Description ST21Y068 1 Description The ST21Y068 product is a serial access microcontroller specially designed for costeffective secure mobile applications. 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 device includes a DES accelerator. A serial interface fully compatible with the ISO 7816-3 standard (T = 0 and T = 1) for Smartcard applications is available. A CRC calculation block is also available and is directly accessible by the User. The product architecture is optimized for low power consumption applications. A flexible clock generator module provides increased performance for specific current requirements. Figure 1.

The range of tools includes solutions to help you to develop and debug your application and evaluate smartcard products and their peripherals. An Integrated Development Environment (IDE), the STMicroelectronics Visual Debug (STVD), provides a set of tools for developing embedded applications. This interface manages the project configuration, code edition, code generation and program debugging. An emulator (SCICS) and a simulator are available for developing and validating your application code. All the information needed to generate the application code and personalization will be collected in a delivery file (.DLV extension). This file is created using the Delivery menu of the STMicroelectronics configuration software tool, SCOOL. 2 Revision history Table 1.
