The MSP430 CPUXV2 is a 16-bit RISC core rated for 25 MHz operation. At that clock, a single-cycle multiply-accumulate runs in 40 ns, which keeps sensor fusion loops or PID updates inside a 100 µs control period without needing a DMA assist. ## 8 KB Flash: firmware footprint reality Program memory is 8 KB of Flash (8K x 8). That is a comfortable fit for a single-purpose controller — a BLDC motor commutation loop, a temperature sensor node with Modbus RTU, or a keypad scanner with I²C display. It will not hold a full Bluetooth stack or a file system. The Flash is field-reprogrammable via the internal bootloader or a debugger, so firmware updates are possible without a dedicated programmer. ## 40-DSBGA: footprint and layout considerations Housed in a 40-ball DSBGA (0.4 mm pitch typical for this class), the MSP430F5131IYFFT saves board area but demands a controlled solder-paste stencil and X-ray inspection after reflow. The 31 I/O lines are accessible through the BGA balls — enough for a parallel LCD bus, a row-column key matrix, and a couple of serial peripherals. Supply decoupling should follow the recommended 0.1 µF per Vcc ball pair, placed directly under the package on the opposite side of the board. ## Industrial temperature and peripheral mix The peripheral set includes brown-out detect, POR, PWM, WDT, and a DMA controller — plus I²C, IrDA, SCI, SPI, and UART/USART connectivity. The wide range also lets the MCU run directly from a Li-ion cell (3.0 V to 4.2 V) without a series regulator, though the 1.8 V minimum means a boost converter is needed if the battery drops below that threshold. Quiescent current is not specified in the listing, but the MSP430 family is known for sub-1 µA standby modes — expect similar here with careful clock gating.","metaTitle":"TI MSP430F5131IYFFT 16-bit MCU, 25MHz, 8KB Flash, 40-DSBGA","metaDescription":"Texas Instruments MSP430F5131IYFFT 16-bit MCU with MSP430 CPUXV2 core, 25MHz speed, 8KB Flash, 1KB RAM, 31 I/O, I²C/SPI/UART, -40°C to 85°C, 40-DSBGA.","metaKeywords":null},"attributes":{"series":"MSP430F5xx","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"25MHz","Series":"MSP430F5xx","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"1K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"31","Core Processor":"MSP430 CPUXV2","Package / Case":"40-UFBGA, DSBGA","Product Status":"Active","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F5131","Program Memory Size":"8KB (8K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"40-DSBGA","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.8500","priceTiers":[{"qty":1,"price":"$3.85000","currency":"USD"},{"qty":10,"price":"$3.45600","currency":"USD"},{"qty":25,"price":"$3.26720","currency":"USD"},{"qty":100,"price":"$2.83140","currency":"USD"},{"qty":250,"price":"$2.68620","currency":"USD"},{"qty":500,"price":"$2.41032","currency":"USD"},{"qty":1250,"price":"$2.03280","currency":"USD"},{"qty":2500,"price":"$1.93116","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/b98422c63ee233cf7bbc58756d636008.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F5131IYFFT/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between MSP430F5131IYFFT and MSP430F5131IYFFR?","answer":"The suffix T vs R typically indicates tape-and-reel packaging variant differences — the T variant is often a standard reel quantity while R may denote a smaller reel or different tape orientation.
