Overview
ST8024 Smartcard interface Features ■ Designed to be compatible with the NDS conditional access system ■ IC card interface ■ 3 or 5 V supply for the IC (VDD and GND) ■ Three specifically protected half-duplex bi- directional buffered I/O lines to card contacts C4, C7 and C8 ■ DC-DC converter for VCC generation separately powered from a 5 V ± 20% supply (VDDP and PGND) ■ 3 or 5 V ± 5 % regulated card supply voltage (VCC) with appropriate decoupling has the following capabilities: – ICC < 80 mA at VDDP = 4 to 6.
5 V – Handles current spikes of 40 nA up to 20 MHz – Controls rise and fall times – Filtered overload detection at approximately 120 mA ■ Thermal and short-circuit protection on all card contacts ■ Automatic activation and deactivation sequences; initiated by software or by hardware in the event of a short-circuit, card take-off, overheating, VDD or VDDP drop-out ■ Enhanced ESD protection on card side (> 6 kV) ■ 26 MHz integrated crystal oscillator ■ Clock generation for cards u...
