73S8024RN-32IM/F集成電路（IC）的專用規(guī)格書PDF中文資料

DESCRIPTION

The Teridian 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.

FEATURES

? Card Interface:

? Complies with ISO-7816-3, EMV 4.0 and NDS

? A 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

? 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**

? 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

? System Controller Interface:

? 3 Digital inputs control the card activation /

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.

? Crystal oscillator or host clock, up to 27MHz

? Regulator Power Supply:

? 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: SO28, 20QFN or 32QFN

APPLICATIONS

? Set-Top-Box Conditional Access and Pay-per

View

? Point of Sales and Transaction Terminals

? Control Access and Identification
