The LCD driver supports up to 320 segments (4-mux), enough for a multi-line character display plus backlight control, eliminating a separate display controller IC. Connectivity options cover I²C, IrDA, LINbus, SPI, and UART/USART, giving flexibility for sensor buses and host communication in a mixed-signal control board. ## 62 I/O in a 100-pin LQFP — footprint and routing The 100-LQFP (14x14 mm) package provides 62 general-purpose I/O lines, sufficient for driving a segment LCD, reading a keypad matrix, and interfacing to multiple serial peripherals without port expansion. The 0.5 mm pitch is standard for hand-assembly and rework, though the fine pitch demands careful solder-paste stencil design for volume production.","metaTitle":"TI MSP430F67451AIPZR 16-bit MCU, 25 MHz, 128 KB Flash, LCD","metaDescription":"Texas Instruments MSP430F67451AIPZR 16-bit MCU with 25 MHz CPUXV2 core, 128 KB Flash, 16 KB RAM, 4x24b sigma-delta ADC, LCD driver, 62 I/O.","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":"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":"MSP430F67451","Program Memory Size":"128KB (128K 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":"$5.6376","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/94013ff2fb2ad301a731e282d067c425.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MSP430F67451AIPZR have an LCD controller?","answer":"Yes, the MSP430F67451AIPZR includes an integrated LCD driver peripheral, capable of driving up to 320 segments in 4-mux mode."},{"question":"What is MSP430F67451AIPZR's listed speed?","answer":"The MSP430F67451AIPZR is rated for a 25 MHz core clock speed with the MSP430 CPUXV2 processor."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430F67451AIPZR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430F67451AIPZR when reusing this data.
