Product details

MSP430BT5190IPZ — 16-bit MCU with Bluetooth application profile

It carries 256 KB of program Flash and 16K x 8 of RAM, with 87 general-purpose I/O lines brought out to a 100-pin LQFP package (14x14 mm body). 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.

Frequently asked questions

Does the MSP430BT5190IPZ have built-in Bluetooth?

No, the MSP430BT5190IPZ does not contain an integrated Bluetooth radio. The 'Applications: Bluetooth' field indicates the MCU is provisioned as a host controller for an external Bluetooth chipset — typically a TI CC2564 or similar — communicating over UART or SPI.

What is the difference between MSP430BT5190IPZ and MSP430F5438?

The MSP430BT5190IPZ is a Bluetooth-application-specific variant with 256 KB Flash and 16K x 8 RAM in a 100-LQFP. The BT5190 is the part to pick when the design targets a Bluetooth host controller role; the F5438 is for general-purpose applications where the Bluetooth tag is not needed.
