General Description

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.

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.

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.
