Smart card interface

Rev. 2.0 — 12 November 2010

Product data sheet

1. General description

The TDA8034T/TDA8034AT is a cost-effective analog interface for asynchronous and

synchronous smart cards operating at 5 V or 3 V. Using few external components, the

TDA8034T/TDA8034AT provides all supply, protection and control functions between a

smart card and the microcontroller.

2. Features and benefits

Integrated circuit smart card interface in an SO16 package

5 V or 3 V smart card supply

One protected half-duplex bidirectional buffered I/O line (C7)

V_CCregulation:

5 V ± 5 % or 3 V ± 5 % using two low ESR multilayer ceramic capacitors: one of

220 nF and one of 470 nF

current spikes of 40 nA/s (V_CC= 5 V and 3 V) or 15 nA/s (V_CC=1.8 V) up to

20 MHz, with controlled rise and fall times and filtered overload detection of

approximately 120 mA

Thermal and short-circuit protection for all card contacts

Automatic activation and deactivation sequences triggered by a short-circuit, card

take-off, overheating, falling V_DD, V_DD(INTF)or V_DDP

Enhanced card-side ElectroStatic Discharge (ESD) protection of > 6 kV

External clock input up to 26 MHz connected to pin XTAL1

Card clock generation up to 20 MHz using pin CLKDIV1 with synchronous frequency

changes of:

¹∨₂f_xtalor ¹∨₄f_xtalon TDA8034T

f_xtalor ¹∨₂f_xtalon TDA8034AT

Non-inverted control of pin RST using pin RSTIN

Compatible with ISO 7816, NDS and EMV 4.2 payment systems

Supply supervisor for killing spikes during power on and off:

using a fixed threshold

using an external resistor bridge with threshold adjustment

Built-in debouncing on card presence contacts (typically 4.5 ms)

Multiplexed status signal using pin OFFN

3. Applications
