TDA8035
High integrated and low power smart card interface
Rev. 3.1 — 30 June 2016
Product data sheet
1. General description
The TDA8035 is the cost efficient successor of the established integrated contact smart
card reader IC TDA8024. It offers a high level of security for the card by performing
current limitation, short-circuit detection, ESD protection as well as supply supervision.
The current consumption during the standby mode of the contact reader is very low as it
operates in the 3 V supply domain. The TDA8035 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 protection 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 is
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 VREG VDD(INTF),VDDP
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-to-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 fXTAL, fXTAL/2, fXTAL/4 or fXTAL/8
Non-inverted control of pin RST using pin RSTIN
Built-in debouncing on card presence contact
Multiplexed status signal using pin OFFN
