Philips Semiconductors
Dual IC card interface
Product specification
TDA8020HL
FEATURES
• Two independent 6 contacts smart card interfaces
• Supply voltage to the cards: VCC = 5 V and ICC up to
60 mA or 3 V ±5% and ICC up 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.
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 EMV2000 with very few external components.
