Product Description

Description
The ST8024 is a complete low cost analog interface for asynchronous 3 V and 5 V smart cards. It can be placed between the card and the microcontroller with few external components to perform all supply protection and control functions. ST8024 is a direct replacement of ST8004.
Features
■ Designed to be compatible with the NDS conditional access system
■ IC card interface
■ 3 or 5 V supply for the IC (VDDand GND)
■ Three specifically protected half-duplex bidirectional 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 (VDDPand 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, VDDor VDDPdrop-out ■ Enhanced ESD protection on card side (>6 kV)
■ 26 MHz integrated crystal oscillator
■ Clock generation for cards up to 20 MHz (divided by 1, 2, 4 or 8 through CLKDIV1 and CLKDIV2 signals) with synchronous frequency changes
■ Non-inverted control of RST via pin RSTIN
■ ISO 7816, GSM11.11 and EMV (payment systems) compatibility
■ Supply supervisor for spike-killing during power-on and power-off and power-on reset (threshold fixed internally or externally by a resistor bridge)
■ Built-in debounce on card presence contacts
■ One multiplexed status signal off
