The part is specifically listed for Bluetooth applications, meaning it integrates the peripheral set and memory footprint suited for Bluetooth stack hosting — typically a TI CC256x companion device over UART or SPI. ## Serial interface set and I/O budget With 87 I/Os in a 100-pin package, the designer gets a dense I/O count for parallel buses, keypad matrices, or multiple chip selects. The remaining 13 pins are consumed by supply, ground, oscillator, and JTAG/SBW debug. ## Package and footprint — 100-LQFP 14x14 The exposed pad (if present on this variant) should be stitched to ground with thermal vias — the datasheet's recommended land pattern and via array are the reference, not a generic QFP pattern. Surface-mount only, tray shipping.","metaTitle":"Texas Instruments MSP430BT5190IPZ 16-bit MCU, 256KB Flash","metaDescription":"MSP430BT5190IPZ 16-bit MCU with 256KB Flash, 16Kx8 RAM, 87 I/O, I²C/SPI/UART, industrial temp -40°C~85°C.
