Texas Instruments MSPM0H321x/-Q1 Mixed-Signal Microcontrollers
Texas Instruments MSPM0H321x/-Q1 Mixed-Signal Microcontrollers (MCUs) are based on the enhanced Arm® Cortex®-M0+ core platform operating at a frequency of up to 32MHz. These cost-optimized modules operate with supply voltages from 4.5V, support an extended temperature range of -40°C to +125°C, and feature high-performance analog peripheral integration. The series provides up to 64KB embedded flash program memory with 8KB SRAM and includes a high-speed on-chip oscillator with up to ±1.2% accuracy, eliminating the need for an external crystal. The MCU's architecture and low-power modes are optimized to achieve extended battery life in portable measurement applications. Typical applications for TI MSPM0H321x/-Q1 MCUs include medical and healthcare, personal electronics, connected peripherals and printers, appliances, factory automation control, and lighting.
