73S8024RN  
Low-Cost Smart Card Interface  
DATA SHEET  
ADVANTAGES  
DESCRIPTION  
Traditional step-up converter is replaced by a LDO  
regulator:  
The 73S8024RN is a single smart card (ICC) interface IC  
that can be controlled by a dedicated control bus. The  
73S8024RN has been designed to provide full electrical  
compliance with ISO 7816-3, EMV 4.0 (EMV2000) and  
NDS specifications.  
Greatly reduced power dissipation  
Fewer external components are required  
Better noise performance  
High current capability (90mA supplied to the card)  
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.  
SO28 package is pin-to-pin compatible with  
industry-standard TDA8004 and TDA8024  
Card clock STOP (high and low) mode  
Small format (4x4x0.85mm) 20QFN package option  
True card over-current detection  
The card clock can be generated by an on-chip oscillator  
using an external crystal or by connection to a clock  
signal.  
FEATURES  
Card Interface:  
The 73S8024RN 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  
. Complies with ISO 7816-3, EMV 4.0, and NDS  
. An LDO voltage regulator provides 3V / 5V to the  
card from an external power supply input  
. Provides at least 90mA to the card  
. ISO 7816-3 Activation / Deactivation sequencer with  
emergency automated deactivation on card removal  
or fault detected by the protection circuitry  
VPC. Digital circuitry is separately powered 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.  
Hardware support for auxiliary I/O lines, C4 / C8 contacts,  
is provided*.  
. Protection includes 3 voltage supervisors that detect  
voltage drops on VCC (card), VDD (digital)**, and VPC  
(regulator) power supplies  
. The VDD voltage supervisor threshold value can be  
externally adjusted**  
Emergency card deactivation is initiated upon card  
extraction or upon any fault generated by the protection  
circuitry. The fault can be a card over-current, a VDD  
(digital power supply)**, a VPC (regulator power supply), a  
VCC (card power supply) or an over-heating fault.  
. Over-current detection 150mA max  
. Card clock stop high or low*  
. 2 card detection inputs, 1 for each possible user  
polarity  
. Auxiliary I/O lines, for C4 / C8 contact signals*  
. Card CLK clock frequency up to 20MHz  
The card over-current circuitry is a true current detection  
function, as opposed to VCC voltage drop detection, as  
usually implemented in ICC interface ICs.  
System Controller Interface:  
. 3 Digital inputs control the card activation /  
The VDD voltage fault has a threshold voltage that can be  
adjusted with an external resistor or 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.  
deactivation, card reset and card voltage  
. 4 Digital inputs control the card clock (division rate  
and card clock stop modes)  
. 1 Digital output, interrupt to the system controller,  
allows the system controller to monitor the card  
presence and faults.  
APPLICATIONS  
. Crystal oscillator or host clock, up to 27MHz
