It features six highly flexible SERCOM modules that can each be independently configured as USART, SPI, or I2C interfaces. The 12-bit ADC supports hardware oversampling to achieve up to 16-bit equivalent resolution, while the 10-bit DAC at 350ksps enables analog output generation. The capacitive touch controller supports up to 256 channels for sophisticated user interfaces. The event system allows peripherals to interact without CPU intervention, reducing latency and power consumption.","working_principle":"The ATSAMD20J18A-AUT is based on the Arm Cortex-M0+ core with a two-stage pipeline optimized for low power and high code density. The six SERCOM (Serial Communication) modules are each independently configurable as USART, SPI, or I2C, providing maximum flexibility for communication-intensive applications. The 12-bit ADC with differential inputs and programmable gain stage uses hardware oversampling and decimation to extend effective resolution. The event system provides eight channels for inter-peripheral communication without CPU involvement, enabling low-latency response to external events. The DFLL48M and FDPLL96M clock generators provide flexible clocking options. SleepWalking allows peripherals to operate in low-power modes.","pin_description":"
