TDA8035HN

Smart card interface

Rev. 1.0 — 19 April 2011

Product data sheet

1. General description

The TDA8035 is the cost efficient successor of the well established integrated contact

smart card reader IC TDA8024. It offers a high level of security for the card performing

current limitation, short circuit detection, ESD protection as well as supply supervision.

Operating in 3 V supply domain, the current consumption during the standby mode of the

contact reader is very low and is therefore the ideal component for a power efficient

contact reader.

2. Features and benefits

2.1 Protection of the contact smart card

Thermal and short-circuit protections on all card contacts

Vcc regulation:

5 V, 3 V, 1.8 V ± 5 % on 2 × 220 nF multilayer ceramic capacitors with low ESR

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, filtered overload detection

approximately 120 mA

Automatic activation and deactivation sequences initiated by software or by hardware

in the event of a short-circuit, card take-off, overheating, falling V_REGV_DD(INTF),V_DDP

Enhanced card-side ElectroStatic Discharge (ESD) protection of (> 8 kV)

Supply supervisor for killing spikes during power on and off:

threshold internally fixed

externally by a resistor bridge

2.2 Easy integration into your contact reader

SW compatible to TDA8024 and TDA8034

5 V, 3 V, 1.8 V smart card supply

DC/DC converter for Vcc generation separately powered from 2.7 V to 5.5 V supply

(VDDP and GNDP)

Very low power consumption in Deep Shutdown mode

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

External clock input up to 26 MHz

Card clock generation up to 20 MHz using pins CLKDIV1 and CLKDIV2 with

synchronous frequency changes of f_XTAL,f_{XTAL/2, XTAL/4}or f_XTAL/8

Non-inverted control of pin RST using pin RSTIN

Built-in debouncing on card presence contact

Multiplexed status signal using pin OFFN
