Dual Arm Cortex-M33 microcontroller family targets industrial and consumer IoT applications with TrustZone security and a 150 MHz operating frequency. The device family integrates up to 2 MB dual-bank flash with ECC, up to 512 KB SRAM, a 256 KB ROM, and multiple memory-expansion interfaces including FlexSPI. Connectivity includes USB high-speed and full-speed controllers, CAN FD, Ethernet with QoS, SDIO, I3C, I2C, SPI, UART, SAI, and FlexIO. Analog and control resources include 16-bit ADCs up to 2 Msamples/s, comparators, DACs, op amps, FlexPWM, quadrature encoders, and capacitive touch support. The family operates from 1.71 V to 3.6 V across a -40 °C to 125 °C temperature range.
