Product details

128 KB FRAM — the zero-wear memory that changes the firmware-update calculus

The 2 KB SRAM complements it for stack and scratchpad, and the 48 GPIOs with a 12-bit, 12-channel ADC give it enough I/O for sensor-heavy control boards.

If you are designing a new board, do not spec this code; look for a current MSP430FRxx variant with equivalent FRAM density and peripheral set.

Peripheral set and connectivity for a mixed-signal control node

The MSP430FR58891IRGCR integrates a brown-out detect and reset, POR, DMA controller, PWM timers, and a watchdog timer — the usual set for an autonomous sensor or actuator controller.

64-VFQFN — footprint and thermal reality

The package is a 64-lead VFQFN with an exposed pad, 9x9 mm body (64-VQFN per the supplier device code).

Frequently asked questions

What is the replacement for MSP430FR58891IRGCR?

Texas Instruments has not published a direct pin-compatible successor for the MSP430FR58891IRGCR. For a new design, look at current MSP430FRxx family members with similar FRAM density (128 KB) and peripheral set — the MSP430FR599x or MSP430FR604x series, for example, offer comparable or expanded capability in the same 64-QFN footprint. Confirm pin compatibility against the target package variant before committing the layout.

How much FRAM and RAM does MSP430FR58891IRGCR have?

The MSP430FR58891IRGCR has 128 KB of FRAM program memory (organized as 128K x 8 bits) and 2 KB of SRAM (2K x 8 bits). The FRAM is byte-addressable, fast-write, and non-volatile with endurance far exceeding Flash — suitable for data logging and frequent firmware updates without wear-leveling.

What package is MSP430FR58891IRGCR?

The exposed pad requires a thermal land with via stitching for adequate heat dissipation.
