This combination targets designs that need to digitise multiple analog channels (voltage and current sense from a power grid or sensor array) and drive a local LCD panel directly, all while keeping the BOM count low. The 25 MHz CPU clock is the throughput ceiling for this MSP430. For a polyphase metrology application running a 24-bit sigma-delta conversion loop, the 25 MHz rate gives enough MIPS to compute active/reactive power, harmonics, and RMS values in software while still servicing the LCD refresh and a UART or SPI communication link. If the design needs a faster control loop or software-based FFT at higher bin counts, the 25 MHz ceiling is the constraint to budget against. ## Four 24-bit sigma-delta ADCs and LCD drive — the integration win The MSP430F67471AIPEU packs four independent 24-bit sigma-delta ADCs, each with its own programmable gain amplifier and digital filter. This is the peripheral that saves a separate analog front-end IC in a three-phase energy meter or a multi-channel sensor hub. The LCD controller drives a segmented display directly, eliminating a separate display driver chip. The part also includes a brown-out detect, POR, PWM timers, and a watchdog timer — the usual supervisory peripherals for an industrial or instrumentation design. ## Connectivity and I/O for a mixed-signal system The I²C and SPI interfaces can operate simultaneously — the peripheral set is independent, so a sensor read over SPI does not block a display update or a calibration command over I²C. ## Package and temperature grade for the intended environment Housed in a 128-pin LQFP (20x14 mm body), the MSP430F67471AIPEU is a surface-mount part suitable for automated assembly.","metaTitle":"MSP430F67471AIPEU MCU, 16-bit, 25 MHz, 256 KB Flash","metaDescription":"Texas Instruments MSP430F67471AIPEU 16-bit MCU with 25 MHz CPU, 256 KB Flash, 32 KB RAM, 4x24-bit sigma-delta ADC, LCD driver.","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":"32K 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":"MSP430F67471","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/94013ff2fb2ad301a731e282d067c425.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between MSP430F67471AIPEU and MSP430F67371AIPEU?","answer":"The key difference is the analog peripheral count: the MSP430F67471AIPEU integrates four 24-bit sigma-delta ADCs, while the MSP430F67371AIPEU integrates three.
