For a firmware-update strategy or data-logging application, this eliminates the wear-leveling and sector-management overhead that Flash-based MCUs require. The 512 x 8 SRAM supports a small stack and variable workspace; the 44 I/O lines include a segment LCD driver, making this a natural fit for metering, portable instrumentation, and human-machine-interface panels where the display is a segment LCD rather than a graphics panel.","metaTitle":"MSP430FR4131IG48R 16-bit MCU, 16 MHz, 4.5 KB FRAM, 48-TSSOP","metaDescription":"Texas Instruments MSP430FR4131IG48R 16-bit MCU with 16 MHz core, 4.5 KB FRAM, 512 B SRAM, 44 I/O, LCD driver, 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":"16MHz","Series":"MSP430™ FRAM","Package":"Tape & Reel (TR)","RAM Size":"512 x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, LCD, POR, PWM, WDT","Connectivity":"I²C, IrDA, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"44","Core Processor":"MSP430 CPU16","Package / Case":"48-TFSOP (0.240\\\", 6.10mm Width)","Product Status":"Active","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR4131","Program Memory Size":"4.5KB (4.5K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"48-TSSOP","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1810","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/dbbf23a4e60ee594de5e0dd102bb2969.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is FRAM in MSP430 microcontrollers?","answer":"FRAM (Ferroelectric Random Access Memory) is a non-volatile memory technology used in place of Flash. It offers much higher write endurance (10^15 cycles), faster write speeds (no erase needed), and lower write power. In the MSP430FR4131IG48R, the 4.5 KB program memory is FRAM, which simplifies firmware update handling and extends the product's useful life in data-intensive applications."},{"question":"What is the closest pin-compatible alternative to MSP430FR4131IG48R?","answer":"Within the MSP430FR413x family, parts with the same 48-TSSOP package and pinout differ primarily in FRAM and SRAM size. The MSP430FR4132 and MSP430FR4133 offer larger memory options while remaining footprint-compatible. For an exact pin-compatible drop-in with the same peripheral set, check the base product number MSP430FR4131 — the IG48R suffix denotes the 48-TSSOP package and Tape & Reel. No exact second-source from another manufacturer exists for this specific order code."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430FR4131IG48R","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430FR4131IG48R when reusing this data.
