The 8 KB of SRAM handles stack and scratchpad, while the 17-channel 12-bit ADC captures analog inputs without an external converter. ## Industrial temperature range and peripheral set The 54 I/O lines in a 64-LQFP package give plenty of headroom for a mixed-signal board with parallel buses or a keypad matrix. ## Active lifecycle and supply posture 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.","metaTitle":"TI MSP430FR5994IPMR 16-bit MCU, 16 MHz, 256 KB FRAM, 64-LQFP","metaDescription":"Texas Instruments MSP430FR5994IPMR 16-bit MCU with 16 MHz core, 256 KB FRAM, 8 KB RAM, 54 I/O, 17x12-bit ADC.

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."},{"question":"Is MSP430FR5994IPMR pin-compatible with other MSP430 LQFP-64 parts?","answer":"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."},{"question":"Does MSP430FR5994IPMR support JTAG or Spy-Bi-Wire programming?","answer":"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."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430FR5994IPMR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430FR5994IPMR when reusing this data.
