64 MHz Cortex-M0+ — what the core clock buys you
It carries 128 KB of Flash and 36 KB of SRAM, which together give enough room for a modest real-time control stack plus a communication protocol layer. The 30 I/O lines in the 32-UFQFN package keep the board area tight for space-constrained designs like sensor nodes or motor-control interfaces.
Brown-out detect and POR are integrated, so the reset supervisor on the BOM can often be dropped.
Analog peripherals and connectivity
Thirteen 12-bit ADC channels and two 12-bit DAC channels handle multi-sensor acquisition and analog output without external converters. The connectivity set — I²C, SPI, UART/USART with LIN and IrDA, plus USB and HDMI-CEC — covers the common industrial and consumer bus requirements.
No last-time-buy window to track, no end-of-life clock running.
