73S8014RT  
Smart Card Interface  
Simplifying System Integration™  
DATA SHEET  
December 2008  
DESCRIPTION  
APPLICATIONS  
Set-Top Box Conditional Access and Pay-per-  
View  
General purpose smart card readers  
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.  
ADVANTAGES  
Same advantages as the Teridian 73S80xxR  
Optimization essentially involved a smaller pin-count  
and support for single I/O.  
family:  
ƒ Card VCC generated by an LDO regulator  
ƒ Very low power dissipation (saves up to 1/2W)  
ƒ Fewer external components are required  
ƒ Better noise performance  
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.  
True card over-current detection  
Small format 20SO package  
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.  
FEATURES  
Card Interface:  
ƒ Complies with ISO 7816-3, EMV 4.0  
ƒ 73S801RT device supports 3V / 5V cards up to  
The 73S8014RT incorporates an ISO 7816-3  
65mA and 1.8V up to 40mA  
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.  
ƒ ISO 7816-3 Activation / Deactivation sequencer  
ƒ Automated deactivation upon hardware fault (i.e.  
upon drop on VDD power supply or card  
overcurrent)  
ƒ The VDD voltage supervisor threshold value (fault)  
can be externally adjusted  
ƒ Over-current detection 130mA max  
ƒ Card CLK clock frequency up to 20MHz  
System Controller Interface:  
ƒ 3 Digital inputs control the card activation /  
deactivation, card reset and card voltage  
ƒ 2 Digital inputs control the card clock frequency  
ƒ 1 Digital output, interrupt to the system controller,  
reports to the host the card presence and faults  
ƒ Crystal oscillator or host clock, up to 27MHz  
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.  
Regulator Power Supply:  
ƒ 4.75V to 5.5V (EMV 4.0)  
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.  
Digital Interfacing: 2.7V to 5.5V  
6kV ESD protection on the card interface  
Package: SO 20-pin  
RoHS compliant (6/6) lead-free package
