Smart Card Interface
General Description
The DS8113 smart card interface is a low-cost, analog
front-end for a smart card reader, designed for all ISO
www7.8d1a6ta,sEhMeeVt™4u, .acnodmGSM11-11 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
[email protected] regarding requirements for
other microcontroller platforms. An evaluation kit,
DS8113-KIT, is available to aid in prototyping and
evaluation.
