MSPM33C321ASPZR Overview

MSPM33C321ASPZR is the LQFP-100 (PZ, 16 mm x 16 mm) orderable of TI's MSPM33C321A, a 160 MHz Arm Cortex-M33 microcontroller with TrustZone, FPU and DSP extensions in TI's MSP general-purpose MCU line. The datasheet (SLASFB6A, revised September 2026) pairs 1 MB of dual-bank flash and 256 kB of SRAM, both with ECC, with two 9.4 Msps 12-bit ADCs, two CAN-FD interfaces and a hardware security block (AES256, SHA256, public key accelerator, TRNG). It runs from 1.71 V to 3.6 V over -40 °C to 125 °C. TI lists this orderable as Active; the other packages in the same datasheet are marked preview.

Key Features

  • 160 MHz Arm Cortex-M33 with TrustZone, FPU and DSP; 4 kB instruction cache
  • 1 MB dual-bank flash with ECC and 256 kB SRAM with ECC
  • Two simultaneous-sampling 9.4 Msps 12-bit ADCs, up to 36 external channels; two 8-bit DACs; two comparators
  • Two CAN interfaces supporting CAN 2.0A/B and CAN-FD; Quad SPI for external memory
  • AES256, SHA256, public key accelerator (ECC/RSA), TRNG and immutable root of trust
  • VBAT island with RTC and tamper detection inputs; up to 93 GPIOs
  • Run mode 211 µA/MHz (CoreMark), standby 8 µA, shutdown below 100 nA

Applications

  • Grid infrastructure and smart metering
  • Motor control and factory automation
  • Uninterruptible power supplies and inverters
  • Test and measurement, medical and healthcare
  • Communication modules and data center equipment
