Product specification

TDA8004T

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 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)

• 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 TDA8004T is a complete low cost analog interface for

asynchronous smart cards. It can be placed betw the card

and the microcontroller with very few external components

to perform all supply protection and control functions.
