The AT90SC6464C-USB from Atmel is an AVR-based secure Flash microcontroller with a USB full-speed interface combined with the AVR 8/16-bit RISC core, powerful cryptography capabilities and a high level of security. The USB V1.1 full speed interface (12Mbps) gives it a direct high-speed connection to any PC or Internet appliance using e-Token or Smart Card support.
It is no longer necessary to install a traditional SC reader on the PC, only a low cost connector. The AT90SC6464C-USB has a dual USB/ISO 7816 external interface that is automatically configured on insertion into a reader. In this way, it remains compatible with the established ISO 7816 infrastructure, while opening up all the possibilities of USB interfacing.
The AVR 8-bit RISC processor has 64Kbytes of on-chip Flash memory and 64Kbytes of EEPROM. The AT90SC6464C-USB includes all the security features already built into the AT90SC series, in particular a 16-bit RISC crypto-processor for efficient hardware accelerated execution of highest-level encryption algorithms.
