IC card interface
Preliminary specification
TDA8004AT
FEATURES
3 or 5 V supply for the IC (GND and VDD)
Step-up converter for VCC generation (separately
powered with a 5 V ±10% supply, VDDP and PGND)
3 specific protected half duplex bidirectional buffered I/O
lines (C4, C7 and C8)
VCC regulation (5 or 3 V ±5% on 2 × 100 nF or
1 × 100 nF and 1 × 220 nF multilayer ceramic
capacitors with low ESR, ICC < 65 mA at
4.5 V < VDDP < 6.5 V, current spikes of 40 nAs up to
20 MHz, with controlled rise and fall times, filtered
overload detection approximately 90 mA)
Thermal and short-circuit protections 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 or supply
drop-out)
Enhanced ESD protection on card side (>6 kV)
26 MHz integrated crystal oscillator
Clock generation for the card up to 20 MHz (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 spikes killing during power-on
and power-off
One multiplexed status signal OFF.
APPLICATIONS
IC card readers for banking
Electronic payment
Identification
Pay TV.
GENERAL DESCRIPTION
The TDA8004AT is a complete low cost analog interface
for asynchronous 3 or 5 V smart cards. It can be placed
between the card and the microcontroller with very few
external components to perform all supply protection and
control functions.
