Mixed-signal 32-bit microcontroller integrates an Arm Cortex-M33 core running up to 180 MHz with FPU, DSP extensions, MPU, and no TrustZone. The device provides 512 KB flash, 128 KB SRAM, 55 GPIOs, and a 64-pin LQFP package for compact embedded control designs. It operates from a 1.71 V to 3.6 V supply over a -40 °C to 125 °C ambient temperature range. Integrated peripherals include 4 LPI2C, 2 LPSPI, 6 LPUART, 1 CAN FD, four 16-bit ADCs, one 12-bit DAC, comparators, op amps, motor-control PWM, timers, DMA, and security-monitoring features.
