Atmel ships single-chip secure USB MCU

Atmel Corp. is sampling a single chip USB full-speed secure microcontroller encased in a PQFP44 package. The AT90SC6464C-USB-I is based on the company's secureAVR RISC microcontroller and requires no external clock.

The device is targeted at eTokens used in PC-based secure applications and can also be embedded in peripherals, STBs, modems, PDAs, and copyright protection devices. The microcontroller provides these applications with transactional security, e-mail and network encryption, and software and file protection.

It includes 64KB each of on-chip Flash memory and EEPROM. Dual communication interfaces, including both USB V2.0 Full-Speed (12Mbps) and ISO 7816, are also included.

The AT90SC6464C-USB-I includes all the security features already built into the AT90SC secure microcontroller series. It provides a 16-bit RISC crypto processor for efficient execution of the encryption algorithms such as RSA, AES 128/128, and SHA-256. In addition, a hardware Triple Data Encryption Standard coprocessor and a true Random Number Generator are included, with support for Elliptic Curve Cryptography.

"The AT90SC6464C-USB-I gives customers the advantage of a USB V2.0 Full-Speed interface in a high-end secure chip while getting a cost-effective solution that requires no external USB clock," said Herve Roche, Atmel's Smart Card IC Marketing Manager, stated.
