Overview

The MSP430F1491IPM is a 16-bit RISC-based microcontroller from Texas Instruments designed for ultra-low-power sensing and measurement applications. It features 60KB of Flash memory and 2KB of RAM, operating at speeds up to 8MHz while maintaining extremely low current consumption in multiple power-saving modes.

Why Choose This Part

This MCU offers a versatile 16-bit RISC architecture with five distinct power-saving modes, including a standby mode that consumes only 32uA. Its integrated peripherals, such as the 16-bit Timer_B with seven capture/compare registers, provide significant flexibility for complex timing and PWM requirements in a compact 64-LQFP package.

Applications

Battery-Powered Sensing
Ideal for remote sensors and handheld instruments due to its low standby current and fast 6 microsecond wakeup time.
Industrial Data Logging
Utilizes its 60KB Flash and serial interfaces to capture and store data from industrial analog-to-digital slope converters.
Utility Metering
Commonly used in flow and energy meters that require long-term operation on a single battery with minimal maintenance.
