The MSPM0 family is the latest MSP system-on-chip (SoC) devices, that provides highly-integrated, ultra-low-power 32-bit MCUs based on Arm® Cortex®-M0+ 32-bit core platform. 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. In the latest MSPM0 family, there are two series of devices: MSPM0G operates at up to 80-MHz frequency, and MSPM0L operates at up to 32-MHz frequency.

Both MSPM0L and MSPM0G devices provide a variety of analog features to support different system designs. MSPM0L devices offers a 12-bit 1.45-Msps ADC with configurable internal voltage reference, one dual-mode (fast mode and ultra-low-power mode) comparator with built-in reference DAC, two zero-drift zero-crossover operational amplifiers with programmable gain, one general-purpose amplifier, and an on-chip temperature sensor. MSPM0G devices offer high-performance analog peripherals such as two 12-bit 4-Msps ADCs, configurable internal shared voltage reference, one 12-bit 1-Msps DAC, three dual-mode (fast mode and ultra-low-power mode) comparators with built-in reference DACs, two zero-drift zero-crossover and rail-to-rail op-amps with programmable gain up to 32x, and one general-purpose rail-to-rail amplifier. #GUID-20221214-SR0T-Z22P-VB64-TSFGZFPZVHSR/GUID-2D01CA4A-F465-4120-9F31-20B4B0241685 lists the analog features.

The MSPM0 ADC provides best-in-class ENOB and SNR performance of any ADC in its MCU class. The ADC provides 12-bit 4-Msps sampling and 14-bit 250-ksps averaged sampling on MSPM0G devices and 12-bit 1.45-Msps sampling on MSPM0L devices. The hardware averaging feature is able to increase the effective resolution of the ADC without the need for software and CPU intervention. The ADC also operates at these high speeds in low-power modes with fast wakeup times. The ADC signals that can be sampled directly from onboard OPA, DACs, temperature sensors, and up to 16 external input channels. The reference voltage can be connected to VDD, an external reference, or internal references. Configurable 12-, 10-, and 8-bit resolutions also support faster sampling rates. #FIG_PRZ_FJP_VVB shows the key attributes of the MSPM0 ADC.
