Product details

256 KB FRAM — what it changes for the design

What sets it apart from conventional Flash-based MCUs is the 256 KB FRAM program memory: FRAM writes at bus speed with no erase cycle, draws negligible write current, and is rated for 10^15 write cycles. The 8 KB of SRAM handles stack and scratchpad, while the 17-channel 12-bit ADC captures analog inputs without an external converter.

If you are dual-sourcing, the base product number MSP430FR5994 spans multiple package variants, so a pin-compatible LQFP-64 sibling (e.g., the MSP430FR5994IPM, which differs only in the reel/tube suffix) shares the same die and footprint.

Frequently asked questions

What is the difference between MSP430FR5994IPMR and MSP430FR5994IPM?

The two share the same die, package (64-LQFP), and electrical ratings. The suffix 'R' in MSP430FR5994IPMR indicates Tape & Reel packaging, while the MSP430FR5994IPM ships in tubes. Functionally they are identical — the choice is a logistics preference for your pick-and-place line.

Is MSP430FR5994IPMR pin-compatible with other MSP430 LQFP-64 parts?

Yes, the MSP430FR5994IPMR uses the standard 64-LQFP (10x10 mm) footprint that is common across many MSP430 FRAM and Flash MCUs in the same package. A board designed for the MSP430FR5994IPMR will typically accept a pin-compatible LQFP-64 sibling from the MSP430 family, provided the supply voltage and peripheral set match the application.

Does MSP430FR5994IPMR support JTAG or Spy-Bi-Wire programming?

The MSP430 FRAM family, including this part, supports both JTAG and Spy-Bi-Wire (SBW) debug/programming interfaces. SBW uses only two pins (SBWTDIO and SBWTCK) and is the standard connection for production programming and field updates.
