Secure microcontroller for smartcard
STMicroelectronics
It is based on an enhanced STMicroelectronics 8/16-bit CPU core offering 16 Mbytes linear addressing space. It is manufactured using an advanced highly reliable ST CMOS EEPROM technology.
The ST23YT66 is a secure USB microcontroller based on the ST23 core architecture. Its high security level and versatile communication interfaces address user identification functions for computer or network access or for computer-based local or remote applications.
The ST23YT66 features a USB full-speed interface for communication with computers as well as various I/Os and an SPI bus for user interfaces (keyboards, displays, etc.).
The ST23YT66 USB hardware accelerator provides a very efficient AutoPlay mode implementation. This enables the content of a companion serial Flash memory to be uploaded to a computer at a speed close to USB bandwidth.
