ST8024  
Smartcard interface  
General features  
Designed to be compatible with the NDS  
conditional access system  
IC card interface  
3 or 5V 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  
TSSOP28  
SO-28  
DC/DC converter for VCC generation  
separately powered from a 5 V 20% supply  
(VDDP AND PGND)  
Non-inverted control of RST via pin RSTIN  
ISO 7816, GSM11.11 and EMV (payment  
3 or 5V 5% regulated card supply voltage  
(VCC) with appropriate decoupling has the  
following capabilities:  
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)  
– ICC < 80mA at VDDP = 4 to 6.5V  
– Handles current spikes of 40nA up to  
20MHz  
Built-in debounce on card presence contacts  
One multiplexed status signal off  
– Controls rise and fall times  
– Filtered overload detection at  
approximately 120mA  
Description  
Thermal and short-circuit protection on all card  
contacts  
The ST8024 is a complete low cost analog  
interface for asynchronous 3V and 5V 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.  
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)  
26MHz integrated crystal oscillator  
Main applications are: smartcard readers for Set  
Top Box, IC card readers for banking,  
identification, Pay TV.  
Clock generation for cards up to 20MHz  
(divided by 1, 2, 4 or 8 through CLKDIV1 and  
CLKDIV2 signals) with synchronous frequency  
changes
