Connectivity covers I²C, SPI, and UART/USART — enough for a Modbus RTU slave, an I²C sensor bus, or SPI flash logging. An internal oscillator is included, so no external crystal is required for many applications, though you can still feed an external clock if tighter timing is needed.
The ARM Cortex-M0 core runs at 50 MHz. That clock rate determines the maximum timer resolution and ADC conversion speed for your application.
