It's a fine-pitch BGA — not a part you'd hand-solder with a standard iron; you'll want a stencil, reflow oven, and preferably an X-ray for post-solder inspection. With 74 I/O lines available, you have enough pins to interface a parallel LCD or a bank of sensors alongside the USB connection. ## Memory and USB — the two specs that decide fit The 256 KB Flash and 18 KB RAM are the first gate for firmware size. A USB CDC or HID stack plus a modest application typically fits in 64–128 KB, so this part leaves headroom for field-upgradeable firmware or a more complex protocol stack. The USB peripheral supports device mode (not host mode natively — see FAQ), which covers the common use case of a peripheral like a data logger or a virtual COM port. If your design needs USB host capability (e.g., reading a USB flash drive), you'd need an external USB host controller or a different MCU with an OTG PHY. ## Lifecycle and compliance This is a standard RoHS-compliant part (no lead in the solder balls or package finish).","metaTitle":"Texas Instruments MSP430F5638IZCAR 16-bit MCU, 20MHz","metaDescription":"TI MSP430F5638IZCAR 16-bit MCU with 20MHz core, 256KB Flash, 18KB RAM, USB 2.0, industrial temp -40°C to 85°C, 113-NFBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","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":"Active","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-NFBGA (7x7)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.8406","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3ee2c0746af02feaac7c1d0954604055.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can MSP430F5638IZCAR be used in USB host mode?","answer":"No, the USB peripheral on this MCU supports device mode only (full-speed 12 Mbps). It does not have an on-chip USB host controller or OTG transceiver, so it cannot act as a USB host to connect keyboards, flash drives, or other USB devices directly. For host capability, you would need an external USB host controller chip or a different MCU with USB OTG support."},{"question":"Is MSP430F5638IZCAR RoHS compliant?","answer":"Yes, this is a RoHS-compliant component. Texas Instruments marks RoHS compliance on the product label and the datasheet confirms lead-free solder balls. No exemption declarations are needed for standard EU RoHS compliance."},{"question":"Does MSP430F5638IZCAR support USB 2.0?","answer":"Yes, the integrated USB module is compliant with USB 2.0 full-speed (12 Mbps) specification. It does not support high-speed (480 Mbps) or low-speed (1.5 Mbps) modes. For most human-interface devices and virtual COM port applications, full-speed is sufficient."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430F5638IZCAR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430F5638IZCAR when reusing this data.
