That matters for applications that log data frequently — think utility meters or event recorders — because FRAM endurance is orders of magnitude higher than Flash, and the unified memory map means you do not partition code and data. The 2K x 8 RAM handles stack and scratchpad; the FRAM holds both program and persistent variables. For BOM lines that already specify this exact MCU, the only channel is the independent surplus and new-old-stock market.","metaTitle":"TI MSP430FR6977IPZR 16-bit MCU, 64 KB FRAM, 16 MHz, 100-LQFP","metaDescription":"Texas Instruments MSP430FR6977IPZR 16-bit MCU with 64 KB FRAM, 16 MHz CPU, 63 I/O, LCD driver, industrial temp -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"16MHz","Series":"MSP430™ FRAM","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, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"63","Core Processor":"MSP430 CPUXV2","Package / Case":"100-LQFP","Product Status":"Obsolete","Data Converters":"A/D 16x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR6977","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FRAM","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":"$5.5429","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/84e9358863d9bf629dfd6367dc886fd0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430FR6977IPZR/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for MSP430FR6977IPZR?","answer":"No official replacement order code is listed.
