The eight 10-bit ADCs handle auxiliary channels like temperature or tamper detection. The 72 I/O pins give plenty of headroom for driving a segment LCD, reading keypads, and communicating with a host system over I²C or SPI. ## Package and footprint notes for the layout engineer The MSP430F6731IPZR comes in a 100-pin LQFP with a 14x14 mm body (0.5 mm pitch). It is a surface-mount package that reflows with standard lead-free profiles. Supply decoupling should follow the typical 0.1 µF + 1 µF per Vcc pin pair.","metaTitle":"MSP430F6731IPZR Texas Instruments 16-bit MCU, 25 MHz","metaDescription":"MSP430F6731IPZR 16-bit MCU with 25 MHz CPUXV2 core, 32 KB Flash, 2K x 8 RAM, dual ADC (8x10b + 3x24b), 72 I/O.","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":"Tape & Reel (TR)","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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4d6497d44b37ad9be23ad8aca111200b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F6731IPZR/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for MSP430F6731IPZR?","answer":"Texas Instruments has not published an official direct replacement for the MSP430F6731IPZR.
