Smart Card Interface

General Description

Features

The DS8113 smart card interface is a low-cost, analog

front-end for a smart card reader, designed for all ISO

7816, EMV™, and GSM11-11 applications. The DS8113

supports 5V, 3V, and 1.8V smart cards. The DS8113

provides options for low active- and stop-mode power

consumption, with as little as 10nA stop-mode current.

o Analog Interface and Level Shifting for IC Card

Communication

o 8kV (min) ESD (IEC) Protection on Card Interface

o Ultra-Low Stop-Mode Current, Less Than 10nA

Typical

The DS8113 is designed to interface between a system

microcontroller and the smart card interface, providing

all power supply, ESD protection, and level shifting

required for IC card applications.

o Internal IC Card Supply-Voltage Generation:

5.0V 5ꢀ, 80mA (maꢁ)

3.0V 8ꢀ, ꢂ5mA (maꢁ)

1.8V 10ꢀ, 30mA (maꢁ)

An EMV Level 1 certified library (written for the MAXQ2000

microcontroller) and hardware reference design is

available. Contact Maxim technical support at

micro.support@maxim-ic.com regarding requirements for

other microcontroller platforms. An evaluation kit,

DS8113-KIT, is available to aid in prototyping and

evaluation.

o Automatic Card Activation and Deactivation

Controlled by Dedicated Internal Sequencer

o I/O Lines from Host Directly Level Shifted for

Smart Card Communication

o Fleꢁible Card Clock Generation, Supporting

Eꢁternal Crystal Frequency Divided by 1, 2, 4, or 8

Applications

Consumer Set-Top Boxes

Access Control

o High-Current, Short-Circuit and High-Temperature

Protection

o Low Active-Mode Current
