No erase-before-write, no sector boundaries to manage, no wear-leveling needed for typical data-logging or config-storage duty. The 8K x 8 of SRAM handles stack and scratchpad, and the 16-channel 12-bit ADC covers analog inputs without an external converter. ## Industrial temperature, wide supply — where it fits The 1.8V to 3.6V supply range means a single Li-ion cell or a regulated 3.3V rail both work without a secondary regulator. The 48-VQFN (7x7) package with exposed pad needs a thermal via stitch under the paddle if you push continuous current through the I/O banks — the pad is the primary heat path. ## Peripherals and connectivity for a sensor-hub role The PWM timer can drive a small motor or LED string directly. For serial links you get I2C, SPI, and UART/USART — enough to talk to a radio module, an external sensor array, or a display controller. IrDA support is there if the design needs infrared communication. The base product number is MSP430FR59941, so any variant suffix differences are package or tape/reel options, not functional changes.","metaTitle":"MSP430FR59941IRGZT 16-bit MCU, 256KB FRAM, 16MHz, 48-VQFN","metaDescription":"Texas Instruments MSP430FR59941IRGZT 16-bit MCU with 256KB FRAM, 8K x 8 RAM, 16MHz CPUXV2 core, 40 I/O, 12-bit ADC, I2C/SPI/UART, -40 to 85°C, 48-VQFN.","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","RAM Size":"8K x 8","Core Size":"16-Bit","Packaging":"Tape & Reel (TR) Cut Tape (CT)","EEPROM Size":"-","Part Status":"Active","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I2C, IrDA, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"40","Core Processor":"MSP430 CPUXV2","Package / Case":"48-VFQFN Exposed Pad","Data Converters":"A/D 16x12b","Oscillator Type":"External, Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR59941","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"48-VQFN (7x7)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.1800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3df845120280d5185632d76e74561d12.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between MSP430FR59941IRGZT and MSP430FR5994IRGZT?","answer":"The two part numbers share the same base die and package. The difference is in the FRAM and SRAM density options across the MSP430FR5994 family — the '41' variant carries 256KB FRAM and 8K x 8 SRAM, while the '4' variant (no '1') has a different memory configuration. Pin-compatible across the family, so a BOM swap is a firmware recompile, not a board respin."},{"question":"Is the MSP430FR59941IRGZT compatible with 3.3V logic?","answer":"Yes. The supply range goes up to 3.6V, so 3.3V logic levels are within spec. The I/O pins are 5V-tolerant? — the evidence does not state a 5V tolerance, so assume 3.3V-only on the I/O rails."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430FR59941IRGZT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430FR59941IRGZT when reusing this data.
