MSP430FR2476TRHAR 16-bit FRAM Microcontroller (TRHAR Package)

MSP430FR2476TRHAR Overview

IC Manufacturer The MSP430FR2476TRHAR is a low?power 16?bit microcontroller in the MSP430 FRAM family. It combines a compact 16?bit CPU with nonvolatile FRAM to deliver faster write cycles, higher endurance and lower active energy than typical flash?based alternatives. The device targets battery?sensitive and intermittent?power industrial designs that need up to double the write endurance and significantly lower write latency compared with mainstream flash MCUs.

MSP430FR2476TRHAR Technical Specifications

MSP430FR2476TRHAR Key Features

• 16?bit MSP430 core ?? delivers compact code and deterministic real?time performance for control tasks.
• FRAM nonvolatile memory ?? enables high write endurance and faster write cycles, which matters for frequent data logging or parameter storage.
• Wide supply range ?? 1.8?C3.6 V operation supports more battery chemistries and tolerant power rail designs compared with narrow?range MCUs.
• Multiple low?power modes ?? reduces standby and active energy for up to orders?of?magnitude longer battery life in typical sensor and portable systems.
• Compact integration ?? combined on?chip nonvolatile storage, RAM and peripherals reduce board area and component count relative to separate-memory solutions.

Typical Applications

• Battery?operated sensor nodes and wireless endpoints where FRAM endurance and fast writes support frequent local logging and in?field firmware updates without large power penalties.
• Smart metering endpoints that require reliable nonvolatile storage of counters and configuration with higher write endurance than flash for long service life.
• Industrial control modules that need deterministic 16?bit processing and low standby current to keep remote devices online for years on primary cells.
• Consumer and handheld devices where compact code size, quick nonvolatile data commits and wide supply compatibility reduce BOM cost and improve user experience.

MSP430FR2476TRHAR Advantages vs Typical Alternatives

The device uses FRAM, which provides faster write times, higher endurance, and lower energy per write compared with many flash?based MCUs. The 16?bit MSP430 core offers simple, deterministic operation and smaller code size vs many 32?bit alternatives for control?oriented tasks. Its 1.8?C3.6 V range and multiple low?power modes enable longer battery life and broader battery chemistry support than parts limited to a narrower voltage window.

FAQ

What CPU core does it use?

The device uses a 16?bit MSP430 RISC core designed for low power and deterministic interrupt handling. This core achieves compact code size and efficient real?time control for embedded tasks.

What is FRAM and why use it?

FRAM is a nonvolatile memory technology that offers faster writes, lower energy per write and far higher write endurance than typical flash, making it suited for frequent data logging and in?field parameter updates.

What supply voltage range is supported?

It supports a wide supply range of 1.8 V to 3.6 V, enabling compatibility with multiple battery types and tolerant operation in mixed?rail systems common to industrial and portable designs.

How does it save power in battery systems?

Multiple low?power modes let designers trade active functionality for minimal standby current. Combined with FRAM??s low write energy, this reduces overall energy consumption compared with flash?based alternatives.

How is the part supplied for manufacturing?

The suffix indicates tape?and?reel shipping (TR). The package code in the ordering part denotes the specific physical package, which supports automated pick?and?place and high?volume assembly workflows.
