An internal oscillator keeps the BOM lean for cost-sensitive meter designs. The 80-LQFP package (12x12 mm body) with 52 available I/O provides enough signal routing for multiple sensor inputs, display segments, and communication lines without requiring a dense BGA footprint. Surface-mount assembly keeps production costs predictable. ## Active lifecycle — no near-term redesign pressure This supports both new design-ins and ongoing production replenishment without forcing a last-time-buy decision.","metaTitle":"TI MSP430F67641AIPNR 16-bit MCU, 25 MHz, 128 KB Flash","metaDescription":"Texas Instruments MSP430F67641AIPNR 16-bit MCU with 25 MHz CPUXV2 core, 128 KB Flash, 8 KB RAM, three 24-bit sigma-delta ADCs, LCD driver, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"25MHz","Series":"MSP430F6xx","Package":"Tape & Reel (TR)","RAM Size":"8K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, LCD, POR, PWM, WDT, 3x24b Sigma Delta Converter","Connectivity":"I²C, IrDA, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"52","Core Processor":"MSP430 CPUXV2","Package / Case":"80-LQFP","Product Status":"Active","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F67641","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"80-LQFP (12x12)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.8406","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/639692088022cfa279f1eeedee1644b3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between MSP430F67641AIPNR and other MSP430 parts?","answer":"The key differentiator is the three integrated 24-bit sigma-delta ADCs, which target polyphase energy metering and precision measurement. Many MSP430 variants lack these high-resolution converters or include only one. The 128 KB Flash and 8K x 8 RAM are also sized for metrology firmware and calibration tables, not general-purpose control."},{"question":"Does MSP430F67641AIPNR have a built-in LCD controller?","answer":"Yes, the peripheral set includes an LCD driver, along with brown-out detect/reset, DMA, POR, PWM, and watchdog timer."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430F67641AIPNR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430F67641AIPNR when reusing this data.
