An integrated LCD driver lets the chip drive a segment display directly, cutting the component count on a meter or panel controller. ## Peripheral set for metering and industrial control Connectivity covers I²C, IrDA, LINbus, SPI, and UART/USART — enough to talk to external sensors, displays, and a host controller. With 62 I/O lines in a 100-pin LQFP (14x14 mm body), there is room for parallel interfaces and control signals without multiplexing.","metaTitle":"TI MSP430F67681IPZ 16-bit MCU, 25 MHz, 512 KB Flash","metaDescription":"Texas Instruments MSP430F67681IPZ 16-bit MCU with 25 MHz core, 512 KB Flash, 16 KB RAM, six 24-bit sigma-delta ADCs, LCD driver, I²C/SPI/UART.","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":"Tray","RAM Size":"16K 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":"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":"MSP430F67681","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/d25833ae3f3e8231a64b1693e0a84f1a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MSP430F67681IPZ have a built-in LCD driver?","answer":"Yes, the LCD peripheral is integrated on-chip, allowing direct drive of a segment LCD without an external display controller."},{"question":"What is the maximum operating frequency of MSP430F67681IPZ?","answer":"The core runs at 25 MHz, which is the maximum clock speed for this device."},{"question":"What are the direct alternatives to MSP430F67681IPZ?","answer":"Within the MSP430F6xx series, pin-compatible siblings vary by Flash density (e.g., 256 KB vs 512 KB) and ADC channel count.
