DS8023 Smart Card Interface General Description Features The DS8023 smart card interface IC is a low-cost, low- Analog Interface and Level Shifting for IC Card power, analog front-end for a smart card reader designed Communication for all ISO 7816, EMV*, and GSM11-11 applications. The 8kV (min) ESD (IEC) Protection on Card Interface DS8023 supports 5V, 3V, and 1.8V smart cards, and pro- Pins vides an option for ultra-low stop-mode power consump- tion. The DS8023 is available in 28-pin TSSOP and SO Ultra-Low Stop-Mode Current, Less Than 10nA (typ) packages, and can often be used as a replacement for Internal IC Card-Supply Voltage Generation the TDA8024 with little or no application changes. 5.0V 5%, 80mA (max) The DS8023 is designed to interface between a system 3.0V 8%, 65mA (max) microcontroller and the smart card interface, providing 1.8V 10%, 30mA (max) all power supply, protection, and level shifting required for IC card applications.
