Low Cost Smart Card Interface

DESCRIPTION
The TERIDIAN 73S8010R is a single smart card interface
IC. The TERIDIAN 73S8010R has been designed to
provide full electrical compliance with ISO-7816-3 and
EMV 4.0 (EMV2000) specifications.
Interfacing with the host is done through the two-wire I
2C
bus, and one interrupt output to inform the system
controller of the card presence and faults.
The card clock signal can be generated by an on-chip
oscillator using an external crystal, or by connection to a
clock signal.
The TERIDIAN 73S8010R 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
Low Drop-Out (LDO) voltage regulator. This LDO regulator
is powered by a dedicated power supply input VPC. Digital
circuitry is separately powered by a digital power supply
VDD.
With its embedded LDO regulator, the TERIDIAN
73S8010R is a cost-effective solution for any application
where a 5V (typically -5% +10%) power supply is
available.
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 VPC (regulator power supply), a
VCC (card power supply) or an over-heating fault.
The card over-current circuitry is a true current detection
function, as opposed to VCC voltage drop detection, as
usually implemented in ICC interface ICs.
The VDD voltage fault has a threshold voltage that can be
adjusted with an external resistor or resistor network. It
allows automated card deactivation at a customized VDD
voltage threshold value. It can be used, for instance, to
match the system controller operating voltage range.
APPLICATIONS
Set-Top-Box Conditional Access and Pay-per-
View
