An integrated LCD driver supports segment displays directly, cutting the external display controller. The 128-pin LQFP package (20×14 mm body) gives access to 90 general-purpose I/O lines. ## What the six 24-bit sigma-delta converters mean for the BOM The 6x24b sigma-delta ADC block is the reason you pick this part over a general-purpose MSP430. Each converter runs simultaneously, so a three-phase-plus-neutral meter reads all voltage and current channels without multiplexing delay. The 24-bit resolution gives the dynamic range to measure shunt-resistor drops at light load and still resolve fault currents—no external PGA needed. The LCD driver saves a segment-driver IC and the associated board space. If your application does not need polyphase metering or a display, a smaller MSP430F6xx variant with fewer ADC channels and a smaller package (e.g., 100-pin LQFP) will cost less and simplify layout. ## Package and footprint notes The 128-LQFP package (20×14 mm body, 0.5 mm pitch) is a common footprint shared across the MSP430F6xx family. The exposed thermal pad on the underside requires a via-stitched ground plane for adequate heat dissipation—without it, the junction temperature rises quickly above 400 mA continuous I/O load.","metaTitle":"MSP430F67691IPEU 16-bit MCU, 512KB Flash, 25MHz, 128-LQFP","metaDescription":"Texas Instruments MSP430F67691IPEU 16-bit MCU with 512KB Flash, 32KB RAM, 25MHz, 6x24b sigma-delta ADC, LCD controller, 128-LQFP, -40 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":"Tray","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":"$16.1439","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d25833ae3f3e8231a64b1693e0a84f1a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MSP430F67691IPEU have an integrated LCD controller?","answer":"Yes, the MSP430F67691IPEU includes an integrated LCD driver as part of its peripheral set, capable of driving segment displays directly without an external controller."},{"question":"What is the difference between MSP430F67691IPEU and MSP430F67691?","answer":"The MSP430F67691IPEU is the specific orderable variant of the base MSP430F67691 device.
