Overview

The MSP430G2452IN20 is an ultra-low-power 16-bit RISC microcontroller featuring 8KB of Flash and 256 bytes of RAM in a hobbyist-friendly 20-pin PDIP package. It is designed for battery-operated sensing and control applications, capable of operating at up to 16MHz with a sub-microamp standby current.

Why Choose This Part

This MCU stands out for its extremely low power consumption across five different saving modes and its 16-bit RISC architecture which provides better performance-per-clock than standard 8-bit alternatives. The 20-PDIP package is a significant advantage for rapid prototyping and maintenance in industrial environments where through-hole components are preferred.

Applications

Battery-Powered Remote Sensors
Utilizes 0.5uA standby current and fast wake-up times (under 1us) to maximize battery life in periodic measurement systems.
Handheld Portable Instruments
The integrated 10-bit ADC with 8 channels allows for direct interfacing with analog sensors in compact, mobile devices.
Educational and Prototyping Projects
The through-hole PDIP package allows for easy use on breadboards and sockets without requiring surface-mount soldering.
Simple Low-Power Timing and Logic
Replaces discrete logic or power-hungry 8-bit MCUs in tasks requiring PWM, watchdog timers, or basic I2C/SPI communication.
