NCN8025A Smart Card Interface

ON Semiconductor's NCN8025A is a compact and cost effective single smart card interface IC. It is dedicated for 1.8 V / 3.0 V / 5.0 V 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 (NCN8025A) providing all of the industry standard features usually required for STB smart card interface. It is also offered in a very compact package profile, QFN-16 (NCN8025), satisfying the requirements of cost efficiency and space saving requested by CAM and SIM applications.

Features

  • Fully compatible with ISO-7816-3, EMV4.2, UICC and related standards including NDS and other STB standards (Nagravision, Irdeto)
  • 3 bidirectional buffered I/O level shifters (C4, C7 and C8)(QFN-24)- 1 bidirectional I/O level shifter (C7)for the QFN-16 compact version
  • 1.8 V, 3.0 V or 5.0 V +/- 5% regulated card power supply such as ICC ≤ 70 mA
  • Regulator power supply: VDDP = 2.7 V to 5.5 V (at 1.8 V), 3.0 V to 5.5 V (at 3.0V) & 4.85 V to 5.5 V (at 5.0 V)
  • Independent power supply on controller interface: VDD = 2.7 V to 5.5 V
  • Handle class A, B & C smart cards
  • Short circuit protection on all card pins
  • Support up to 27 MHz input clock with internal division ratio 1/1, 1/2, 1/4, 1/8 through CLKDIV1 and CLKDIV2
  • ESD protection on card pins up to +8 kV (Human Body Model)
  • Activation/Deactivation sequence (ISO7816 sequencer)
  • Fault protection mechanisms enabling automatic device deactivation in case of overload, overheating, card take-off or power supply drop-out (OCP, OTP, UVP)
  • Interrupt signal /INT for card presence and faults
  • External undervoltage lockout threshold adjustment on VDD (PORADJ pin) (Except QFN-16)
  • Available in 2 package formats: QFN-24 (NCN8025A) and QFN-16 (NCN8025)

Applications

  • Pay TV, Set-Top-Box, decoder with conditional access and pay-per-view
  • Conditional Access Module (CAM)
  • Conditional Access System (CAS)
  • SIM card interface applications (UICC / USIM)
  • Point Of Sales (POS) and transaction terminals
  • Electronic payment and identification
