That makes it a strong fit for metering, data-logging, and battery-powered instrumentation where you need to keep calibration constants or a transaction log without wearing out EEPROM. The 8 KB of SRAM handles stack and scratchpad. It comes in an 80-LQFP package with 68 I/O, so you get enough pins for a parallel LCD or a sensor array without going to a BGA. ## Industrial temp, wide supply — fits a lot of boards The built-in brown-out detect and POR keep the FRAM contents from corrupting on a glitchy power-down — important because FRAM doesn't need a save-to-Flash step, but it also doesn't have the write-protect inertia of Flash. ## Peripherals and connectivity There's a 20-channel 12-bit ADC on-chip, so you can sample analog signals without an external converter. PWM channels support motor control and LED dimming. DMA moves data between peripherals and memory without CPU intervention, which matters when you are running the core at 16 MHz and don't want to waste cycles on byte-by-byte transfers. ## Active lifecycle — no LTB panic The base product number is MSP430FR59941, so if you need a different package or temperature grade, the family has options — but this 80-LQFP industrial-temp variant is the one most design-ins land on.","metaTitle":"TI MSP430FR59941IPNR 16-bit MCU, 16 MHz, 256 KB FRAM","metaDescription":"Texas Instruments MSP430FR59941IPNR 16-bit MCU with 16 MHz CPU, 256 KB FRAM, 8 KB RAM, 68 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)","RAM Size":"8K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"68","Core Processor":"MSP430 CPUXV2","Package / Case":"80-LQFP","Product Status":"Active","Data Converters":"A/D 20x12b","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":"80-LQFP (12x12)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.3423","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3df845120280d5185632d76e74561d12.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum clock speed of MSP430FR59941IPNR?","answer":"The core processor runs at 16 MHz. That is the maximum clock speed for this device — no PLL multiplier to push it higher. At 16 MHz the FRAM delivers single-cycle access with no wait states, so the effective throughput is close to the clock rate for most code."},{"question":"What is the closest pin-compatible alternative in the MSP430 FRAM family?","answer":"Within the MSP430FR59941 base number, the main variants differ by package and temperature range. The 80-LQFP industrial-temp version is the most common. If you need a wider temperature range or a smaller package, check the MSP430FR5994 family table — but for a drop-in replacement on the same PCB footprint, stick with the same 80-LQFP package code."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430FR59941IPNR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430FR59941IPNR when reusing this data.
