The four 24-bit sigma-delta converters are the part's defining feature. They allow simultaneous sampling of multiple analog channels — think three-phase power monitoring plus neutral current, or multi-axis load-cell readout — without an external multiplexer or separate ADC IC. The 24-bit resolution gives the dynamic range to resolve microvolt-level signals in the presence of a large DC offset, which is exactly what energy metering and precision weigh-scale applications need. For a BOM engineer, this means the MSP430F6745IPEU collapses what would be a multi-chip analog front-end into one MCU, saving board area and reducing the calibration burden across separate converter parts. ## Segment LCD driver and 90 I/O for system integration The on-chip LCD driver drives a segmented glass display directly — no external display controller or driver IC. Combined with 90 general-purpose I/O pins, this MCU can handle a local user interface (display plus pushbuttons or a small keypad) alongside the sensor interface and communication links. The I/O count is high for a 128-pin LQFP: 90 pins leaves headroom for parallel data buses, multiple chip selects, and discrete control signals without needing a port expander. The 128-LQFP package (20x14 mm body) is a standard footprint with broad second-source assembly support, so the supply chain is not locked to a single packaging house.","metaTitle":"MSP430F6745IPEU 16-bit MCU, 25 MHz, 128 KB Flash","metaDescription":"Texas Instruments MSP430F6745IPEU 16-bit MCU with MSP430 CPUXV2 core at 25 MHz. 128 KB Flash, 16 KB RAM, 4x24-bit sigma-delta ADC, LCD driver, 90 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":"Tray","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":"MSP430F6745","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":"$11.8129","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a22d777df21e2845026cc499330e309e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MSP430F6745IPEU support I²C and SPI?","answer":"Yes.
