Product speciﬁcation

Dual smart card interface

TDA8020HL

FEATURES

• Two independent 6 contacts smart card interfaces

• Supply voltage to the cards; VCC =5 or 3V ±5%; ICC up

to 65 mA

• Integrated DC/DC converter (doubler, tripler or follower)

for allowing power supply from 2.5 to 6.5 V

• Independant supply voltage for interface signals (from

1.5 to 6.5 V)

• Control and status via the I2C-bus

• Four possible devices in parallel due to two I2C-bus

address pins

• Electrical specifications according to ISO 7816 or

EMV norms

• Automatic activation and deactivation sequences by

means of integrated sequencers

• Automatic clock count and reset toggling during warm or

cold reset

• Interrupt request output to the controller

• 6 kV ESD protection on cards contacts

• Automatic emergency deactivation in the event of

supply drop-out, overload, overheating or card take-off

• Current limitation on pins CLK, RST, I/O and VCC

• Integrated voltage supervisor for power-on reset and

drop-out detection

• Power-down mode with several wake-up events.

APPLICATIONS

• Set top boxes

• Banking terminals

• Internet terminals.

GENERAL DESCRIPTION

The TDA8020HL is a one-chip dual smart card interface.

Controlled by the I2C-bus, it guarantees conformity to

ISO 7816 or EMV norms with very few external

components.
