On-chip peripherals include a 12-bit ADC with 12 channels, brown-out detect, POR, PWM, DMA, and a watchdog timer, plus I²C, SPI, and UART serial interfaces. The 38-TSSOP package gives you 31 I/O lines in a compact surface-mount footprint. ## FRAM memory — why it matters for the BOM FRAM writes at bus speed with no erase cycle, consumes a fraction of the energy of Flash per write, and endures over 10¹⁵ write cycles. For designs that log data, store calibration constants, or update firmware in the field, this eliminates the complexity of wear-leveling and the power penalty of Flash page-erase. The 1K x 8 SRAM provides scratchpad and stack space adequate for control loops and moderate data buffering. ## Lifecycle and sourcing posture TI lists the MSP430FR5947IDA as Active. That means no last-time-buy risk and full manufacturer support for new designs. For volume production, the 38-TSSOP package is a standard, widely sourced footprint.","metaTitle":"Texas Instruments MSP430FR5947IDA 16-bit MCU, 16MHz","metaDescription":"MSP430FR5947IDA 16-bit MCU with 16MHz core, 32KB FRAM, 1K x 8 SRAM, 12-bit ADC, I²C/SPI/UART, -40°C to 85°C, 1.8V-3.6V.","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":"Tube","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":"31","Core Processor":"MSP430 CPUXV2","Package / Case":"38-TSSOP (0.240\\\", 6.10mm Width)","Product Status":"Active","Data Converters":"A/D 12x12b","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":"38-TSSOP","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.2447","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8b4ff231ab172f4b122f04a9e54765b3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the best alternatives or replacements for the MSP430FR5947IDA?","answer":"Within the MSP430 FRAM family, pin-compatible options with different FRAM and SRAM densities exist (e.g., the MSP430FR5949 with 64 KB FRAM).
