For a 3.75 KB program space, that means you can treat the FRAM as unified memory: code, constant tables, and a small data-logging buffer all live in the same address space without sector-erase delays or wear-leveling schemes. The 1 KB RAM handles stack and temporary variables; the split means a firmware engineer needs to budget carefully for interrupt nesting and buffer sizes, but the FRAM write speed (comparable to SRAM) eliminates the store-to-Flash latency that complicates real-time logging. ## Industrial temp range and wide supply — one rail for the sensor node The industrial temperature grade covers outdoor telecom cabinets, engine-bay-adjacent sensors, and factory-floor controllers. ## 16-VFQFN with exposed pad — layout checklist Without that via stitch, the junction temperature rises faster under continuous load — the pad is the primary heat path. The 12 I/O pins are all on the periphery; no centre pins to route. For a BOM line, this is a green light for new product introduction without planning a second-source qualification window.","metaTitle":"TI MSP430FR2311IRGYT 16-bit MCU, 16 MHz, 3.75 KB FRAM","metaDescription":"Texas Instruments MSP430FR2311IRGYT 16-bit MCU with 16 MHz core, 3.75 KB FRAM, 1 KB RAM, 12 I/O, 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); Cut Tape (CT)","RAM Size":"1K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, IrDA, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"12","Core Processor":"MSP430 CPU16","Package / Case":"16-VFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR2311","Program Memory Size":"3.75KB (3.75K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"16-VQFN (4x3.5)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.6700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f54bef595f6c353e931fcbdbed65c27e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between MSP430FR2311IRGYT and MSP430FR2313?","answer":"The MSP430FR2313 is a higher-density sibling in the same FRAM family, typically offering more program memory and RAM.
