Multiprotocol Dual Smart Card Interface

DS807

General Description

Features

♦ Integrated ISO 7816 UART Provides Complete

The DS8007 multiprotocol dual smart card interface is a

low-cost, dual smart card reader interface supporting

Interface/Control for Two Separate Smart Card

Devices

all ISO 7816, EMV , and GSM11-11 requirements.

Through its 8-bit parallel bus and dedicated address

selects (AD3–AD0), the DS8007 can easily and directly

connect to the nonmultiplexed byte-wide bus of a

Maxim secure microcontroller. Optionally, the parallel

bus can be multiplexed to allow direct access to the

multiplexed bus of an 80C51-compatible microcon-

troller through MOVX memory addressing.

♦ 8kV (min) ESD Protection on Card Interfaces

♦ Internal IC Card Supply Voltage Generation

5.0V 5%, 65mA (max)

3.0V 8%, 50mA (max)

1.8V 10%, 30mA (max)

♦ Automatic Card Activation, Deactivation, and Data

Communication Controlled by Dedicated Internal

Sequencer

One integrated ISO 7816 UART is multiplexed among

the interfaces to allow high-speed automatic smart card

processing with each card-possessing, independent,

variable, baud-rate capability. The card interface is con-

trolled by internal sequencers that support automatic

activation and deactivation sequencing, handling all

actions required for T = 0, T = 1, and synchronous pro-

tocols. Emergency deactivation is also supported in

case of supply dropout. A third card is supported

through the auxiliary I/O. The same set of I/O can option-

ally be used as additional serial interface for the UART.

♦ Host Interface Through an 8-Bit Parallel Bus (User-

Selectable Multiplexed or Nonmultiplexed Modes)

♦ Chip Select and Three-State Bus Allow Multiple

Devices (Card Readers and Memories) on Bus

♦ 8-Character Receive FIFO with Optional

Programmable Depth/Threshold

♦ I/O Interface Pin to External ISO 7816 UART for

Auxiliary Interface

♦ Separate Card Clock Generation (Up to 10MHz)

with 2x Frequency Doubling

The DS8007 provides all electrical signals necessary to

interface with two smart cards. The integrated voltage

converter ensures full cross-compatibility between 1.8V/

3V/5V cards and a 1.8V/3V/5V environment, and allows

operation within a 2.7V to 6V supply voltage range.

♦ Selectable Card Clock Stop High, Stop Low, or

Internally Generated 1.25MHz (for Card Power-

Down)

♦ EMV-Certified Reference Design and Evaluation

Kit Available (DS8007-KIT)
