Overview

The MSP430F449IPZ is a 16-bit RISC microcontroller from Texas Instruments designed for ultra-low power consumption in battery-powered applications. It features 60KB of Flash memory, an integrated LCD controller, and a high-precision 12-bit A/D converter, making it ideal for portable instruments and sensor nodes. The device is optimized for fast wake-up times from standby mode in less than 6 microseconds.

Why Choose This Part

This MCU offers exceptional power efficiency with a shutdown current of only 0.1 uA and multiple low-power modes for fine-tuned energy management. The inclusion of an integrated LCD driver reduces system BOM cost and PCB complexity for display-centric products. Its 12-bit ADC with internal reference and autoscan allows for sophisticated signal processing without constant CPU intervention.

Applications

Handheld Metering
Utilizes the integrated LCD driver and 12-bit ADC for digital multimeters or environmental monitoring tools.
Industrial Sensor Nodes
Ideal for remote sensors requiring long battery life and periodic data logging with low-power standby modes.
Medical Monitoring
Suitable for portable health devices like glucose meters that require precise analog measurement and low active current.
Smart Utility Meters
Manages flow measurement and display functions in water or gas meters with minimal energy footprint.
