This makes it a strong fit for applications that log data frequently or need field-reprogrammable firmware without wearing out the memory: smart meters, building automation panels, portable medical instruments, and sensor nodes that wake briefly to sample and log then return to sleep. The 80-LQFP package (12x12 mm body) brings out 63 general-purpose I/O lines, plus a segment LCD controller that can drive a glass display directly, saving a separate display driver IC. If your design lives in a conditioned server room or consumer appliance, the margin is generous; if it goes into a hot motor-drive cabinet, verify that the 85°C ceiling leaves enough headroom above the internal ambient. ## Integrated peripherals reduce external component count This part packs a 12-channel 12-bit ADC, a real-time clock with watchdog timer, a brown-out reset circuit, and a DMA controller that can move data between peripherals and FRAM without CPU intervention. The LCD driver supports up to 320 segments (common for 8-digit numeric displays or custom icon panels), which eliminates a separate COG display driver from the bill of materials. For BOM planning, there is no last-time-buy pressure on this line.","metaTitle":"TI MSP430FR6979IPN 16-bit MCU, 128KB FRAM, 16MHz, 80-LQFP","metaDescription":"Texas Instruments MSP430FR6979IPN 16-bit MCU with 128KB FRAM, 16MHz core, 63 I/O, LCD driver, -40 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":"16MHz","Series":"MSP430™ FRAM","Package":"Tube","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":"80-LQFP","Product Status":"Active","Data Converters":"A/D 12x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR6979","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"80-LQFP (12x12)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.2581","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/84e9358863d9bf629dfd6367dc886fd0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430FR6979IPN/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to the MSP430FR6979IPN in the MSP430 FRAM family?","answer":"Within the MSP430 FRAM series, the MSP430FR6979IPN is a specific density and peripheral variant. Pin-compatible siblings in the same 80-LQFP footprint include parts with different FRAM sizes (e.g., 64 KB or 256 KB) and slightly different peripheral sets. Check the TI MSP430 FRAM cross-reference guide for the exact memory and feature trade-off that matches your firmware size — the package and pinout are consistent across the family for the same package code."},{"question":"What compliance documentation does TI provide for the MSP430FR6979IPN?","answer":"Texas Instruments provides RoHS and REACH compliance declarations, material composition data, and a conflict minerals report for this part. The 80-LQFP package is lead-free (RoHS compliant) per TI's standard green packaging. No UL or IEC certification is listed for this component; those are typically system-level certifications, not IC-level."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430FR6979IPN","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430FR6979IPN when reusing this data.
