DESCRIPTION
The Teridian 73S8014RN is a single smart card (ICC) interface
circuit, firmware compatible with 8024-type devices for
configurations where only asynchronous cards must be
supported. It is derived from the 73S8024RN industry-
standard electrical interface. The 73S8014RN 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 73S8014RN interfaces with the host processor through the
same bus (digital I/Os) as the 73S8024RN, which is compatible
with any other 8024-type IC. As a result, the 73S8014RN is a
very attractive cost-reduction path from traditional 8024
ICs.
The 73S8014RN has been designed to provide full electrical
compliance with ISO 7816-3, EMV 4.0 and NDS specifications.
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 that are compatible with NDS
requirements.
The 73S8014RN 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 powered
separately by a digital power supply VDD. With its embedded
LDO regulator, the 73S8014RN 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.
APPLICATIONS
Set-Top Box Conditional Access and Pay-per-View
General purpose smart card readers
