APPLICATIONS
GENERAL DESCRIPTION
The TDA8002 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.
