Product Description

Overview
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.

## Features
* 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)
* VCC regulation:
* 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 (VCC = 5 V and 3 V) or 15 nA/s (VCC =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 VDD, VDD(INTF) or VDDP
* 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:
* 1/2 fxtal or 1/4 fxtal on TDA8034T
* fxtal or 1/2 fxtal on 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
## Target Applications
* Pay TV
* Electronic payment
* Identification
* Bank card readers
