It packs 256 KB of program FLASH and 16K x 8 of RAM in a 100-pin LQFP (14x14 mm) package — enough memory to run a Bluetooth stack and application code, though the 16 KB RAM means you will budget the heap carefully if you are doing over-the-air updates or holding large buffers.
The MSP430BT5190IPZR is available to order through independent distribution.
No official successor is listed for the MSP430BT5190IPZR. The part remains active in TI's portfolio, so no replacement is needed for current production. For a pin-compatible alternative within the MSP430 family, review the MSP430BT5190IZQWR variant — it shares the same base product number and Bluetooth application tag, though package and tape details differ.
