Texas Instruments MSPM0G310x Mixed-Signal Microcontrollers (MCUs)

Texas Instrument MSPM0G310x Mixed-Signal Microcontrollers (MCUs) are part of the MSP highly-integrated, 32-bit ultra-low-power MCU family 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, operate with supply voltages ranging from 1.62V to 3.6V, and support extended temperature ranges from -40°C to 125°C.

The Texas Instruments MSPM0G310x devices provide up to 128KB of embedded flash program memory with a built-in error correction code (ECC). These have up to 32KB SRAM with a hardware parity option. These devices incorporate a 7-channel DMA, a memory protection unit, and various high-performance analog peripherals. These peripherals include two 12-bit 4MSPS ADCs, a configurable internal shared voltage reference, and one general-purpose amplifier. These devices also offer intelligent digital peripherals such as two 16-bit advanced control timers, five general-purpose timers (with one 16-bit general-purpose timer for QEI interface, two 16-bit general-purpose timers for STANDBY mode, and one 32-bit general-purpose timer), two windowed-watchdog timers, and one RTC with alarm and calendar mode. These devices provide data integrity, encryption peripherals (CRC, TRNG, AES), and enhanced communication interfaces (four UART, two I²C, two SPI, and CAN 2.0/FD).
