DS8113-RNG+

P1-P3P4-P6P7-P9P10-P12P13-P15P16-P17
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 library (written for the MAXQ2000
microcontroller) and hardware reference design is
available. Contact Maxim technical support at
https://support.maxim-ic.com/micro
regarding
requirements for other microcontroller platforms. An
evaluation kit, DS8113-KIT, is available to aid in proto-
typing and evaluation.
