TDA8034T; TDA8034AT

Smart card interface

Rev. 3.1 — 13 December 2012

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

 Pay TV

 Electronic payment
