Fax: (+33) 4 42 68 87 29 1/2 1 HARDWARE DESCRIPTION The ST19XG34, a member of the ST19 platform, is a serial access microcontroller especially designed for very large volume and cost effective secure portable applications. The ST19XG34 is based on a STMicrolectronics 8 bit CPU and includes on chip memories: 70 K User ROM, 2016-byte User RAM and 34K User EEPROM with state of the art security features. ROM, RAM and EEPROM memories can be configured into partitions with customized access rules. Figure 2 Block diagram Access from any memory area to another are protected by hardware FIREWALLS. Access rules are User defined and can be selected by mask options or during the life of the product. The chip includes a DES accelerator which is accessible via a cryptographic system ROM software library. A CRC calculation block is also available and is directly accessible by the User. This product is manufactured using an advanced highly reliable ST CMOS EEPROM technology. As with all the other ST19 products, it is fully compatible with the ISO7816 standard for Smartcard applications.
