The NCN8026A is a compact and cost-effective single SIM and smart card interface IC. It can be used with 1.8 V, 3 V and 5 V IC cards. The card VCC supply is provided by a built-in very low drop-out and low noise Regulator. The NCN8026A offers enhanced performances with low VCC output ripple under load-transient conditions, very low shutdown current and 1.8 V-to-5 V logic compatibility. This device is fully compatible with the ISO 7816-3, EMV 4.2, UICC and related standards including STB standards (Nagravision, Irdeto, Conax...). It satisfies the requirements specifying conditional access into Set-Top-Boxes (STB) or Conditional Access Modules (CAM). This smart card interface IC is available in a QFN-24 package providing all the industry-standard features usually required for STB smart card interface.
