Microchip Technology ATSAMD11 SMART ARM-Based Microcontrollers provide one full-speed crystal-less USB 2.0 device interface and up to three Serial Communication Modules (SERCOM) that each can be configured to act as a USART, UART, SPI, I2C up to 3.4MHz, SMBus, PMBus and LIN slave. The ATSAMD11 has up to 10-channel 350ksps 12-bit ADC with programmable gain and optional oversampling and decimation supporting up to 16-bit resolution. These microcontrollers have one 10-bit 350ksps DAC, two analog comparators with window mode, and Peripheral Touch Controller. The ATSAMD11 supports up to 72 buttons, sliders, wheels, and proximity sensing. Microchip Technology ATSAMD11 SMART ARM-Based Microcontrollers have a programmable Watchdog Timer, brown-out detector and power-on reset, and two-pin Serial Wire Debug (SWD) program and debug interface.
