Product details

128 KB FRAM — no erase cycles, no wear limits

The MSP430FR69891IPZR: FRAM writes at bus speed and retains data without a battery. For a design that logs sensor data or updates firmware over the air, this eliminates the erase-page latency and endurance ceiling of Flash. The 2K x 8 RAM handles stack and scratchpad; the FRAM holds both code and non-volatile data in a single unified memory map.

Peripherals and I/O count

83 general-purpose I/O lines give room for a parallel LCD, keypad matrix, and multiple sensor interrupts. The internal oscillator frees a crystal for the main clock — one less BOM line.

Frequently asked questions

What is the supply voltage range of MSP430FR69891IPZR?

The supply range is 1.8 V to 3.6 V, covering 3.3 V regulated rails and single-cell Li-ion.

What is the difference between MSP430FR69891IPZR and MSP430FR69891IPZ?

The 'R' suffix indicates Tape & Reel packaging; the non-'R' variant ships in a different reel option. The silicon and pinout are identical.

What is the closest pin-compatible alternative to MSP430FR69891IPZR?

The MSP430FR6989IPZ (active, same 128 KB FRAM, same 100-LQFP) is a pin-compatible drop-in for production BOMs that need factory supply.
