TDA8020HL/C1

Dual IC card interface

GENERAL DESCRIPTION

The TDA8020HL is a one-chip dual smart card interface. Controlled by the I2C-bus, it guarantees conformity to ISO 7816 or EMV2000 with very few external components.

FEATURES

• Two independent 6 contacts smart card interfaces

• Supply voltage to the cards: VCC= 5 V and ICCup to 60 mA or 3 V±5% and ICCup to 55 mA

• Integrated DC-to-DC converter doubler, tripler or follower for allowing power supply from 2.7 to 6.5 V

• Independent 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 EMV2000

• 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, card take-off or DC-to-DC malfunctioning

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

• Integrated voltage supervisor for power-on reset and drop-out detection.
