They are not general-purpose SAR ADCs bolted on as an afterthought — they are the primary measurement path, clocked from the internal oscillator and designed for continuous conversion in a metrology loop. Each converter can be synchronized to the same sampling window, so a three-phase-plus-neutral power calculation gets phase-aligned voltage and current readings. The 90 I/Os and the LCD controller let the chip drive a local display and handle the communication stack (I²C, SPI, UART, IrDA, LINbus) without a second MCU. For a new design that needs a metrology-class MCU with an LCD driver, this part does not carry the supply risk of a phase-out part. ## Package and supply — what the layout needs The 128-LQFP (20x14 mm) is a surface-mount package. The internal oscillator can be used for the core clock.","metaTitle":"TI MSP430F6745AIPEU 16-bit MCU, 25 MHz, 128 KB Flash","metaDescription":"MSP430F6745AIPEU 16-bit MCU with 25 MHz core, 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":"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":"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":"$9.7272","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/87bbda703b256feee860450caa184c15.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to MSP430F6745AIPEU?","answer":"Within the MSP430F6xx family, the MSP430F6745IPEU (without the 'A' suffix) shares the same 128-LQFP footprint and peripheral set — the difference is typically a minor revision or errata fix.
