ON Semiconductor NCN8025A is a compact and cost effective single smart card interface. It is dedicated for 1.8V / 3.0V / 5.0V smart card reader/writer applications. The card Vcc supply is provided by a built in very low dropout and low noise LDO. The device is fully compatible with the ISO 7816-3, EMV 4.2, UICC and related standards including NDS and other STB standards (Nagravision, Irdeto...). It satisfies the requirements specifying conditional access into Set Top Boxes (STB) or Conditional Access Modules (CAM and CAS). This smart card interface IC is available in a QFN-24 package providing all of the industry standard features usually required for STB smart card interface.
