MSP430FR5994IRGZR 16-bit FRAM Microcontroller, IRGZR Package

MSP430FR5994IRGZR Overview

The MSP430FR5994IRGZR is an ultra?low?power, 16?bit microcontroller built around the MSP430? architecture with nonvolatile FRAM. It targets battery?sensitive and instrumentation designs that need faster wakeup, more write endurance, and lower active energy than many flash?based MCUs. The device balances low active current with rich peripherals for sensing, timing, and communication. For more purchasing and distribution details visit IC Manufacturer.

MSP430FR5994IRGZR Technical Specifications

MSP430FR5994IRGZR Key Features

• 16?bit RISC core with deterministic instruction timing for predictable real?time control and efficient code density.
• 256 KB FRAM delivers high write endurance and lower write energy, which matters for frequent logging and configuration updates.
• Ultra?low power modes reduce standby current to microamp levels so designs run longer on smaller batteries.
• Flexible peripherals including multiple timers, analog converters, and serial interfaces to simplify integration and reduce BOM count.

Typical Applications

• Battery?powered metering and data loggers that need frequent nonvolatile writes and long lifetime in fielded systems using FRAM for durable storage.
• Industrial sensing nodes that require fast wakeup, deterministic control, and robust analog front?end support for precision measurement and signal conditioning.
• Portable medical instruments that demand low active energy, reliable nonvolatile parameter storage, and multiple communication interfaces for data transfer.
• Consumer and handheld devices where lower write energy, rapid resume from low power, and a compact package reduce system cost and extend battery life.

MSP430FR5994IRGZR Advantages vs Typical Alternatives

The device offers higher write endurance and lower write energy versus flash?based microcontrollers because FRAM supports many more write cycles with less energy per write. It also provides faster wakeup from low?power states, which yields lower average power in burst?measurement and data?logging scenarios. The 16?bit MSP430 core gives smaller code size and deterministic timing compared to many 32?bit alternatives for control?centric tasks.

FAQ

What memory type is used?

The device uses FRAM for program and data storage. FRAM provides nonvolatile retention with much higher write endurance and lower write energy than typical flash memories, making it suitable for frequent writes.

What supply range does it support?

Supply voltage support spans typical embedded ranges from 1.8 V to 3.6 V. This allows compatibility with single?cell lithium and many regulated systems commonly used in portable and industrial designs.

Is it suitable for battery?powered designs?

Yes. The MCU has multiple ultra?low?power modes and fast wakeup. These features reduce average power in intermittent?sampling and event?driven systems, extending battery life over many alternatives.

Which package does it come in?

The IRGZR suffix denotes a 64?pin LQFP package type. This package provides a balance of I/O count and board?level routing ease for medium?complexity embedded systems.

What development support is available?

Typical support includes TI development tools, code examples, and evaluation modules for the MSP430 family. These resources accelerate prototyping, debugging, and integration into production designs.
