3 Description

MSPM0G350x microcontrollers (MCUs) are part of the MSP highly integrated, ultra-low-power 32-bit MCU

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 MSPM0G350x 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. These MCUs 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 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 modes. These devices provide data integrity

and encryption peripherals (AES, CRC, TRNG) and enhanced communication interfaces (four UART, two I2C,

two SPI, CAN 2.0/FD).

The TI MSPM0 family of low-power MCUs consists of devices with varying degrees of analog and digital

integration allowing for customers find the MCU that meets their project's needs. The MSPM0 MCU platform

combines the Arm Cortex-M0+ platform with a holistic ultra-low-power system architecture, allowing system

designers to increase performance while reducing energy consumption.

MSPM0G350x MCUs are supported by an extensive hardware and software ecosystem with reference designs

and code examples to get the design started quickly. Development kits include a LaunchPad available for

purchase. TI also provides a free MSP Software Development Kit (SDK), which is available as a component of

Code Composer Studio™ IDE desktop and cloud version within the TI Resource Explorer. MSPM0 MCUs are

also supported by extensive online collateral, training with MSP Academy, and online support through the TI

E2E™ support forums.
