General description
The TDA8034HN is a cost-effective analog interface for asynchronous and synchronous
smart cards operating at 5 V, 3 V or 1.8 V. Using few external components, the
TDA8034HN provides all supply, protection and control functions between a smart card
and the microcontroller.

Features and benefits
Integrated circuit smart card interface in an HVQFN24 package
5V, 3V or 1.8V smart card supply
Very low power consumption in Deep Shutdown mode
Three protected half-duplex bidirectional buffered I/O lines (C4, C7 and C8)
VCC regulation:
5V, 3V or 1.8V
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 pins CLKDIV1 and CLKDIV2 with
synchronous frequency changes of fxtal, 12 fxtal, 14 fxtal or 18 fxtal
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 8 ms)
Multiplexed status signal using pin OFFN
