Product details

FRAM MCU for low-power industrial sensing and logging

Its headline feature is 128 KB of FRAM program memory — non-volatile storage that writes at near-SRAM speed with essentially unlimited endurance, unlike Flash.

Brown-out detect and POR are integrated, so the reset supervisor is off the BOM.

Connectivity and peripheral set for interface-heavy designs

DMA offloads the CPUXV2 during peripheral transfers, which matters at 16 MHz when you are servicing a sensor burst without waking the core.

Package and PCB layout: 64-VQFN with exposed pad

The supplier device package is 64-VQFN (9x9), surface-mount only. MSL is not listed in the spec record, but QFN packages typically ship at MSL 3 — bake before reflow if the moisture-barrier bag has been open beyond the floor-life window. The 48 I/O count includes the ADC inputs and serial pins, so check the pin-multiplexing table in the datasheet before committing the layout.

Frequently asked questions

Is MSP430FR5989IRGCR RoHS compliant?

RoHS compliance is not explicitly stated in the spec record, but the lead-free finish (e4 / NiPdAu) on TI's QFN packages is standard for RoHS-compliant assemblies. Verify the specific date-code batch against the manufacturer's RoHS certificate if your compliance audit requires a paper trail.

Can MSP430FR5989IRGCR be programmed with the MSP-FET?

Yes, the MSP430FR5989IRGCR uses the standard Spy-Bi-Wire (SBW) 2-wire JTAG interface, which the MSP-FET programmer/debugger supports. The CPUXV2 core is fully compatible with TI's Code Composer Studio and IAR Embedded Workbench toolchains.

What is the difference between MSP430FR5989IRGCR and MSP430FR5994IRGCR?

Both are 16-bit MSP430 CPUXV2 FRAM MCUs in the same 64-VQFN package. The MSP430FR5994IRGCR offers a larger FRAM memory (256 KB vs 128 KB) and additional peripherals such as a hardware multiplier (MPY32) and a real-time clock (RTC) module. The MSP430FR5989IRGCR is the lower-cost, lower-density option for designs that do not need the extra memory or the RTC.
