3 Description

MSPM0H321x microcontrollers (MCUs) are part of the MSP highly-integrated 5V power supply and 32-bit

MCU family based on the enhanced Arm® Cortex®-M0+ core platform operating at up to 32MHz 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 from 4.5V.

The MSPM0H321x devices provide up to 64KB embedded flash program memory with 8KB SRAM. These

MCUs incorporate a high-speed on-chip oscillator with an accuracy up to ±1.2%, eliminating the need for

an external crystal. Additional features include a 3-channel DMA, CRC-16 accelerator, and a variety of highperformance

analog peripherals such as one 12-bit 1.6Msps ADC with VDD as the voltage reference, and an

on-chip temperature sensor. These devices offer intelligent digital peripherals such as one 16-bit advanced

timer, four 16-bit general purpose timer, one windowed watchdog timer, one independent watchdog timer, and

a real-time clock (RTC). These devices also offer a variety of communication peripherals including three UART,

one SPI, and two I2C. These communication peripherals offer protocol support for LIN, IrDA, DALI, Manchester,

smart card, SMBus, and PMBus.

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

integration enabling customers to find the MCU that meets their project needs. The architecture combined with

extensive low-power modes is optimized to achieve extended battery life in portable measurement applications.

MSPM0H321x 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™ kit available for

purchase and design files for a target-socket board. 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.
