The 64 KB program space is ample for moderate control loops and communications stacks; the 2 KB RAM handles stack and temporary variables. For designs that previously needed external EEPROM, this part absorbs that function on-chip. ## Package and mounting — 38-pin TSSOP Housed in a 38-TSSOP (0.240\", 6.10 mm width), this is a surface-mount part with 0.65 mm pitch. The narrow body saves board area but calls for a decent soldering profile — rework with a hot-air station is doable, but the fine pitch means double-checking alignment before reflow. ## Lifecycle and supply posture No stock or lead-time numbers here, but the part is in the active channel.","metaTitle":"TI MSP430FR5949IDAR 16-bit MCU, 64KB FRAM, 38-TSSOP","metaDescription":"Texas Instruments MSP430FR5949IDAR 16-bit MCU with 64KB FRAM, 2KB RAM, 16MHz CPU, 12x12b ADC, I²C/SPI/UART, -40°C to 85°C, 38-TSSOP.","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":"31","Core Processor":"MSP430 CPUXV2","Package / Case":"38-TSSOP (0.240\\\", 6.10mm Width)","Product Status":"Active","Data Converters":"A/D 12x12b","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":"38-TSSOP","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":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430FR5949IDAR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430FR5949IDAR when reusing this data.
