DS8023 smart card interface IC
Maxim release DS8023 smart card interface IC which is a low-cost , low power, analog front-end for a smart card reader designed for all ISO 7816, EMV*, and GSM11-11 applications.
The DS8023 supports 5V, 3V, and 1.8V smart cards, and provides an option for ultra-low stop-mode power consumption and is available in 28-pin TSSOP and SO packages .
The DS8023 is designed to interface between a system microcontroller and the smart card interface, providing all power supply, protection, and level shifting required for IC card applications and can often be used as a replacement for the TDA8024 with little or no application changes.
Main features of DS8023 are : Analog Interface and Level Shifting for IC Card Communication , ±8kV (min) ESD (IEC) Protection on Card Interface Pins , Ultra-Low Stop-Mode Current, Less Than 10nA (typ) , Internal IC Card-Supply Voltage Generation , 5.0V ±5%, 80mA (max) 3.0V ±8%, 65mA (max) 1.8V ±10%, 30mA (max) , Automatic Card Activation and Deactivation Controlled by Dedicated Internal Sequencer , I/O Lines from Host Directly Level Shifted for Smart Card Communication , Flexible Card Clock Generation, Supporting , External Crystal Frequency Divided by 1, 2, 4, or 8 ; High-Current/Short-Circuit and High-Temperature Protection
This circuit can be used in applications like : Set-Top Box Conditional Access , Access Control , Banking Applications , POS Terminals , Debit/Credit Payment Terminals , PIN Pads , Automated Teller Machines Telecommunications , Pay/Premium Television , etc.
