The phone supports full speed (12 Mb/s) in device mode.
Charger interface
The charger interface is a 2 mm Dynamo charger plug. Older chargers with a 3.5 mm plug are supported via
the charger adapter cable CA-44.
Charging is controlled by GAZOO (N2200). Additional external components are needed for EMC purposes,
reverse polarity and transient protection of the input to the baseband module.

Bluetooth
Bluetooth provides a fully digital link for communication between a master unit (the phone) and one or more
slave units (e.g. a wireless headset). Data and control interface for a low power RF module is provided by the
module.
The Bluetooth is physically integrated with the FM radio into one single module. From a functional point of
view they, however, have nothing in common.
Figure 37 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.
FM radio
The FM radio is physically integrated with the Bluetooth into one single module. From a functional point of
view they, however, have nothing in common.
