Connectivity covers I²C, IrDA, LINbus, SPI, and UART/USART — enough to talk to an external radio, a shunt-based current sensor, or a host processor over a serial link. ## Supply range and 3.3 V compatibility Yes, it is fully compatible with 3.3 V logic — the Vcc/Vdd range covers it directly. The LCD driver can run off an internal charge pump, which simplifies the display bias supply for battery-powered handhelds or panel meters. ## Package and mounting Housed in a 128-LQFP (20x14 mm body), this is a surface-mount part intended for reflow assembly. The 0.4 mm pitch demands a controlled solder-paste stencil and a decent reflow profile — nothing exotic, but worth noting for a rework bench. MSL level is not listed in the record, but LQFP packages typically ship at MSL 3; treat the reel with standard moisture precautions if the seal is broken. ## Lifecycle and sourcing For dual-sourcing or a second-source gate, TI's MSP430F6xx family includes pin-compatible density variants — check the base product number MSP430F67491 for the exact Flash and RAM configuration you need.","metaTitle":"TI MSP430F67491AIPEUR 16-bit MCU, 25 MHz, 512KB Flash","metaDescription":"Texas Instruments MSP430F67491AIPEUR 16-bit MCU with 25 MHz CPU, 512KB Flash, 32K x 8 RAM, 4x24-bit sigma-delta ADC, 90 I/O, -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":"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":"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":"MSP430F67491","Program Memory Size":"512KB (512K 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":"$11.4927","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/94013ff2fb2ad301a731e282d067c425.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can MSP430F67491AIPEUR be used for battery-powered LCD applications?","answer":"Yes.
