It packs 256KB of Flash and 18KB of RAM — enough for a USB stack plus a modest application layer without external memory. The 113-VFBGA package (BGA Microstar Junior, 7x7 mm) means the board layout must handle a 0.50 mm or finer ball pitch — this is not a hand-solderable part. The 74 I/O lines give enough headroom for a parallel LCD, external memory bus, and sensor array without multiplexing. ## Obsolete — what that means for a BOM line Texas Instruments has marked the MSP430F5638IZQWT as Obsolete. For existing designs already in production, the remaining supply moves through independent distribution — quantities are lot-specific and confirmed at RFQ. If you are sourcing this for a repair or a last-time-buy fill, the 113-BGA Microstar Junior footprint is the constraint. A pin-compatible drop-in from the same MSP430F5xx family would need to share the same ball map — something to verify against the TI package drawing before committing a replacement. ## Peripheral set and connectivity — USB, ADC, and the analog chain On-chip USB 2.0 (full-speed) with the PHY integrated — no external USB transceiver needed. The connectivity block also includes I²C, SPI, UART/USART, LINbus, and IrDA, which covers most industrial sensor bus and debug interfaces. The data converter section provides 16-channel 12-bit ADC and 2-channel 12-bit DAC. For a mixed-signal application like a portable data logger or a sensor hub, the ADC can sample all 16 channels without an external mux, and the DAC outputs can drive analog set-points or alarm thresholds directly. Built-in brown-out detect, POR, DMA, and PWM peripherals reduce external supervisor and timer IC count. ## Temperature grade and supply range This covers most factory-floor and outdoor enclosure environments without active cooling.","metaTitle":"TI MSP430F5638IZQWT 16-bit MCU, 256KB Flash, 20MHz, 113-BGA","metaDescription":"Texas Instruments MSP430F5638IZQWT 16-bit MCU, 256KB Flash, 18KB RAM, 20MHz, USB, 74 I/O, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"20MHz","Series":"MSP430F5xx","Package":"Tape & Reel (TR)","RAM Size":"18K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SCI, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"74","Core Processor":"MSP430 CPUXV2","Package / Case":"113-VFBGA","Product Status":"Obsolete","Data Converters":"A/D 16x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F5638","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"113-BGA Microstar Junior (7x7)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d0f0be01b1fb6b2469fb4f76de7d1e17.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F5638IZQWT/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy MSP430F5638IZQWT and check availability?","answer":"We source the MSP430F5638IZQWT through independent distribution channels.
