1. General description
2. Features and benefits
2.1 Protection of the contact smart card
2.2 Easy integration into your contact reader
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.
TDA8035HN
Smart card interface
Rev. 1.0 — 19 April 2011
Thermal and short-circuit protections on all card contacts
Vcc regulation:
Automatic activation and deactivation sequences initiated by software or by hardware
in the event of a short-circuit, card take-off, overheating, falling V
Enhanced card-side ElectroStatic Discharge (ESD) protection of (> 8 kV)
Supply supervisor for killing spikes during power on and off:
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
Non-inverted control of pin RST using pin RSTIN
Built-in debouncing on card presence contact
Multiplexed status signal using pin OFFN
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
