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
SO-28
TSSOP-20
TSSOP-28
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
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)
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
Applications
Smartcard readers for set-top boxes
IC card readers for banking
Identification, pay TV
