The part integrates a 4-channel 24-bit sigma-delta ADC for high-resolution sensor inputs, an LCD driver for driving the display without external chips, and 90 general-purpose I/O lines for control and communication. ## Built-in LCD driver saves board space and BOM cost One of the standout features on this die is the integrated LCD controller — it can drive a segment LCD panel directly, eliminating the need for a separate display driver IC. For a panel retrofit or a new meter design, that means one fewer component to source, one fewer footprint on the board, and a simpler firmware path. The peripheral set also includes a brown-out detect, POR, PWM timer, and watchdog timer, so the MCU can run a self-contained system with minimal external supervision. The temperature grade is industrial: -40°C to 85°C, rated for outdoor enclosures, engine-bay-adjacent cabinets, or unheated utility rooms. If you are repairing a meter in the field, this part will handle the thermal swing without a hiccup. For a storeroom keeper planning a five-year spares strategy, this part is still a safe line item — no need to squirrel away a lifetime buy today. That said, the 128-LQFP package (20x14 mm body) is a standard footprint, and the part ships in tubes, so storing a few reels dry for long-term backup is straightforward.","metaTitle":"MSP430F6746AIPEU 16-bit MCU, 25 MHz, 256 KB Flash","metaDescription":"Texas Instruments MSP430F6746AIPEU 16-bit MCU, 25 MHz, 256 KB Flash, 16 KB RAM, LCD driver, 4x24b 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":"Tube","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":"MSP430F6746","Program Memory Size":"256KB (256K 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":"$11.9747","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/87bbda703b256feee860450caa184c15.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MSP430F6746AIPEU obsolete or active?","answer":"No discontinuation or last-time-buy has been announced."},{"question":"Does MSP430F6746AIPEU have a built-in LCD driver?","answer":"Yes, the peripheral set includes an LCD driver, so it can drive a segment LCD panel directly without an external display controller."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430F6746AIPEU","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430F6746AIPEU when reusing this data.
