That makes this part a fit for data-logging, metering, and battery-operated edge nodes where frequent nonvolatile writes or instant-on wake from deep sleep matters. The 20-channel 12-bit ADC, hardware multiplier, and DMA engine handle sensor aggregation without loading the core. ## Supply, temperature, and the 87-ball BGA footprint Package is an 87-ball NFBGA measuring 6 mm × 6 mm — fine-pitch BGA with 0.5 mm or 0.65 mm ball pitch depending on the specific die revision. That footprint needs a controlled-impedance fanout pattern and a stencil matched to the ball diameter; don't assume a generic BGA escape works without checking the TI recommended land pattern. ## Peripherals and debug reality 68 GPIOs, I²C, SPI, UART/USART, plus IrDA for optical links. Brown-out detect, POR, and watchdog are on-chip — no external supervisor needed for basic safety. The CPUXV2 core has a single-cycle 32-bit hardware multiplier and a 3-stage pipeline; at 16 MHz it delivers about 16 MIPS. Debug is via the standard Spy-Bi-Wire (SBW) two-pin JTAG interface. MSP430Flasher works with this device as long as the toolchain version supports the FR59xx family — check the release notes for the specific FRAM controller revision. The base product number MSP430FR59941 covers a density and feature set that TI continues to support. For a dual-sourcing review, the MSP430FR5994 (without the trailing '1') is the same die in a different test-program variant — verify pin compatibility against the TI cross-reference before swapping.","metaTitle":"TI MSP430FR59941IZVWR 16-bit MCU, 256KB FRAM, 16MHz, 87-BGA","metaDescription":"Texas Instruments MSP430FR59941IZVWR 16-bit MCU with 256KB FRAM, 8KB RAM, 16MHz CPUXV2 core, 68 I/O, 20x12-bit ADC, 1.8-3.6V, -40 to 85°C, 87-NFBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"16MHz","title":"MSP430FR59941IZVWR","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":"68","Core Processor":"MSP430 CPUXV2","Package / Case":"87-VFBGA","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":"87-NFBGA (6x6)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.3423","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3df845120280d5185632d76e74561d12.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430FR59941IZVWR/alternatives.json"},"ai":{"faq":[{"question":"Is MSP430FR59941IZVWR compatible with MSP430FR5994?","answer":"MSP430FR5994 is the same base die in a different test-program variant.
