TDA8034HN

Low power smart card interface

Rev. 3.4 — 29 June 2016

Product data sheet

1. 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.

2. Features and benefits

 Integrated circuit smart card interface in an HVQFN24 package

 5 V, 3 V or 1.8 V smart card supply

 Very low power consumption in Deep Shutdown mode

 Three protected half-duplex bidirectional buffered I/O lines (C4, C7 and C8)

 V_CCregulation:

 5 V, 3 V or 1.8 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 > 8 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 f_xtal, ¹⁄₂f_xtal,¹⁄₄f_xtalor ¹⁄₈f_xtal

 Non-inverted control of pin RST using pin RSTIN

 Compatible with ISO 7816, NDS and EMVCo4.3 ¹payment 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
