The official replacement is the MSP430F67641IRGE, which is pin-compatible and shares the same core, memory, and peripheral set. Stock of the IPN variant remains available through independent distribution — quoted to order."},{"question":"What is the replacement for MSP430F67641IPN?","answer":"The MSP430F67641IRGE is the recommended replacement. It uses the same 80-pin QFN footprint, CPUXV2 core at 25 MHz, 128 KB Flash, 8 KB RAM, and the three-channel 24-bit sigma-delta ADC. No PCB redesign is required."},{"question":"How much flash memory does MSP430F67641IPN have?","answer":"128 KB (128K x 8) of Flash program memory, paired with 8 KB (8K x 8) of RAM. This is sufficient for a metrology firmware stack plus moderate data logging."},{"question":"What is the pinout and footprint of MSP430F67641IPN?","answer":"The device is in an 80-LQFP package measuring 12x12 mm with 0.5 mm pitch. The pinout is identical to the MSP430F67641IRGE (80-pin QFN variant) — the datasheet landing page for the base product number MSP430F67641 provides the full pin assignment table."},{"question":"How does MSP430F67641IPN compare to MSP430F67641IRGE?","answer":"The IRGE variant is the direct pin-compatible replacement in an 80-pin QFN package (smaller footprint, same 12x12 mm body). The IPN ships in an 80-LQFP with exposed leads. Both share the same core, memory, ADC array, and peripherals. For new designs, the IRGE is the active TI recommendation; the IPN is end-of-life."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430F67641IPN","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430F67641IPN when reusing this data.
