The Flash is field-reprogrammable, so firmware updates over UART or SPI are feasible if the bootloader is planned for. The 32 KB RAM is shared between data and stack — for designs logging interval data or running multiple ADC channels, budget the heap carefully. ## The four 24-bit sigma-delta ADCs — where this part earns its keep The four 24-bit sigma-delta ADCs are designed for low-frequency, high-resolution measurement. ## Lifecycle and sourcing posture For BOM planning, this removes the last-time-buy risk that haunts older MSP430 derivatives.","metaTitle":"TI MSP430F67491AIPZ 16-bit MCU, 25 MHz, 512 KB Flash","metaDescription":"Texas Instruments MSP430F67491AIPZ 16-bit MCU with 25 MHz CPUXV2 core, 512 KB Flash, 32 KB RAM, four 24-bit sigma-delta ADCs, LCD driver, 100-LQFP.","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":"32K 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":"MSP430F67491","Program Memory Size":"512KB (512K 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":"$14.2240","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/94013ff2fb2ad301a731e282d067c425.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to MSP430F67491AIPZ in this component family?","answer":"Within the MSP430F6xx series, there are several density and peripheral variants sharing the 100-LQFP footprint. The base product number MSP430F67491 covers this exact Flash and RAM configuration. For a pin-compatible swap, look at other MSP430F67xx devices in the same 100-pin package — they share the same core and peripheral map but may differ in ADC channel count or LCD segment support. Confirm the specific peripheral requirements against the datasheet before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430F67491AIPZ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430F67491AIPZ when reusing this data.
