Smart Card Interface IC 28-Pin SOIC W T/R

The NCN8024R is a single smart card interface IC. It is dedicated for 3.0V/5.0V smart card reader/writer applications. The card VCC supply is provided by a very low drop-out and low noise regulator (LDO). The device is fully compatible with the ISO7816-3 and EMV standards as well as with standards specifying conditional access in Set-Top-Box (STB) including NDS. The smart card interface IC is available in an SOIC-28 package providing the industry-standard features required by STB smart card interfaces.

• Fully Compatible with ISO7816-3, EMV and Related STB standards including NDS
• Three bidirectional buffered I/O level shifters (C4, C7 and C8 card pins)
• 3.0 V or 5.0 V ±5% Regulated Card Power Supply such as ICC = 70 mA with 3.0 V = VDDP = 5.5V at 3.0 V (Class B) and 4.85 V = VDDP = 5.5V at 5.0 V (Class A)
• Independent Power Supply on Controller Interface (2.7 V = VDD = 5.5 V)
• Handles 5.0 V and 3.0 V Smart Cards (Class A and B)
• Support up to 27 MHz Clock with Internal Division Ratio 1/1, 1/2, 1/4 and 1/8 through CLKDIV1 and CLKDIV2 Pins
• ESD Protection up to ± 8 kV HBM
• Activation / Deactivation Sequences (ISO7816)
• 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 INTb for Card Presence and Faults
• External Under-Voltage Lockout Threshold Adjustment on VDD (PORADJ Pin)
