GENERAL DESCRIPTION
TDA8002C
The TDA8002C is a complete low-power analog interface
for asynchronous and synchronous cards. It can be placed
between the card and the microcontroller. It performs all
supply, protection and control functions. It is directly
compatible with ISO 7816, GSM11.11 and EMV
specifications.
