1.1 Applications Features Typical applications in which the STLC2410B can be used are:

Portable computers, PDA Modems Handheld data transfer devices Cameras Computer peripherals Other type of devices that require the wireless communication provided by Bluetooth® Cable replacement

2 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.

This is preliminary information, details are subject to change without notice.

3.1 Absolute Maximum Ratings Operation of the device beyond these conditions is not guaranteed. Sustained exposure to these limits will adversely affect device reliability Table 1. Absolute Maximum Ratings
