With 90 general-purpose I/O lines in a 128-LQFP package (20x14 mm body), this MCU can handle the parallel sensor inputs and display segments common in panel-mount instruments. ## Temperature range and supply The internal oscillator keeps BOM count low for applications that don't require an external crystal, though the clock tree supports external sources when tighter timing is needed. ## Lifecycle and sourcing Listed as Active by Texas Instruments — no end-of-life notification, no last-time-buy pressure.","metaTitle":"TI MSP430F67661AIPEU 16-bit MCU, 25MHz, 256KB Flash","metaDescription":"Texas Instruments MSP430F67661AIPEU 16-bit MCU with 25MHz CPUXV2 core, 256KB Flash, 16KB RAM, 6x24-bit sigma-delta ADC, 90 I/O, -40 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, 6x24b Sigma Delta Converter","Connectivity":"I²C, IrDA, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"90","Core Processor":"MSP430 CPUXV2","Package / Case":"128-LQFP","Product Status":"Active","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F67661","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"128-LQFP (20x14)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.9747","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/94013ff2fb2ad301a731e282d067c425.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is MSP430F67661AIPEU's listed speed?","answer":"The core runs at 25 MHz.

The MSP430F67661AIPEU sits at the high end with 256 KB Flash and six 24-bit sigma-delta converters. Lower-density siblings (e.g., 128 KB Flash, fewer ADC channels) share the same 128-LQFP footprint and peripheral set, making them drop-in options for cost-reduced BOMs when the full ADC count or memory isn't needed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430F67661AIPEU","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430F67661AIPEU when reusing this data.
