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 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.

Note 1: Operation guaranteed at -40°C and +85°C but not tested. Note 2: IDD_IC measures the amount of current used by the DS8113 to provide the smart card current minus the load. Note 3: Stop mode is enabled by setting CMDVCC, 5V/3V, and 1_8V to a logic-high. Note 4: Parameters are guaranteed to meet all ISO 7816, GSM11-11, and EMV 2000 requirements. For the 1.8V card, the maximum

rise and fall time is 10ns.

Note 5: Parameter is guaranteed to meet all ISO 7816, GSM11-11, and EMV 2000 requirements. For the 1.8V card, the minimum

slew rate is 0.05V/µs and the maximum slew rate is 0.5V/µs.
