DESCRIPTION
The Teridian 73S8014RT is a single smart card (ICC)
interface circuit. It is derived from the 73S8024RN
industry-standard electrical interface but adds support
for 1.8V smart card applications. The 73S8014RT has
been optimized to match most of the typical Set-Top
Box / A/V Conditional Access applications.
Optimization essentially involved a smaller pin-count
and support for single I/O.
The 73S8014RT has been designed to provide full
electrical compliance with ISO 7816-3, EMV 4.0.
Interfacing with the system controller is done through a
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.
The card clock can be generated by an on-chip
oscillator using an external crystal or by connection to
an externally supplied clock signal. In addition, the
clock divider provides divisor values of divide by 1, 2, 4
and 6.
The 73S8014RT incorporates an ISO 7816-3
activation/deactivation sequencer that controls the card
signals. Level-shifters drive the card signals with the
selected card voltage (1.8V, 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 powered separately by a
digital power supply VDD. With its embedded LDO
regulator, the 73S8014RT is a cost-effective solution for
any application where a 5V (typically -5% +10%) power
supply is available.
Emergency card deactivation is initiated upon card
extraction or upon any fault detected by the protection
circuitry. The fault can be a card over-current, VCC
undervoltage or power supply fault (VDD). The card
over-current circuitry is a true current detection function,
as opposed to VCC voltage drop detection, as usually
implemented in non-Teridian 8024 interface ICs.
The VDD voltage fault has a threshold voltage that can
be adjusted with an external 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.
