Overview

The MSP430G2231IPW14 is an ultra-low-power 16-bit RISC microcontroller from Texas Instruments' Value Line series, offering 2KB of Flash and 128 bytes of RAM. It is designed for battery-operated applications, featuring a fast wake-up time of less than 1 microsecond and multiple low-power modes to extend battery life. The integrated 10-bit ADC and serial communication capabilities make it suitable for simple sensor interfacing in compact designs.

Why Choose This Part

Choosing this part provides ultra-low power consumption with standby current as low as 0.5 uA and active mode current of 220 uA at 1 MHz. The 16-bit RISC architecture delivers 62.5-ns instruction cycle times, offering better performance-per-clock than 8-bit alternatives while maintaining a low cost for basic embedded tasks.

Applications

Battery-Powered Handheld Sensors
Utilizes the 0.5 uA standby current and 10-bit ADC to monitor environmental or physical sensors with minimal power draw.
Utility Metering Nodes
Acts as a low-cost, low-power interface for pulse counting or simple communication in smart metering applications.
Portable Consumer Electronics
Manages basic user interface tasks or system monitoring where small TSSOP-14 packaging and low cost are critical.
