73S8014R
Smart Card Interface
Simplifying System Integration™
DATA SHEET
September 2008
DESCRIPTION
The Teridian 73S8014R 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 73S8014R has been
optimized to match most of the typical Set-Top-Box / A/V
Conditional Access applications. Optimization essentially
involved a smaller pin-count, support for single I/O, and
maximum card current of 65mA (ISO-7816 / EMV
compliance).
The 73S8014R 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
73S8014R is a very attractive cost-reduction path from
traditional 8024 ICs.
The 73S8014R has been designed to
provide full electrical compliance with ISO 7816-3 and EMV
4.0 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.
The 73S8014R 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 V
PC
. Digital
circuitry is powered separately by a digital power supply V
DD
.
With its embedded LDO regulator, the 73S8024RN 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 (V
DD
). The card over-current circuitry is a true
current detection function, as opposed to V
CC
voltage drop
detection, as usually implemented in non-Teridian 8024
interface ICs.
The V
DD
voltage fault has a threshold voltage that can be
adjusted with an external resistor network. It allows
automated card deactivation at a customized V
DD
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
ADVANTAGES
Same advantages as the Teridian 73S80xxR family:
VCC card generated by an LDO regulator
Very low power dissipation (saves up to 1/2W)
Fewer external components are required
Better noise performance
True card over-current detection
Firmware compatibility with all 8024 ICs
Small format 20SO package
