Runs on 2V to 3.6V, so a single 3.3V or 3.0V lithium cell works fine. Not rated for under-hood or downhole, but fine for most commercial and industrial enclosures. Lifecycle status is Active per TI's product bulletin. No last-time-buy notice, no end-of-life window.","metaTitle":"TI MSP430FR5729IDAR 16-bit MCU, 8MHz, 16KB FRAM, 38-TSSOP","metaDescription":"Texas Instruments MSP430FR5729IDAR 16-bit MCU with 8MHz core, 16KB FRAM program memory, 1K x 8 RAM, 30 I/O, industrial temp -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"8MHz","Series":"MSP430™ FRAM","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"1K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"30","Core Processor":"MSP430 CPUXV2","Package / Case":"38-TSSOP (0.240\\\", 6.10mm Width)","Product Status":"Active","Data Converters":"A/D 14x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR5729","Program Memory Size":"16KB (16K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"38-TSSOP","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1833","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ba48b44d539c33888f039fd055fc3f10.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430FR5729IDAR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between MSP430FR5729 and MSP430FR5739?","answer":"The MSP430FR5739 steps up to 24KB FRAM and 2K x 8 RAM, versus 16KB FRAM and 1K x 8 RAM on the FR5729.
