The 100-LQFP package provides 62 I/O lines, and the supply range spans 1.8V to 3.6V. ## Sigma-delta ADC — the reason you pick this part over a general-purpose MCU The four 24-bit sigma-delta converters are the headline feature. They allow simultaneous sampling of multiple voltage and current channels in a polyphase energy meter, eliminating the need for an external ADC IC. The 24-bit resolution provides the dynamic range for class 0.2 metering accuracy without a separate analog front-end. The 8-channel 10-bit auxiliary ADC handles secondary measurements like temperature or tamper detection. ## Industrial temperature range and connectivity The integrated LCD driver (up to 4x multiplexed) offloads segment-display refresh from the core. ## Lifecycle status — no LTB concern for new designs Texas Instruments lists the MSP430F67451AIPZ as Active. The base product number MSP430F67451 covers the full family, so a pin-compatible Flash-memory or RAM variant can be selected without a PCB change.","metaTitle":"TI MSP430F67451AIPZ 16-bit MCU, 25MHz, 128KB Flash","metaDescription":"Texas Instruments MSP430F67451AIPZ 16-bit MCU in 100-LQFP. 25MHz MSP430 CPUXV2 core, 128KB Flash, 16K x 8 RAM, industrial temp -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":"Tube","RAM Size":"16K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, LCD, POR, PWM, WDT, 4x24b Sigma Delta Converter","Connectivity":"I²C, IrDA, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"62","Core Processor":"MSP430 CPUXV2","Package / Case":"100-LQFP","Product Status":"Active","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F67451","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.9199","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/94013ff2fb2ad301a731e282d067c425.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MSP430F67451AIPZ obsolete?","answer":"No. Texas Instruments lists the product status as Active."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430F67451AIPZ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430F67451AIPZ when reusing this data.
