The 512 x 8 RAM handles the stack and scratchpad. Running at 16 MHz from an internal oscillator, this MCU draws the characteristic MSP430 sub-milliamp active current, though the exact figure depends on the clock tree configuration and peripheral load. ## Integrated LCD controller — one less chip on the BOM A standout peripheral is the integrated LCD driver, which can directly drive a segment LCD panel without an external display controller IC. For a blood-glucose meter, thermostat, or gas-pump display, that saves board space, reduces BOM cost, and simplifies the firmware — the MSP430's LCD module handles the multiplex timing and contrast control in hardware. The 44 general-purpose I/O pins, many of which double as LCD segment or common outputs, give you flexibility to lay out the display traces without fighting the pinout. The 48-TSSOP package (0.240\" body width, 6.10 mm) is a fine-pitch surface-mount footprint that routes easily on a two-layer board. The 0.5 mm lead pitch demands careful solder-paste stencil design, but it is a standard package for this I/O count. ## Peripheral set for sensor-heavy designs The 8-channel 10-bit ADC is adequate for reading thermistors, potentiometers, or simple analog sensors; if you need higher resolution, an external delta-sigma ADC over I²C is the usual pairing. The brown-out detect and POR circuits mean you can skip an external supervisor IC in many designs, as long as the supply ramp meets the datasheet timing. Brown-out reset and the watchdog timer are both present, so a basic safety-net architecture is built in. For a new product introduction, this part does not carry the supply-chain risk of an NRND or obsolete device. The base product number MSP430FR4131 covers a family of density and package variants, so if a future revision needs more memory or a different footprint, there is a migration path within the same family without a complete firmware rewrite. No special handling or exemption paperwork is needed for shipping into regulated markets.","metaTitle":"TI MSP430FR4131IG48 16-bit MCU, 4.5KB FRAM, 16MHz, 48-TSSOP","metaDescription":"Texas Instruments MSP430FR4131IG48 16-bit MCU with 4.5KB FRAM, 16MHz CPU, integrated LCD controller, 44 I/O, 1.8V-3.6V, -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":"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":"$2.9600","priceTiers":[{"qty":1,"price":"$2.96000","currency":"USD"},{"qty":10,"price":"$2.66200","currency":"USD"},{"qty":25,"price":"$2.51120","currency":"USD"},{"qty":100,"price":"$2.13940","currency":"USD"},{"qty":250,"price":"$2.00880","currency":"USD"},{"qty":500,"price":"$1.75770","currency":"USD"},{"qty":1000,"price":"$1.45638","currency":"USD"},{"qty":2500,"price":"$1.35594","currency":"USD"},{"qty":5000,"price":"$1.30572","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/dbbf23a4e60ee594de5e0dd102bb2969.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430FR4131IG48/alternatives.json"},"ai":{"faq":[{"question":"What is the FRAM size of MSP430FR4131IG48?","answer":"The MSP430FR4131IG48 has 4.5 KB of FRAM program memory (4.5K x 8) and 512 bytes of SRAM (512 x 8).
