8009CN
The 73S8009x circuits are transparent electrical interfaces that allow a host processor to communicate with all types of smart cards. A transparent interface implies that an image of each smart card signal is provided by the interface to the host processor and translated to the appropriate digital level. This configuration provides full control to the host of the card management and card activation / deactivation. Additionally, the architecture reduces die size to a minimum, making the 73S8009x circuits the most cost-effective on the market. The 73S8009CN implements a DC-DC converter thus requiring a single power supply whose voltage range can be as wide as +2.7V to +6.5V.
The 73S8009CN is the world's first interface capable of supporting both ISO-7816-3 signal cards and ISO-7816-12 USB cards. In both cases, the host processor is responsible for handling the ISO-7816-3 UART and ISO-7816-12 USB engine (and associated protocol layers).
