DESCRIPTION

The STLC2416 from STMicroelectronics is a Bluetooth? baseband controller with integrated 4 Mbit flash memory. Together with a Bluetooth? Radio this product offers a compact and complete solution for short-range wireless connectivity. It incorporates all the lower layer functions of the Bluetooth? protocol.

The microcontroller allows the support of all data packets of Bluetooth? in addition to voice. The embedded controller can be used to run the Bluetooth? protocol and application layers if required. The software is located in the integrated flash memory.
