73S8024RN
Low-Cost Smart Card Interface
DATA SHEET
Rev. 2

DESCRIPTION
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.
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 a clock
signal.
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
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*.
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.
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.
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.
APPLICATIONS
Set-Top-Box Conditional Access and Pay-per-
View
Point of Sales and Transaction Terminals
Control Access and Identification
* Pins/functions not available on 20-pin QFN package.
** User VDD_FLT threshold configuration not available on
20-pin QFN package.
ADVANTAGES
Traditional step-up converter is replaced by a LDO
regulator:
Greatly reduced power dissipation
Fewer external components are required
Better noise performance
High current capability (90mA supplied to the card)
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
