DESCRIPTION

The STLC2411 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.

FEATURES

■ Pin to pin compatible with the previous version STLC2410B

■ Ericsson Technology Licensing Baseband Core (EBC)
