The 24-bit resolution gives the dynamic range to resolve small signals in the presence of large DC offsets — think current transformers on a power line or bridge-type pressure sensors. You still get the 8-channel 10-bit SAR ADC for faster auxiliary measurements like temperature or supply monitoring. ## LCD driver saves a display controller and board space The integrated LCD driver can directly drive a segmented glass LCD — common in utility meters, thermostats, and panel instruments — without a separate display controller chip. That means one fewer IC to source, one fewer serial bus to route, and a simpler BOM for cost-sensitive metering designs. ## 128-LQFP package and industrial temperature range Housed in a 128-LQFP with a 20x14 mm body, this part brings out 90 I/O pins — enough for a parallel LCD bus, multiple serial ports, and sensor interface lines. Supply voltage spans 1.8V to 3.6V, so it can run from a single lithium cell or a 3.3V regulated rail.","metaTitle":"TI MSP430F67451AIPEUR 16-bit MCU, 25MHz, 128KB Flash, LCD","metaDescription":"Texas Instruments MSP430F67451AIPEUR 16-bit MCU with 25MHz CPUXV2 core, 128KB Flash, 16KB RAM, integrated LCD driver and 4x24-bit sigma-delta ADC.","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":"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":"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":"MSP430F67451","Program Memory Size":"128KB (128K 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":"$7.4437","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/94013ff2fb2ad301a731e282d067c425.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MSP430F67451AIPEUR have an LCD driver?","answer":"Yes, it integrates an LCD controller capable of driving a segmented glass display directly, eliminating the need for a separate display driver chip."},{"question":"What is the closest pin-compatible alternative to MSP430F67451AIPEUR?","answer":"Within the MSP430F6xx series, there are density and peripheral variants that share the same 128-LQFP footprint.
