1 / 35 page This is information on a product in full production. May 2012 Doc ID 17709 Rev 5 1/35 1 ST8024L Smartcard interface Datasheet −production data Features ■ Designed to be compatible with the NDS conditional access system (except ST8024LTR) ■ ISO 7816, GSM11.11 and EMV 4.2 (payment systems) compatible ■ IC card interface ■ 3 V or 5 V supply for the ST8024L device (VDD) ■ Three specifically protected half-duplex bi-directional buffered I/O lines to card contacts C4, C7 and C8 ■ Step-up converter for VCC generation separately powered by a 5 V ± 20% supply (VDDP and PGND) ■ 1.8 V ± 6.5%, 3 V or 5 V ± 5% regulated card supply voltage (VCC) with appropriate decoupling has the following capabilities: –ICC < 80 mA at VDDP = 4.75 to 6.5 V – Handles current spikes of 40 nA up to 20 MHz – Controls rise and fall times – Filtered overload detection at ~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 dropout ■ Enhanced ESD protection on card side (>6 kV) ■ 26 MHz integrated crystal oscillator ■ Built-in debounce on card presence contacts ■ One multiplexed status signal OFF ■ Non-inverted control of RST via pin RSTIN ■ Clock generation for cards up to 20 MHz (divided by 1, 2, 4 or 8 through CLKDIV1 and CLKDIV2 signals) with synchronous frequency changes ■ Supply supervisor for spike-killing during power-on and power-off and power-on reset (threshold fixed internally or externally by a resistor divider) Applications ■ Smartcard readers for set-top boxes ■ IC card readers for banking ■ Identification, pay TV SO-28 TSSOP-28 TSSOP-20 Table 1.
