The FRAM is organized as 64K x 8 bits, and the part also carries 2K x 8 of conventional RAM for stack and scratchpad use. This makes the MSP430FR5949IRHAR a strong fit for applications that need frequent data logging, field-upgradeable firmware, or low-energy writes without the erase-cycle overhead of Flash. ## Peripheral set for sensor-heavy designs A 14-channel, 12-bit ADC handles multi-sensor acquisition without external converters — think temperature, pressure, and current sensing on one die. The 33 general-purpose I/O lines support parallel interfaces and keypad scanning. ## Package and layout notes The MSP430FR5949IRHAR comes in a 40-pin VFQFN with an exposed thermal pad (6x6 mm body). The package is surface-mount only, so hand-assembly requires a hot-air station or reflow oven. ## Lifecycle and sourcing This is a standard-production TI MSP430 part, so it is available through the usual distribution channels. For BOM planning, the active status means no last-time-buy urgency, but the 40-VQFN package is moisture-sensitive — store the reels in a dry cabinet or bake before reflow if the moisture-barrier bag has been open past the floor-life window.","metaTitle":"TI MSP430FR5949IRHAR 16-bit MCU, 64KB FRAM, 16 MHz, 40-VQFN","metaDescription":"Texas Instruments MSP430FR5949IRHAR 16-bit MCU with 64KB FRAM, 16 MHz CPUXV2 core, 14-channel 12-bit ADC, 33 I/O, -40 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 14x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR5949","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":"$6.3000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/daf738d4497f8f51eb23b38fa776a403.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the FRAM size and how is it organized in MSP430FR5949IRHAR?","answer":"The FRAM program memory is 64 KB, organized as 64K x 8 bits.
