DESCRIPTION
APPLICATIONS
•
GSM mobile phones
TDA8003TS
•
SAM interfaces in banking terminals
•
Portable card readers, etc.
GENERAL DESCRIPTION
The TDA8003TS is a low cost one chip SIM interface, in
accordance with GSM11.11, GSM11.12 and EMV96
(Europay, Mastercard, Visa) with card current limitation.
Controlled by I
2
C-bus, it is optimized in terms of board
space, external components count and connection count
(see Chapter “Application information”).
The integrated DC-to-DC converter ensures full
cross-compatibility between 3 or 5 V cards and 3 or 5 V
environments. The very low-power consumption in
Power-down mode and Off mode saves battery power.

. The switch is normally closed when the card is not present. If the switch connection is open-circuit or pin 16
is not connected, then the interface will always detect a present card (see Fig.7).
