Microchip Technology ATSAMD10 SMART ARM-Based Microcontrollers

Microchip Technology ATSAMD10 SMART ARM-Based Microcontrollers provide up to three Serial Communication Modules (SERCOM) that can be configured as a USART, UART, SPI, I²C up to 3.4MHz, SMBus, PMBus, and LIN slave. The ATSAMD10 has up to 10-channel 350ksps, 12-bit ADC with programmable gain, and optional oversampling and decimation supporting up to 16-bit resolution. They also feature one 10-bit 350ksps DAC, two analog comparators with window mode, Peripheral Touch Controller supporting up to 72 buttons, sliders, wheels, and proximity sensing. The ATSAMD10 has a programmable Watchdog Timer, brown-out detector, power-on reset, and two-pin Serial Wire Debug (SWD) program and debug interface.
