It runs at 80 MHz and carries 1 MB of Flash and 128 KB of SRAM, with a supply range of 1.71 V to 3.6 V.
The 80 MHz Cortex-M4 core with FPU handles single-cycle DSP and floating-point math, which matters for sensor fusion or motor-control loops that would otherwise burden a Cortex-M0+ or M3. The 1 MB Flash gives headroom for a full RTOS stack plus application code, reducing the need for external serial Flash in many designs. The 128 KB SRAM is enough for moderate data buffers and stack; if your application runs heavy graphics or large audio buffers, you may need to budget for external PSRAM or SDRAM. The peripheral set includes CAN, USB OTG, multiple SPI/I²C/UART, QSPI, and an LCD controller, which covers most industrial and IoT connectivity needs without external transceivers or bridge chips. The 12-bit ADC with 16 channels and dual 12-bit DAC handle analog front-end tasks on-chip.
