MSP430FR5729IRHAT Technical Specifications

MSP430FR5729IRHAT Key Features

• FRAM nonvolatile memory delivers high write endurance and near-zero write latency, which reduces code and data update time compared with flash.
• 16-bit MSP430 core provides deterministic, low-overhead control code for time-critical tasks and lower code size than many 32-bit alternatives.
• Low-voltage operation from 1.8 V to 3.6 V enables battery-powered and energy-harvesting designs to operate over wider supply ranges than many competitors.
• Integrated 12-bit ADC and timers allow mixed-signal sensing and control without external converters, improving BOM cost and board area compared with discrete solutions.
• Multiple serial interfaces (UART/SPI/I2C) support flexible system integration and peripheral expansion with fewer external components.
• 8-channel DMA reduces CPU load and power by moving data autonomously between peripherals and memory during bursts of activity.

Typical Applications

• Battery-powered sensing nodes requiring frequent nonvolatile logging and fast wake-up for extended field life in remote industrial telemetry deployments.
• Portable medical instruments that need deterministic control, reliable nonvolatile parameter storage, and low active current for longer battery runtime.
• Smart sensors and actuators in building automation where mixed-signal inputs, accurate ADC conversions, and simple serial connectivity reduce system complexity.
• Industrial monitoring and control modules that benefit from FRAM endurance for frequent calibration updates and from robust low-voltage operation across systems.

MSP430FR5729IRHAT Advantages vs Typical Alternatives

The device combines FRAM and a 16-bit MSP430 core to offer faster nonvolatile writes and far higher write endurance than flash-based rivals. It runs at up to 16 MHz while supporting lower supply voltages, which yields better battery efficiency than many 32-bit parts at similar clock rates. Integrated ADC, timers, DMA, and multiple serial interfaces reduce the need for external components and lower total system cost.
