73S8014R  
Smart Card Interface  
Simplifying System Integration™  
DATA SHEET  
September 2008  
DESCRIPTION  
APPLICATIONS  
Set-Top-Box Conditional Access and Pay-per-View  
General purpose smart card readers  
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).  
ADVANTAGES  
Same advantages as the Teridian 73S80xxR family:  
ƒ
ƒ
ƒ
ƒ
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  
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.  
FEATURES  
Card Interface:  
ƒ
ƒ
ƒ
ƒ
Complies with ISO 7816-3 and EMV 4.0  
Supports 3V / 5V cards  
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.  
ISO 7816-3 Activation / Deactivation sequencer  
Automated deactivation upon hardware fault (i.e. upon  
drop on VDD power supply or card overcurrent)  
The card clock can be generated by an on-chip oscillator  
using an external crystal or by connection to an externally  
supplied clock signal.  
ƒ
The VDD voltage supervisor threshold value (fault) can  
be externally adjusted  
ƒ
ƒ
Over-current detection 130mA max  
The 73S8014R incorporates an ISO 7816-3  
Card CLK clock frequency up to 20MHz  
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 73S8024RN is a  
cost-effective solution for any application where a 5V  
(typically -5% +10%) power supply is available.  
System Controller Interface:  
ƒ
3 Digital inputs control the card activation /  
deactivation, card reset and card voltage  
ƒ
ƒ
2 Digital inputs control the card clock frequency  
.
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  
Regulator Power Supply:  
4.75V to 5.5V  
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.  
ƒ
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  
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.
