Overview

The MSP430FR5994IPNR is a 16-bit MSP430 microcontroller from Texas Instruments that uses FRAM for nonvolatile program and data storage (256 KB FRAM, 8 KB RAM). It runs up to 16 MHz, supports a wide 1.8 V to 3.6 V supply range, and exposes up to 68 I/O pins. The device targets ultra-low-power, battery-powered and energy-harvesting applications with integrated peripherals like DMA, timers/PWM, multiple serial interfaces (I2C, SPI, UART), and brown-out/POR reset features.

Why Choose This Part

FRAM provides fast, byte-writeable nonvolatile storage with very high endurance, eliminating typical flash write/erase cycles and allowing frequent in-field data logging and configuration changes. The MSP430 family is optimized for ultra-low power operation with multiple low-power modes and a wide supply range, making it practical for long-life battery or energy-harvesting designs. Integrated DMA and a rich set of serial peripherals simplify low-overhead data movement and communication.

Applications

Battery-powered sensing and data logging
Low active and standby currents plus high-endurance FRAM make it ideal for frequent sensor sampling and local nonvolatile data storage.
Smart metering and utility devices
Nonvolatile FRAM supports frequent configuration and ledger writes without wear, useful for tamper logs, counters, and calibration data.
Energy-harvesting sensor nodes
Wide supply range and ultra-low-power modes suit designs that run from solar, thermoelectric, or other energy-harvesting sources.
Industrial sensor interfaces and control
Multiple serial interfaces, DMA and many GPIOs enable protocol conversion, local I/O aggregation, and PWM-driven actuators.

Getting Started

Use the MSP-EXP430FR5994 LaunchPad development kit for a plug-and-play board with on-board debugger and breakout of the MCU pins. TI Code Composer Studio (CCS) and IAR Embedded Workbench both support building and debugging for this device; TI also provides MSP430Ware, DriverLib examples, and the Resource Explorer with peripheral examples. For simple sketches Energia can be used, and the device can be programmed/flashed with an MSP-FET or the LaunchPad on-board debugger.
