MSP430FR2675TRHAR FRAM Microcontroller (TRHAR package)

MSP430FR2675TRHAR Overview

The MSP430FR2675TRHAR is an ultra-low-power 16-bit microcontroller built for battery-powered and industrial control nodes that need nonvolatile, fast write memory and compact peripheral integration. It combines a low-energy MSP430 core with FRAM for high write endurance and fast in-system updates, offering lower active and standby currents compared with typical flash-based MCUs. This device targets metering, sensor interfaces, and portable instrumentation where reliable nonvolatile storage, deterministic wake-up, and integrated analog and serial peripherals reduce system cost and complexity. See IC Manufacturer for ordering and packaging details.

MSP430FR2675TRHAR Technical Specifications

MSP430FR2675TRHAR Key Features

• FRAM nonvolatile memory that supports frequent writes with lower energy per write, enabling more in-field logging and calibration than flash.
• 16?bit MSP430 core that delivers efficient code density and reduced instruction cycles versus many 8?bit controllers.
• Ultra?low power modes for extended battery life, reducing standby consumption compared with comparable flash?based MCUs.
• Integrated 12?bit ADC and multiple timers to simplify sensor measurement, reduce external components, and shorten design cycles.
• Multiple serial interfaces (UART/SPI/I2C) for flexible connectivity to sensors, radios, and power-management ICs in many system topologies.

Typical Applications

• Battery-powered sensor nodes requiring frequent configuration or data-logging updates, where FRAM enables more write cycles and lower write energy than flash.
• Utility metering and energy monitoring designs that need deterministic nonvolatile storage for tariff tables, counters, and calibration parameters.
• Portable medical and instrumentation equipment that benefit from low active and sleep currents and accurate 12?bit analog acquisition for sensor front-ends.
• Industrial control and human?machine interfaces that require multiple serial buses, real-time timers, and robust nonvolatile memory for firmware and state retention.

MSP430FR2675TRHAR Advantages vs Typical Alternatives

The device uses FRAM instead of flash, offering far more write cycles and faster in-system updates, which means fewer external components and fewer design trade-offs. At a typical maximum clock of 16 MHz and sub?microsecond wake times, it provides more deterministic response than many lower?power 8?bit parts while consuming less energy in standby than many mainstream 32?bit MCUs. Its integrated 12?bit ADC, multiple timers, and serial interfaces reduce BOM count and save PCB area compared with discrete solutions.
