DS8023-RJX+

DS8023-RJX+ is a smart card interface IC. This low-cost, low-power, analogue front-end for a smart card reader is designed for all ISO 7816, EMV, and GSM11-11 applications. It supports 5V, 3V, and 1.8V smart cards, and provides an option for ultra-low stop-mode power consumption. It 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. It is used in applications such as set-top box conditional access, access control, banking applications, POS terminals, debit/credit payment terminals, PIN pads, automated teller machines, telecommunications, and pay/premium television.

• Analog interface and level shifting for IC card communication
• ±8kV (min) ESD (IEC) protection on card interface pins
• Automatic card activation and deactivation controlled by dedicated internal sequencer
• I/O lines from host directly level shifted for smart card communication
• High-current/short-circuit and high-temperature protection
• Digital supply voltage range from 2.7V to 6.0V
• Card-voltage-generator supply voltage range from 4V to 6V
• Crystal frequency is 20MHz maximum at (VDD = +3.3V, VDDA = +5.0V, TA = +25°C)
• Internal oscillator (clock source) is 2.7MHz typical at (VDD = +3.3V, VDDA = +5.0V, TA = +25°C)
• Operating temperature range from -40°C to +85°C, 28-pin TSSOP package
