The TDA8005A is a low-cost card interface for portable smart card readers. Controlled through a standard serial interface, it takes care of all ISO 7816 and GSM11.11 requirements for both 5 and 3 V cards. It gives the card and the set a very high level of security, due to its special hardware against ESD, short-circuiting, power failure, etc. Its integrated step-up converter allows operation within a
supply voltage range of 2.5 to 6 V.
