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 (V
DD
and GND)
■
Three specifically protected half-duplex bi-
directional buffered I/O lines to card contacts
C4, C7 and C8
■
DC/DC converter for V
CC
generation
separately powered from a 5 V ± 20% supply
(V
DDP
AND PGND)
■
3 or 5V ±5% regulated card supply voltage
(V
CC
) with appropriate decoupling has the
following capabilities:
– I
CC
< 80mA at V
DDP
= 4 to 6.5V
– Handles current spikes of 40nA up to
20MHz
– Controls rise and fall times
– Filtered overload detection at
approximately 120mA
■
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, V
DD
or V
DDP
drop-out
■
Enhanced ESD protection on card side (>6 kV)
■
26MHz integrated crystal oscillator
■
Clock generation for cards up to 20MHz
(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
Description
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.
Main applications are: smartcard readers for Set
Top Box, IC card readers for banking,
identification, Pay TV.
