100MHz and features 512kB of flash memory and 64kB of SRAM. Peripherals include seven USARTs, four SPIs and three I²Cs for fast serial communication, as well as a 16-channel 12-bit ADC, a 10-bit DAC, PWM, timers and RTC. The device operates from 1.62 to 3.6V. It is a medium range general purpose microcontroller with the best ratio in terms of reduced power consumption, processing power and peripheral set.
