Abstract

The MSPM33C321A-Q1 microcontroller from Texas Instruments delivers a high-performance automotive MCU product for current vehicle designs and electrified automotive systems. This automotive microcontroller supports AEC-Q100 Grade-1 requirements with included features like a 160MHz Arm® Cortex®-M33 CPU with DSP, FPU, and Arm® TrustZone® security, plus 1MB dual-bank flash and 256KB SRAM. Key automotive applications include advanced motor control (up to four DC motors or two BLDC motors), body electronics, adaptive lighting systems, instrument clusters, and other vehicle systems. The device provides 30 PWM channels, dual 12-bit ADCs (9.4Msps), and dual CAN-FD interfaces for comprehensive automotive connectivity. The ASIL B functional safety compliant features and hardware security with EVITA-light cybersecurity help meet modern automotive security requirements. The integrated security features include cryptographic accelerators (AES-256, SHA-256), an immutable root-of-trust, and secure firmware update. AUTOSAR® MCAL drivers and pin-to-pin compatibility throughout the MSP family of MCUs enable scalable automotive platforms. This next-generation automotive MCU addresses vehicle software advancements, secure design, and connected car technologies while targeting cost efficiency for automotive OEMs and their suppliers.
