Overview

The MSP430F5172IRSBT is a 16-bit ultra-low-power microcontroller from Texas Instruments based on the CPUXV2 architecture. Operating at up to 25MHz, it features 32KB of Flash and 2KB of RAM, optimized for battery-powered applications requiring precise analog sensing via its integrated 10-bit ADC.

Why Choose This Part

This MCU offers a highly efficient power management system with a programmable LDO and multiple low-power modes to extend battery life. The 25MHz performance in a compact 5x5mm WQFN package provides a strong balance of processing power and footprint for space-constrained designs.

Applications

Battery-Powered Sensing
Ideal for portable instruments that require long battery life, utilizing the 0.25uA shutdown current and 0.9uA sleep modes.
Industrial Sensors
Suitable for 4-20mA loop-powered sensors or wireless nodes using the integrated 11-channel 10-bit ADC and SPI/I2C interfaces.
Utility Metering
Used in flow or gas meters where the flexible clock system and brown-out reset ensure reliable long-term operation.
