  Single Interface Chip Controls Two Smart Cards – Design Note 289
  Steven Martin
  Introduction
  There are considerable challenges to smart card interfacing, including various voltage levels (both input and
  output) and stringent fault handling requirements. To
  produce a robust card reading system, designers must
  comply with extensive and often difficult software as
  well as hardware standards. Furthermore, there are
  other complications like in-circuit ESD and pin-to-pin
  shorts to contend with.
  The LTC В®1955 dual smart card interface provides all
  of the required power management, control, ESD and
  fault detection circuitry for two smart cards. Employing
  a voltage doubling charge pump and two low dropout
  linear regulators, this device generates two independent levels of either 5V, 3V or 1.8V from a 2.7V to 5.5V input. Both channels have the required pins to support
  the EMV (Europay, MasterCard, Visa) and the ISO7816
  smart card standards. One channel has extra control
  pins (smart card contact pad locations C4 and C8)
  to support existing memory cards. The entire chip is
  controlled by a microcontroller-friendly serial interface.
  Features
  The LTC1955 includes considerable security and functionality, yet remains easy to use. Two independent
  circuits detect the presence or absence of a smart …
