Overview
MSPM0G3105SRHBR from Texas Instruments is a 32-bit Arm® Cortex®-M0+ microcontroller with CAN-FD interface, 32KB flash, 16KB SRAM, dual 12-bit 4Msps ADCs, and operation up to 80MHz at –40°C to 125°C. It integrates GPAMP, configurable VREF (1.4V/2.5V), TRNG, AES-128/256, and supports motor control, industrial inverters, and smart metering.
For engineers reviewing the MSPM0G3105SRHBR datasheet, MSPM0G3105SRHBR pinout, MSPM0G3105SRHBR application, or MSPM0G3105SRHBR equivalent, key selection criteria include CAN-FD compliance, 32-pin VQFN package with 5mm × 5mm footprint, 1.62–3.6V supply range, STANDBY mode current of 1.5µA, and dual ADC channel count (11 external inputs).
Technical Context
The MSPM0G3105SRHBR implements an Arm Cortex-M0+ core with MPU and operates at up to 80MHz via PLL or internal SYSOSC (±1.2% accuracy). Its analog subsystem includes two simultaneous-sampling 12-bit ADCs with hardware averaging enabling 14-bit effective resolution at 250ksps, plus one GPAMP and shared internal VREF.
Digital peripherals include a 7-channel DMA, two advanced timers with dead-band and fault handling, five general-purpose timers (including QEI-capable and STANDBY-aware variants), two WWDTs, RTC with calendar, four UARTs (one supporting LIN/IrDA/DALI), two I²C (FM+, 1Mbit/s), two SPI (up to 32Mbits/s), and one CAN-FD controller compliant with ISO 11898-1:2015.
