On the connectivity side it carries I²C, SPI, UART/USART, LINbus, and IrDA interfaces, plus 62 general-purpose I/O lines. ## The sigma-delta ADC — why this chip exists The four 24-bit sigma-delta converters are the reason TI built this variant. They are not general-purpose SAR converters bolted on as an afterthought; the modulator architecture and digital filter are tuned for 50/60 Hz line-cycle synchronous sampling, harmonic analysis, and active/reactive energy accumulation. For a design engineer sizing a three-phase meter or a submetering node, the 4x24b SD ADC means you can digitize voltage and current from all three phases plus neutral in one chip, without an external analog front-end. The 8x10-bit auxiliary ADC handles the less demanding housekeeping measurements — temperature, DC bus voltage, tamper detection. Internal oscillator is available, but for revenue-grade accuracy you will clock it from an external crystal and let the FLL lock to the line frequency. ## Package and footprint reality Housed in a 100-pin LQFP with a 14x14 mm body (supplier device package 100-LQFP 14x14). Surface-mount only. The 0.5 mm pitch and exposed pad demand a decent solder stencil aperture and a reflow profile that hits the datasheet's peak temperature window — MSL level is not listed here, but standard LQFP practice is MSL 3, so bake before reflow if the moisture-barrier bag has been breached. No thermal pad on this package; the 100-LQFP dissipates through the leads and the board copper. ## Active lifecycle — no LTB concern TI lists the MSP430F67481IPZ as Active. For a BOM cost engineer or supply-chain planner, this removes the single-source risk that haunts older MSP430 derivatives. The base product number is MSP430F67481, so any future die shrinks or package changes will carry a suffix revision, not a sudden obsoletion. If you need a second-source conversation, there is no pin-compatible drop-in from another vendor — the sigma-delta ADC peripheral is TI-specific — but within the MSP430F6xx family, density and peripheral variants share the same LQFP-100 footprint.","metaTitle":"TI MSP430F67481IPZ 16-Bit MCU, 25 MHz, 512KB Flash","metaDescription":"Texas Instruments MSP430F67481IPZ 16-bit MCU with MSP430 CPUXV2 core, 25 MHz speed, 512KB Flash, 16K x 8 RAM, 4x24b sigma-delta ADC, 100-LQFP.","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":"62","Core Processor":"MSP430 CPUXV2","Package / Case":"100-LQFP","Product Status":"Active","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F67481","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$14.2240","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9e5a6f46316bab53467cc83d35695a88.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the equivalent of MSP430F67481IPZ?","answer":"There is no pin-compatible second-source equivalent from another manufacturer for this part — the four-channel 24-bit sigma-delta ADC peripheral is TI-proprietary.
