Industrial temperature grade (-40 to 85 °C) covers outdoor gateways, automotive cabin modules, and factory-floor sensor nodes where the ambient stays below the 85 °C ceiling. ## EOL status — what it means for procurement Texas Instruments has marked the MSP430BT5190IZQWT as obsolete. For existing designs, the remaining supply flows through independent surplus channels. Availability is lot-specific and confirmed at RFQ — date-code traceability and authenticity verification are part of the sourcing process.","metaTitle":"TI MSP430BT5190IZQWT MCU, 256kB Flash, 113-BGA, Obsolete","metaDescription":"Texas Instruments MSP430BT5190IZQWT Bluetooth MCU, 256kB Flash, 16KB RAM, 113-BGA Microstar Junior.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Series":"MSP430","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"16K x 8","Interface":"I²C, IrDA, SCI, SPI, UART/USART","Applications":"Bluetooth","Mounting Type":"Surface Mount","Number of I/O":"87","Core Processor":"-","Package / Case":"113-VFBGA","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Voltage - Supply":"1.8V ~ 3.6V","Controller Series":"MSP430","Base Product Number":"430BT5190","Program Memory Type":"FLASH (256kB)","Operating Temperature":"-40°C~85°C","Supplier Device Package":"113-BGA Microstar Junior (7x7)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.7100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e14ffd0ecbaff13d4bedf6f2a6c3c608.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430BT5190IZQWT/alternatives.json"},"ai":{"faq":[{"question":"What interfaces does the MSP430BT5190IZQWT support?","answer":"The MCU integrates I²C, IrDA, SCI, SPI, and UART/USART serial interfaces, covering the common protocols for sensor, display, and wireless module communication."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430BT5190IZQWT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430BT5190IZQWT when reusing this data.
