The 16K x 8 RAM is the working memory for packet buffers and stack variables — a full BT stack with GATT and SPP profiles typically leaves 4–6 KB for application data, so the buffer budget needs sizing before committing the BOM line. ## Active production — no LTB or NRND flags Texas Instruments lists the MSP430BT5190IZCAT as Active with no last-time-buy or not-recommended-for-new-designs notice. ROHS3 compliant with no exemptions — fits EU and global RoHS requirements without a waiver. ## Peripheral set — sensor and host comms The interface set includes I²C, IrDA, SCI, SPI, and UART/USART — covers the common sensor buses (I²C, SPI) and host communication (UART for BT HCI transport, IrDA for legacy optical links). The SCI (Serial Communications Interface) is TI's name for the UART module with hardware flow control, useful for the Bluetooth HCI UART transport layer.","metaTitle":"TI MSP430BT5190IZCAT Bluetooth MCU, 256kB Flash, 113-BGA","metaDescription":"Texas Instruments MSP430BT5190IZCAT Bluetooth microcontroller, 256kB Flash, 16Kx8 RAM, 1.8-3.6V, -40 to 85°C, 113-NFBGA.
