DESCRIPTION
The TERIDIAN 73S8010C is a single smart card interface
IC. It provides full electrical compliance with ISO-7816-3,
EMV 4.0 specifications.
Interfacing with the host is done through the two-wire I
2C
bus. Data exchange with the card is managed from the
system controller using the I/O line (and eventually the
auxiliary I/O lines).
An on-chip oscillator using an external crystal, or
connection to a clock signal coming from the system
controller can generate the card clock signal.
The TERIDIAN 73S8010C IC incorporates an ISO-7816-3
activation/deactivation sequencer that controls the card
signals. Level-shifters drive the card signals with the
selected card voltage (3V or 5V), coming from an internal
DC-DC converter.
With its high-efficiency DC-DC converter, the TERIDIAN
73S8010C is a cost-effective solution for any smart card
reader application to be powered up from a single 2.7V to
3.6V power supply.
Hardware support for auxiliary I/O lines, C4 / C8 contacts,
is provided.
Emergency card deactivation is initiated upon card
extraction or upon any fault generated by the protection
circuitry. The fault can be a card over-current, a VDD
(digital power supply), a VCC (card power supply) or an
over-heating fault.
