Mixed-signal Arm Cortex-M33 microcontroller runs at up to 180 MHz and integrates up to 1024 KB Flash with ECC and 256 KB SRAM. The device includes four 16-bit ADCs, one 12-bit DAC, three high-speed comparators, four op amps, FlexCAN FD, LPUART, LPI2C and LPSPI interfaces. It operates from a 1.71 V to 3.6 V supply across a -40 °C to 125 °C ambient temperature range. The PN suffix indicates a WFBGA169 package for the 1024 KB Flash, mixed-signal MCX A346 configuration.
