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

■ DC/DC converter for VCC generation

separately powered from a 5 V ± 20% supply

(VDDP AND PGND)

■ 3 or 5V ±5% regulated card supply voltage

(VCC) with appropriate decoupling has the

following capabilities:

–ICC < 80mA at VDDP = 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, VDD or VDDP 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.
