DS8113 19-5216 Rev 3 4/10 Smart Card Interface General Description Features The DS8113 smart card interface is a low-cost, analog Analog Interface and Level Shifting for IC Card front-end for a smart card reader, designed for all ISO Communication 7816, EMV, and GSM11-11 applications. The DS8113 8kV (min) ESD (IEC) Protection on Card Interface supports 5V, 3V, and 1.8V smart cards. The DS8113 provides options for low active- and stop-mode power Ultra-Low Stop-Mode Current, Less Than 10nA consumption, with as little as 10nA stop-mode current. Typical The DS8113 is designed to interface between a system Internal IC Card Supply-Voltage Generation: microcontroller and the smart card interface, providing 5.0V 5%, 80mA (max) all power supply, ESD protection, and level shifting 3.0V 8%, 65mA (max) required for IC card applications. 1.8V 10%, 30mA (max) An EMV Level 1 library (written for the MAXQ2000 Automatic Card Activation and Deactivation microcontroller) and hardware reference design is available.
