Product details

128 KB FRAM — the main event

Its headline feature is 128 KB of FRAM program memory, which combines non-volatile storage with fast write endurance — you can treat it like EEPROM without worrying about wear-leveling, and it writes at near-SRAM speed. The 16 MHz clock is enough for sensor fusion loops, UART protocol handling, and real-time control tasks in industrial or battery-powered gear.

I/O and connectivity for a 100-pin part

With 83 general-purpose I/O lines in a 100-LQFP (14x14 mm) package, this MCU gives you plenty of headroom for parallel LCD interfaces, keypad matrices, or multiple sensor interrupts. The 16-channel, 12-bit ADC handles analog inputs from thermistors, potentiometers, or current shunts without an external converter.

Frequently asked questions

What are alternatives to MSP430FR68891IPZ?

Within the MSP430 FRAM family, pin-compatible alternatives with different memory densities exist, but the exact 128 KB FRAM + 100-LQFP combination is specific to this base product number. For a drop-in replacement, check the MSP430FR6889x series variants in the same 100-LQFP package.
