MSPM0G150x microcontrollers (MCUs) are part of the highly-integrated, ultra-low-power 32-bit MCU mixed signal processor (MSP) family based on the enhanced Arm® Cortex®-M0+ 32-bit core platform operating at up to 80-MHz frequency. These cost-optimized MCUs offer high-performance analog peripheral integration, support extended temperature ranges from –40°C to 125°C, and operate with supply voltages ranging from 1.62 V to 3.6 V.

The MSPM0G150x devices provide up to 128KB embedded Flash program memory with built-in error correction code (ECC) and up to 32KB SRAM with a hardware parity option. The devices also incorporate a memory protection unit, 7-channel DMA, math accelerator, and a variety of high-performance analog peripherals such as two 12-bit 4-MSPS ADCs, configurable internal shared voltage reference, one 12-bit 1-MSPS DAC, three high-speed comparators with built-in reference DACs, two zero-drift, zero-crossover op amps with programmable gain, and one general-purpose amplifier. These integrated analog peripherals and processing capabilities can greatly reduce form factor and allow the MSPM0G150x series to be a great option for implementing the motor control algorithm with Hall-effect position sensor measurement and for performing low-side current sensing.
