No wear-leveling in firmware; you can log data or update code over the air without worrying about sector endurance. The 1K x 8 RAM handles stack and scratchpad for the 8 MHz core. ## Industrial temp and supply — fits battery or line-powered gear Supply range is 2V to 3.6V — a single Li-ion cell or two alkaline cells powers it directly. The internal oscillator (no external crystal needed for many applications) and the brown-out reset keep things stable during power-up and dropouts. ## Peripherals and I/O — enough for a sensor hub or control node 32 I/O lines give you room for a keypad, LED indicators, and sensor interrupts. The 14-channel 10-bit ADC handles analog inputs like thermistors or potentiometers. Connectivity includes I²C, SPI, UART, plus LIN and IrDA — useful for automotive body modules or industrial sensor buses. PWM and watchdog timer are on board. Comes in a 40-VFQFN with exposed pad (6x6 mm body). The pad needs a thermal via stitch under it if you push continuous current or run near 85°C ambient. Surface-mount only — no socket option for field swaps without hot air. ## Lifecycle status TI lists this part as active. It is a current-production device safe to specify into a new BOM.","metaTitle":"MSP430FR5729IRHAR 16-bit MCU, 8 MHz, 16 KB FRAM, 40-VQFN","metaDescription":"TI MSP430FR5729IRHAR 16-bit MCU with 8 MHz core, 16 KB FRAM, 1K x 8 RAM, 32 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":"32","Core Processor":"MSP430 CPUXV2","Package / Case":"40-VFQFN Exposed Pad","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":"40-VQFN (6x6)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.4800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ba48b44d539c33888f039fd055fc3f10.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430FR5729IRHAR/alternatives.json"},"ai":{"faq":[{"question":"Is MSP430FR5729IRHAR obsolete or active?","answer":"Active."},{"question":"What are the alternatives to MSP430FR5729IRHAR?","answer":"Within the MSP430 FRAM family, pin-compatible siblings with different FRAM sizes exist — for example, the MSP430FR5720 with 8 KB FRAM or the MSP430FR5739 with 24 KB FRAM.
