The 73S8009CN is the industry’s first single-chip smart card electrical interface circuit that supports all types of smart cards: 5V, 3V and 1.8V, including traditional ISO 7816-3 asynchronous and synchronous Type 1 and Type 2, as well as USB, ISO 7816-12 cards. The 73S8009CN is ideally suited for applications such as desktop computers, laptops, and general-purpose smart card readers that require low power operation from a single 2.7V to 6.5V power-supply voltage source. A power-down mode (“OFF” mode) is available and exhibits a 10nA typical current consumption. Applications * Desktop Computers * General-Purpose Smart Card Readers Requiring Low Power Operation from a Single 2.7V to 6.5V Power-Supply Voltage Source * Laptops * Compliance with Key Standards: ISO 7816-3, EMV 4.1, ISO 7816-12 (USB), NDS * USB Card Support * Drives C4 and C8 Smart Card Signals to D+ and D- USB Lines to the Host Processor * Power Supply and Power Management * Single Power Supply (+2.7V to +6.5V Range)
