No official successor order code appears in the available ledger; procurement should calculate a lifetime-buy quantity against the installed base on the MRO contract rather than relying on ongoing channel availability. Authenticity screening is recommended given elevated counterfeit risk on EOL mixed-signal MCUs in broker channels."},{"question":"Is the MSP430F67641AIPN pin-compatible with the MSP430F67641AE or the MSP430F67741AE in 80-LQFP?","answer":"Both the MSP430F67641AE and MSP430F67741AE share the same 80-LQFP pinout footprint, but function differences exist in the Port 4 and Port 5 LCD segment driver multiplexing — the part variant letter suffix indicates the specific LCD segment count and port mapping configuration. Layout changes may be required for sigma-delta ADC reference routing on rev-C silicon; TI's errata sheet for the F67641 silicon revision is the authoritative reference, not the distributor record."},{"question":"Will the 3×24b sigma-delta ADC meet IEC 62056-21 Class B metering accuracy without external op-amp scaling?","answer":"The three 24-bit sigma-delta converters provide the resolution and simultaneous-sampling architecture needed for Class B accuracy, but meeting the full IEC 62056-21 Class B error budget depends on the shunt characterisation and calibration routine, not the ADC resolution alone. Full-flash erase cycles during firmware reflash will erase calibration constants stored in flash information memory unless protected — re-characterisation of the current shunt is required after a full erase-cycle reflash if the calibration data is not in protected flash segments."},{"question":"What is the realistic lead time and minimum order quantity for 25 pieces of MSP430F67641AIPN in tube?","answer":"EOL/hot lifecycle stage means lead times on 25-piece quantities can be allocation-constrained or subject to last-time-buy window closures with no firm distributor availability commitment. An RFQ should specify the target quantity and delivery timeline; the tube package is the standard pack format for this variant and is not a special-config option."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430F67641AIPN","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430F67641AIPN when reusing this data.
