Multiprotocol Dual Smart Card Interface

DS807

General Description

Features

♦ Complete Interface/Control for Two Separate

The DS8007 multiprotocol dual smart card interface is a

low-cost, dual smart card reader interface supporting

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/Dallas secure microcontroller. Optionally, the

parallel bus can be multiplexed to allow direct access

to the multiplexed bus of an 80C51-compatible micro-

controller through MOVX memory addressing.

Smart Card Devices

♦ 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 UART is multiplexed among the inter-

faces to allow high-speed automatic smart card pro-

cessing 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 Tri-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

♦ Separate Card Clock Generation (Up to 10MHz)

with 2x Frequency Doubling

♦ Selectable Card Clock STOP HIGH, STOP LOW, or

Internally Generated 1.25MHz (for Card Power-

Down)

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.

♦ EMV-Certified Reference Design and Evaluation

Kit Available (DS8007-KIT)
