Active production, FRAM-based 16-bit MCU for industrial sensing
It combines 128 KB of FRAM program memory with 8 KB of SRAM, giving you unified non-volatile storage that writes at bus speed and draws negligible current in standby — a practical advantage over Flash for data-logging and over-the-air update buffers where every microamp counts. The built-in brown-out reset, POR, DMA, PWM timer, and watchdog timer cover the usual housekeeping blocks without external glue logic.
128 KB FRAM — what it changes for firmware and data storage
FRAM (ferroelectric RAM) is the headline feature here. Unlike Flash, FRAM writes at full bus speed with no erase-before-write cycle, so you can treat it as a unified memory for both code and data without wear-leveling. Endurance is effectively unlimited for normal product lifetimes — the datasheet typically quotes 10¹⁵ write cycles, which removes the sector-management overhead you would need on a Flash part. For a design that logs sensor data or stores calibration parameters frequently, this simplifies the firmware architecture and reduces the risk of write-disturb corruption.
64-pin LQFP — hand-solderable and rework-friendly
The MSP430FR5992IPMR comes in a 64-lead LQFP with a 10x10 mm body and 0.5 mm pitch. That is a standard footprint that reflows cleanly with a hot-air station or a reflow oven, and the leads are visible for inspection and touch-up. If you are prototyping or doing a low-volume build, this package is straightforward to hand-solder with a fine-tip iron and some flux.
The base product number MSP430FR5992 covers a range of package and temperature variants, so if you later need a different package or a wider temperature grade, the family has options without a core architecture change.
