DESCRIPTION

The STLC2410B 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 an external memory accessed through the external memory interface.
