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.
