73S8014RN  
Smart Card Interface  
Simplifying System Integration™  
DATA SHEET  
December 2008  
APPLICATIONS  
DESCRIPTION  
Set-Top Box Conditional Access and Pay-per-View  
General purpose smart card readers  
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.  
ADVANTAGES  
NDS compliant  
All NDS frequency divider rates of 4.5, 6.75 and  
13.5MHz are supported from a 27MHz clock source  
Same advantages as the Teridian 73S80xxR family:  
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.

Card VCC 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 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.  
FEATURES  
Card Interface:  
ƒ
ƒ
ƒ
ƒ
Complies with ISO 7816-3, EMV 4.0 and NDS  
73S8014RN device supports 3V / 5V cards up to 65mA  
ISO 7816-3 Activation / Deactivation sequencer  
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.  
Automated deactivation upon hardware fault (i.e. upon  
drop on VDD power supply or card overcurrent)  
The 73S8014RN incorporates an ISO 7816-3  
ƒ
The VDD voltage supervisor threshold value (fault) can  
be externally adjusted  
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.  
ƒ
ƒ
Over-current detection 130mA max  
Card CLK clock frequency up to 20MHz  
System Controller Interface:  
ƒ
3 Digital inputs control the card activation / deactivation,  
card reset and card voltage  
2 Digital inputs control the card clock frequency  
ƒ
ƒ
1 Digital output, interrupt to the system controller,  
reports to the host the card presence and faults  
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.  
ƒ
Regulator Power Supply:  
ƒ
ƒ
4.75V to 5.5V (EMV 4.0)  
4.85V to 5.5V (NDS)  
Digital Interfacing: 2.7V to 5.5V  
6kV ESD protection on the card interface  
Package: SO 20-pin  
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.  
RoHS compliant (6/6) lead-free package
