50 MHz Cortex-M3 — processing headroom for control and comms
The ARM Cortex-M3 core runs at 50 MHz, delivering enough throughput for real-time control loops, protocol parsing (UART, SPI, SSI, IrDA), and moderate data processing without external memory.
The 57 I/O lines, 3x10-bit ADC channels, and built-in brown-out detect, POR, PWM, and WDT peripherals reduce external component count.
