The 128-LQFP package (20x14 mm body) is a common footprint for mid-density I/O designs; the 0.4 mm pitch demands careful PCB routing but is well within standard assembly capability. ## Peripheral set for metering and control Beyond the six sigma-delta ADCs, the device integrates a brown-out detect/reset, DMA controller, PWM timer, watchdog timer, and an internal oscillator — reducing external BOM count. The 8x10-bit auxiliary ADC handles auxiliary measurements (temperature, voltage reference monitoring) without loading the sigma-delta channels. The LCD driver supports segment displays common in utility meters and industrial panels.","metaTitle":"TI MSP430F67691AIPEUR 16-bit MCU, 25MHz, 512KB Flash","metaDescription":"Texas Instruments MSP430F67691AIPEUR 16-bit MCU with 25MHz CPUXV2 core, 512KB Flash, 32KB RAM, six 24-bit sigma-delta ADCs, LCD driver, -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, 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":"MSP430F67691","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":"Is MSP430F67691AIPEUR a direct replacement for MSP430F67691AIPN?","answer":"The base product number MSP430F67691 is identical; the suffix difference is packaging only. The AIPEUR variant ships in tape and reel (TR), while the AIPN variant ships in a tray (PN). Electrically and functionally they are the same die and firmware-compatible. Verify your assembly line's preferred media format before substituting."},{"question":"Does MSP430F67691AIPEUR come in tube packaging?","answer":"No — the AIPEUR suffix designates tape and reel (TR) packaging. The tray-pack variant is MSP430F67691AIPN.
