128 KB FRAM — no erase penalty, unified memory
The MSP430FR6889IPNR: Its 128 KB of FRAM program memory is the standout feature: FRAM combines the speed of SRAM with the non-volatility of Flash, but without the erase-before-write cycles. That means you can treat it as unified memory — code, data, and configuration all in one space — and write to it byte-by-byte at full bus speed. For a firmware-update scheme or a data-logging application that stores calibration constants, this eliminates the wear-leveling and sector-erase overhead you'd budget with a Flash part. The part carries 2K x 8 of RAM for stack and scratchpad, 63 general-purpose I/O lines, and an integrated 12-channel 12-bit ADC.
Texas Instruments lists the MSP430FR6889IPNR as Active.
