Product details

64 KB FRAM — no erase cycles, no wear concern

Its 64 KB program memory uses FRAM — ferroelectric RAM — which combines non-volatile storage with fast write speeds and 10^15 write-cycle endurance, eliminating the erase-before-write penalty of Flash. This makes it a strong fit for data-logging, metering, and sensor nodes where the MCU writes to its own program space frequently or needs instant-on capability.

The 40 general-purpose I/O pins and integrated 12-bit ADC (16 channels) support typical sensor-interface and control tasks.

48-VQFN package and footprint

Housed in a 48-VFQFN Exposed Pad (7x7 mm body), the MSP430FR5869IRGZT requires a surface-mount reflow profile.

Connectivity and serial interfaces

An internal oscillator is available, reducing external component count for cost-sensitive boards.

Frequently asked questions

How much FRAM does MSP430FR5869IRGZT have?

64 KB of FRAM program memory, organized as 64K x 8 bits. FRAM is non-volatile with no erase-cycle overhead, unlike Flash.

What is the difference between MSP430FR5869IRGZT and MSP430FR5969?

Both are MSP430 FRAM MCUs in the same family. The MSP430FR5969 typically offers higher memory density and additional peripherals. For a pin-compatible alternative within the same package, verify the specific memory and peripheral requirements against the datasheet; the FR5869 is the 64 KB FRAM variant.
