DescriptionIt is assumed that the reader of this data sheet is familiar with ISO 7816.
TheTDA8006iscontrolledeitherthroughastandardserial interface or a parallel bus, it takes care of all ISO 7816,
EMV and GSM11.11 requirements. It gives the card and the set a very high level of security due to its special hardware against ESD, short circuit, power failure, etc.
Its integrated step-up converter allows operation within a supply voltage range of 4.2 to 6 V.
A specialversionoftheTDA8006isavailablewhichhasits internal connections to the controller accessible through external pins. This allows easy development and evaluationwhenusedwitha80CL580microcontrollerora development tool. An emulation board is available.
A software library has been developed, taking care of all actions required for T = 0, T = 1 and synchronous protocols. This library may be either linked with the application software before masking, or masked in the internal ROM (see "Application Note AN98106").
