Buyers should verify date code and condition at quote time. ## 256 kB Flash and 16K x 8 RAM — memory headroom for protocol stacks The 256 kB Flash capacity is sized to hold a Bluetooth stack plus application code, leaving room for over-the-air update staging if the firmware architecture uses a swap or dual-bank scheme. The 16K x 8 RAM (16 KB) supports moderate data buffering for packet handling and sensor data logging. For designs that outgrow this memory envelope, a migration to a higher-density MSP430 or a Cortex-M0+ based Bluetooth MCU would be the typical next step. ## Peripheral set and I/O count for wireless sensor nodes The IrDA interface supports infrared data links for proximity or line-of-sight communication. The SCI (Smart Card Interface) is a less common feature that may be relevant for security token or payment-terminal designs.","metaTitle":"MSP430BT5190IZQWR Texas Instruments MCU, 256kB Flash","metaDescription":"Texas Instruments MSP430BT5190IZQWR 16-bit MCU with 256kB Flash, 16Kx8 RAM, 87 I/O, I²C/SPI/UART, Bluetooth application, -40°C to 85°C, 113-BGA.","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":"$6.4200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e14ffd0ecbaff13d4bedf6f2a6c3c608.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430BT5190IZQWR/alternatives.json"},"ai":{"faq":[{"question":"Is MSP430BT5190IZQWR obsolete?","answer":"Yes, the MSP430BT5190IZQWR is listed as obsolete by Texas Instruments.
