DS8113

Smart Card Interface

Smart Card Interface Provides Robust Communication with Industry's Lowest Stop-Mode Current


Please check latest availability status for a specific part variant.

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 library (written for the MAXQ2000 microcontroller) and hardware reference design is available. Contact Maxim technical support at www.maximintegrated.com/support regarding requirements for other microcontroller platforms. An evaluation kit, DS8113-KIT, is available to aid in prototyping and evaluation.
