Product details

MSP430FR2532IRGET — 16-bit FRAM MCU for low-power sensing and control

FRAM memory: no wear-leveling, no write-cycle worry

Unlike Flash-based MCUs, FRAM writes at full speed without erase cycles and tolerates orders of magnitude more write operations — effectively unlimited for most embedded applications. That means you can log data, update firmware over the air, or store calibration constants without managing wear-leveling in software. The 8.5 KB program space is tight for complex stacks but sufficient for a dedicated sensor hub or a simple control loop with a bootloader.

Package and footprint: 24-VQFN with exposed pad

The 15 I/O pins are enough for a handful of sensors, a small display, and a serial link, but not for a memory bus or parallel interface.

For dual-sourcing resilience, the MSP430 FRAM family includes pin-compatible density variants — verify the exact memory and peripheral set against your firmware image before substituting.

Frequently asked questions

What is the difference between MSP430FR2532IRGET and MSP430FR2433IRGET?

Both are 16-bit MSP430 FRAM MCUs in the same family. The FR2433 variant typically offers larger FRAM and SRAM capacities and additional peripherals. Check the respective datasheets for exact memory sizes and feature sets — the base product numbers differ, so verify pin compatibility for your PCB layout.

Does MSP430FR2532IRGET have a replacement or equivalent part?

The MSP430 FRAM family includes pin-compatible density upgrades within the same package — confirm memory and peripheral fit against your firmware before selecting an alternative.
