The distinguishing feature is the dual ADC block: three 24-bit sigma-delta converters paired with eight 10-bit successive-approximation channels, allowing simultaneous high-resolution current/voltage sensing and auxiliary monitoring on a single chip. ## Obsolete — what that means for procurement The MSP430F6731IPZ carries an obsolete lifecycle status. Texas Instruments has discontinued this specific package variant (100-LQFP), and no last-time-buy window is indicated in the available records. Any new design should migrate to a current-production MSP430F6xx variant or a pin-compatible alternative within the family. ## Peripheral set and connectivity On-chip peripherals include a brown-out detect and reset, DMA controller, LCD driver, power-on reset, PWM timer, and watchdog timer. With 72 general-purpose I/O lines in the 100-LQFP package, the device can handle a segmented LCD display, multiple sensor inputs, and a communication backhaul without external port expanders. ## Package and mounting considerations The MSP430F6731IPZ is supplied in a 100-pin LQFP package with a 14x14 mm body (100-LQFP). It is a surface-mount device intended for reflow soldering.","metaTitle":"MSP430F6731IPZ 16-bit MCU, 25 MHz, 32 KB Flash, 100-LQFP","metaDescription":"Texas Instruments MSP430F6731IPZ 16-bit MCU with 25 MHz CPUXV2 core, 32 KB Flash, 2K x 8 RAM, dual ADC (8x10b + 3x24b), industrial temp -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"25MHz","Series":"MSP430F6xx","Package":"Tray","RAM Size":"2K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, LCD, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"72","Core Processor":"MSP430 CPUXV2","Package / Case":"100-LQFP","Product Status":"Obsolete","Data Converters":"A/D 8x10b, 3x24b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F6731","Program Memory Size":"32KB (32K 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":"$4.1800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4d6497d44b37ad9be23ad8aca111200b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for MSP430F6731IPZ?","answer":"For a pin-compatible alternative within the MSP430F6xx family, the MSP430F6732IPZ is a close sibling — it shares the same 100-LQFP footprint and peripheral set but offers additional Flash or RAM.
