DESCRIPTION
The Teridian 73S8024C is a single smart card
interface IC. It provides full electrical compliance
with ISO-7816-3, EMV 4.0 and NDS specifications
1.
Interfacing with the system controller is done through
the control bus, composed of digital inputs to control
the interface, and one interrupt output to inform the
system controller of the card presence and faults.
Data exchange with the card is managed from the
system controller using the I/O line (and eventually
the auxiliary I/O lines). Hardware support for
auxiliary I/O lines, C4 / C8 contacts, is provided.
The card clock signal can be generated by an on-chip
oscillator using an external crystal or by connection to
a clock signal coming from the system controller.
The Teridian 73S8024C device incorporates an
ISO-7816-3 activation/deactivation sequencer that
controls the card signals. Level shifters drive the
card signals with the selected card voltage (3 V or
5 V), coming from an internal DC-DC converter.
With its high-efficiency DC-DC converter, the
Teridian 73S8024C is a cost-effective solution for
any smart card reader application to be powered
from a single 2.7 V to 3.6 V power supply.
Emergency card deactivation is initiated upon card
extraction or upon any fault generated by the
protection circuitry. The fault can be a VDD (digital
power supply) or a VCC (card power supply) failure,
a card over-current, or
The only smart card interface IC firmware
compatible with the TDA8004 operating with a
single 2.7 V to 3.6 V power supply (allows
removal of 5 V from the system)
an over-heating fault.
ADVANTAGES
The inductor-based DC-DC converter provides
higher current and efficiency than the usual
charge-pump capacitor-based converters
Ideal for battery-powered applications
Suitable for high current cards and SAMs:
(100 mA max)
Power down mode: 2
