FRAM writes at bus speed with essentially unlimited endurance — no write-cycle budget to manage, no erase-before-write penalty. ## Peripherals and I/O The part brings 33 I/O lines, a 14-channel 12-bit ADC, and serial connectivity covering I²C, SPI, UART, and IrDA. On-chip peripherals include a brown-out reset, POR, DMA, PWM, and a watchdog timer. ## Lifecycle and sourcing No last-time-buy notice or phase-out has been issued.","metaTitle":"TI MSP430FR5947IRHAR 16-bit MCU, 32KB FRAM, 16MHz, 40-VQFN","metaDescription":"Texas Instruments MSP430FR5947IRHAR 16-bit MCU with 32KB FRAM, 16MHz CPU, 1.8V–3.6V supply, industrial temp range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"16MHz","Series":"MSP430™ FRAM","Package":"Tape & Reel (TR)","RAM Size":"1K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"33","Core Processor":"MSP430 CPUXV2","Package / Case":"40-VFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 14x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR5947","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"40-VQFN (6x6)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.5584","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8b4ff231ab172f4b122f04a9e54765b3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the pin-compatible alternatives to MSP430FR5947IRHAR?","answer":"Within the MSP430FR5947 family, the base product number MSP430FR5947 covers multiple density and peripheral options.
