TDA8003TS; IC-bus SIM card interface
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 IC-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.
