2.3.3 MSPM0G3507-Q1

The MSPM0G3507-Q1 is an AEC-Q100 compliant automotive-grade MCU powered by an 80MHz 32-bit Arm® Cortex®-M0+ core with MPU, boasting 128KB ECC flash and 32KB parity SRAM for reliable performance, and it meets ISO 26262 ASIL B functional safety standards with dual windowed watchdogs, comprehensive fault detection and TÜV certification. It integrates high-performance analog peripherals including two 4Msps 12-bit SAR ADCs, zero-drift chopper op-amps, a 12-bit 1Msps DAC, configurable VREF and high-speed comparators, plus programmable analog routing for flexible mixed-signal design. For digital and connectivity needs, it offers rich interfaces like CAN FD, LIN/IrDA/DALI-enabled UARTs, I2Cs and SPIs, along with 22 PWM channels with dead-time control, QEI/general-purpose timers, a trigonometric math accelerator, 128/256-bit AES encryption with TRNG and a 7-channel DMA controller for efficient control and secure communication. Operating over -40°C to 125°C with a 1.62V-3.6V supply voltage, it features ultra-low power modes and up to 60 5V-tolerant GPIOs in compact packages, ideal for space-constrained automotive safety-critical and mixed-signal applications.
