The MSPM0G150x microcontrollers (MCUs) are part of the highly-integrated, ultra-low-power, 32-bit MCU family from mixed-signal processing (MSP) based on the enhanced Arm® Cortex®-M0+ 32-bit core platform operating at up to 80MHz 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 1.62V to 3.6V. The MSPM0G150x devices provide up to 128KB embedded Flash program memory with built-in error correction code (ECC) and up to 32KB SRAM with hardware parity option. The devices also incorporate a memory protection unit, seven-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 1MSPS DAC, three high-speed comparators with built-in reference digital-to-analog converters (DACs), two zero-drift, zero-crossover op amps with programmable gain, and one general-purpose amplifier. These devices also offer intelligent digital peripherals such as three 16-bit advanced control timers, three 16-bit general purpose timers, one 24-bit high-resolution timer, two windowed-watchdog timers, and one RTC with alarm and calendar mode. These devices provide data integrity and encryption peripherals and enhanced communication interfaces (four UARTs, two I2Cs, two serial-peripheral interfaces (SPIs)).
