This part carries an Obsolete lifecycle status. TI no longer manufactures the MSP430F67451IPZR in volume, and no official last-time-buy window is open. For production builds, you will need to source from independent distribution on a quoted-to-order basis. No direct successor order code is listed; the MSP430F6xx family includes pin-compatible density variants, but verifying exact peripheral compatibility against your firmware is essential before committing a board spin. ## Peripheral set — the sigma-delta ADC array is the differentiator The four 24-bit sigma-delta converters are the headline feature here. They are designed for direct connection to current and voltage sensors in polyphase energy meters, eliminating the need for external analog front-ends. The LCD driver supports segment displays common in utility meters and panel instruments. Brown-out detect and POR are integrated, so external reset supervision is optional in most designs.","metaTitle":"TI MSP430F67451IPZR 16-bit MCU, 25 MHz, 128 KB Flash","metaDescription":"Texas Instruments MSP430F67451IPZR 16-bit MCU with MSP430 CPUXV2 core at 25 MHz, 128 KB Flash, 16 KB RAM, 4x24-bit SD ADC, LCD driver. -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"25MHz","Series":"MSP430F6xx","Package":"Tape & Reel (TR)","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":"Obsolete","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/35ccd3fb89d5bb6f907ce9a244b44892.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430F67451IPZR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430F67451IPZR when reusing this data.
