关于AT88SC0404C单片机
The AT88SC0404C provides high security, low cost, and ease of implementation without the need for a microprocessor operating system. The embedded cryptographic engine provides for dynamic, symmetric-mutual authentication between the device and host, as well as performing stream encryption for all data and passwords exchanged between the device and host. Up to four unique key sets may be used for these operations.
The AT88SC0404C offers the ability to communicate with virtually any smart card reader using the asynchronous T = 0 protocol (Gemplus Patent) defined in ISO 7816-3.
