73S8024RN
Low Cost Smart Card Interface

DESCRIPTION
The TERIDIAN 73S8024RN is a single smart card (ICC)
interface IC that can be controlled by a dedicated control bus.
The TERIDIAN 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.
TERIDIAN
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
TERIDIAN
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 & Transaction Terminals
Control Access & Identification
* Pins/functions not available on 20 pin QFN package.
** User VDD_FLT threshold configuration not available on 20 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
