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
