50 MHz Cortex-M0 — what it buys you on a control BOM
50 MHz on a Cortex-M0 core handles a single-loop PID controller polling an I²C sensor while logging over UART. The 24 KB Flash holds a modest firmware image. The 4 KB RAM limits runtime data buffers to a few hundred bytes.
Serial interfaces and analog input
I²C, SPI, and UART/USART are all present. The 8-channel 10-bit ADC reads temperature, current-sense, or potentiometer feedback.
