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.

FEATURES
• Two independent 6 contacts smart card interfaces
• Supply voltage to the cards; VCC = 5 or 3 V ±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.
