MSP430FR59691IRGZT Technical Specifications

MSP430FR59691IRGZT Key Features

• FRAM nonvolatile memory with fast, byte?write capability benefits log and calibration storage with lower write latency than flash.
• 16?bit MSP430 core delivers efficient code density and deterministic interrupt response for real?time control tasks.
• Low operating voltage and ultralow standby modes reduce power draw, improving battery life in portable and remote systems.
• Integrated mixed?signal peripherals (12?bit ADC, timers, eUSCI) simplify system integration and reduce external component count.

Typical Applications

• Battery?powered sensor nodes requiring fast nonvolatile logging, long battery life, and low wake latency for short duty?cycle measurements.
• Industrial metering where accurate ADC conversion, nonvolatile calibration, and predictable interrupt timing improve measurement integrity and uptime.
• Human?machine interfaces and capacitive touch systems that need low power, integrated peripherals, and ample FRAM for configuration storage.
• Embedded controllers in portable medical devices where low quiescent current, safe nonvolatile state retention, and compact integration matter.

MSP430FR59691IRGZT Advantages vs Typical Alternatives

The device combines FRAM speed and endurance with a 16?bit MSP430 core to offer lower write latency and higher write endurance than typical flash?based microcontrollers. It runs at comparable clock speeds while drawing less power in standby. Integrated 12?bit ADC and multiple serial interfaces reduce the need for external components versus discrete solutions. These traits translate to faster nonvolatile updates, fewer system parts, and longer field life in battery?sensitive and metering applications.
