That eliminates the erase-before-write overhead of Flash and makes field-update or data-logging firmware practical without wear-leveling. The 8 KB of SRAM handles stack and runtime variables. The 16 MHz clock rate is typical for this ultra-low-power family; the CPUXV2 pipeline keeps throughput efficient at that speed. Brown-out detect and POR are integrated, reducing external supervisor circuitry. ## 54 I/O and peripheral set in a 64-LQFP The 64-pin LQFP (10x10 mm body) exposes 54 general-purpose I/O lines. The oscillator can be driven from an external crystal or the internal RC. For PCB layout, the 0.5 mm pitch LQFP requires standard surface-mount assembly; no thermal pad or exposed paddle to manage. TI lists this part as Active. For dual-source planning, the MSP430FR59941 family includes pin-compatible density variants; the exact alternate depends on your memory and I/O requirements.","metaTitle":"TI MSP430FR59941IPMR 16-bit MCU, 16MHz, 256KB FRAM, 64-LQFP","metaDescription":"Texas Instruments MSP430FR59941IPMR: 16-bit MCU, 16MHz CPUXV2, 256KB FRAM, 8KB RAM, 54 I/O, 1.8V-3.6V, -40°C to 85°C, 64-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"16MHz","title":"MSP430FR59941IPMR","Series":"MSP430™ FRAM","Package":"Tape & Reel (TR)","RAM Size":"8K x 8","Core Size":"16-Bit","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"54","Core Processor":"MSP430 CPUXV2","Package / Case":"64-LQFP","Data Converters":"A/D 17x12b","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":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.2791","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3df845120280d5185632d76e74561d12.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between MSP430FR59941IPMR and MSP430FR59941IPM?","answer":"The IPMR suffix indicates Tape & Reel packaging; the IPM suffix typically indicates tube or tray.
