Unlike Flash, FRAM writes at bus speed — no erase-before-write, no sector-erase latency, and no 100k-cycle endurance ceiling. For a firmware engineer, this means you can treat the program memory as a unified code-and-data space: store calibration constants, configuration tables, or a rolling data log in the same array as the executable, and update individual bytes in a single store instruction. The 512 x 8 RAM handles stack and scratchpad; the FRAM handles persistent storage. No external serial EEPROM needed for most designs, which saves a BOM line and a board footprint. ## Peripheral integration for human-machine interface and sensor fusion The on-chip LCD driver can directly drive a segmented glass LCD — common in meter and thermostat displays — without an external display controller. The 8-channel 10-bit ADC reads analog sensors (temperature, pressure, battery voltage), while the I²C and SPI buses connect to digital sensors or radios. The brown-out detect and POR circuits reset the MCU cleanly on supply droop, which is critical for battery-powered equipment that may see a cold-crank dip. The 52 I/O pins in the 56-TSSOP package leave plenty of headroom for a membrane keypad or additional discrete signals. The 16 MHz CPU speed is enough for a control loop sampling sensors at a few kilohertz and updating a display — not for heavy DSP, but adequate for the metering and HMI class this part targets. It is ROHS3 compliant.","metaTitle":"TI MSP430FR4131IG56 16-bit MCU, 4.5KB FRAM, 16MHz, 56-TSSOP","metaDescription":"Texas Instruments MSP430FR4131IG56 16-bit MCU with 4.5KB FRAM, 16MHz CPU, 512B RAM, LCD driver, I²C/SPI/UART, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"MSP430™ FRAM","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"16MHz","Series":"MSP430™ FRAM","Package":"Tube","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":"52","Core Processor":"MSP430 CPU16","Package / Case":"56-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":"56-TSSOP","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.2900","priceTiers":[{"qty":1,"price":"$2.29000","currency":"USD"},{"qty":10,"price":"$2.06100","currency":"USD"},{"qty":25,"price":"$1.94400","currency":"USD"},{"qty":100,"price":"$1.65630","currency":"USD"},{"qty":250,"price":"$1.55520","currency":"USD"},{"qty":500,"price":"$1.36080","currency":"USD"},{"qty":1000,"price":"$1.12752","currency":"USD"},{"qty":2500,"price":"$1.04976","currency":"USD"},{"qty":5000,"price":"$1.01088","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/dbbf23a4e60ee594de5e0dd102bb2969.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430FR4131IG56/alternatives.json"},"ai":{"faq":[{"question":"What is the equivalent of MSP430FR4131IG56?","answer":"The MSP430FR4131IG48 is the same base device in a different package variant — the IG56 is a 56-TSSOP, while the IG48 is a 48-pin package.
