MSP430FR5043IPMR

MSP430FR5043IPMR is TI’s ultra-low-power 16-bit microcontroller in the MSP430 FRAM family. It uses ferroelectric RAM (FRAM) for nonvolatile program and data storage, enabling fast writes, high endurance, and no need for external flash. The device combines a 16-bit MSP430 CPU with a rich set of peripherals, including ADC, analog comparator, timers, and the USCI module for UART/SPI/I2C, plus an RTC and GPIO. It supports multiple low-power modes with rapid wake-up, making it well suited for battery-powered sensing, metering, wearables, and portable devices. The IPMR suffix identifies a specific packaging/temperature option in TI’s catalog; check the TI product page for exact package (pin count) and electrical specs. Development is via Code Composer Studio with MSP430Ware.
