1. Describe
The NCN8025AMNTXG is a compact and cost-effective single Smart Card Interface IC. It is dedicated to 1.8 V / 3.0 V / 5.0 V smart Card reader/writer application. Card VCC power is provided by a Built-in very low dropout and low noise LDO. The device is fully compliant with ISO 7816-3, EMV 4.3, UICC and related standards including NDS and other STB standards . it meets the specified requirements Conditional Access Set-Top Box (STB) or Conditional Access Modules (CAM and CAS). This smart card interface IC is available in a QFN-24 package (NCN8025A) typically provides all industry standard functions A set-top box smart card interface is required. It also provides a very The compact package outline, QFN-16 (NCN8025), meets the Cost-effectiveness and space-saving requirements for CAM requirements and SIM applications. For device implementation details, see the application Note AND8003/D, available upon request
