Figure 52 Bluetooth interface

The Bluetooth has a separate built in antenna and is powered by VBAT and the regulated voltage VIO. For

audio applications the Bluetooth has a PCM data bus. In addition a UART (universal asynchronous receiver/

transmitter) is used for data communication and controls.

WLAN

A Wireless Local Area Network (WLAN) is a flexible data communication system in which a mobile user can

connect to a local area network through a wireless connection. The standard, which specifies the technologies

for WLAN, is called IEEE 802.11. The device supports both IEEE 802.11b and 802.11g standards, so the

supported data rates are from 1 Mbps to 54 Mbps in 2.4 GHz ISM band.
