On-chip SRAM is 2K x 8. The part integrates a 12-bit ADC with 16 multiplexed channels, a brown-out detect/reset, POR, DMA, PWM, and a watchdog timer. Connectivity covers I²C, IrDA, SCI, SPI, and UART/USART. ## FRAM vs Flash: why the memory type matters for the BOM The 64 KB FRAM program memory is the headline differentiator in this MSP430. FRAM writes at full bus speed without a page-erase cycle, so firmware updates over I²C or SPI complete in milliseconds rather than seconds. Standby current is lower than equivalently sized Flash because FRAM retains data without a charge pump. For designs that log data or store calibration constants, FRAM eliminates a separate serial EEPROM — a BOM simplification that saves board area and a dollar or more per unit at volume. The trade-off: FRAM density tops out lower than Flash in this family, so if the application needs more than 64 KB of code, you step up to a larger MSP430FR59xx variant. TI has not issued a last-time-buy notice or end-of-life notification for this base product number. For a production BOM, this means the part is still in volume manufacture and available through franchised distribution. No need to qualify a second source today, though the MSP430FR59xx family offers pin-compatible density variants if the firmware outgrows 64 KB. ## Package and thermal: 40-VQFN with exposed pad The MSP430FR5959IRHAT is supplied in a 40-VFQFN exposed-pad package, supplier device package 40-VQFN measuring 6x6 mm. The QFN footprint is compact — useful for space-constrained designs — but requires a solder stencil with appropriate aperture for the center pad to avoid voids. The part is surface-mount.","metaTitle":"MSP430FR5959IRHAT 16-bit MCU, 64KB FRAM, 16 MHz, 40-VQFN","metaDescription":"Texas Instruments MSP430FR5959IRHAT 16-bit MCU with 64KB FRAM, 2KB SRAM, 16 MHz core, 33 I/O, 12-bit ADC, 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":"2K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"33","Core Processor":"MSP430 CPUXV2","Package / Case":"40-VFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 16x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR5959","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"40-VQFN (6x6)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.5600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8b4ff231ab172f4b122f04a9e54765b3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MSP430FR5959IRHAT compatible with MSP430FR5959?","answer":"Yes — MSP430FR5959IRHAT is a specific ordering code variant of the base product MSP430FR5959.
