Confidential / Released

3.3.4.2,

3.3.4.3

Replaced resp. new sections on Deferred Shutdown at Extreme Temperature Condi-

tions and Monitoring the Board Temperature of AC75.

3.4 Minor text change.

3.3.1.3,

3.5.7, 3.7

To change from Charge-only mode to Normal mode the IGT line must be pulled low for

at least 1s and then released. High state of IGT lets AC75 enter Normal mode.

3.5 Replaced recommended polymer battery with new VARTA PoLiFlex® battery

3.5.7, 3.7 Described transition from Charge-only to Normal mode by switching off Airplane mode.

3.6 Added chapter on power saving.

3.12 AC75 does not support generic USB 2.0 High Speed hubs.

3.15.2.2 Added remarks on VMIC behaviour.

3.15.2.3 Replaced remark on VMIC behaviour.

3.15.4 Added Table 7: Configuration combinations for the PCM interface

5.1 New maximum values for voltage at analog pins with VMIC on/off.

5.2 Specified operating board temperature.

Table 22: Temperature specified for charging is battery temperature (not ambient)

5.5 Specified internal pull-down resistors 330k

Ω at TXD0, RXD0, TXD1, RXD1. Changed

all

min values from 2.0 to 2.15V.

Corrected overview table: USB_DP was listed in wrong row.

5.7 New chapter: Electrical Characteristics of the Voiceband Part

7 Modified description for Java “System.out” in sample application.

9 New datasheet for recommended VARTA PoLiFlex® Lithium polymer battery.
