2 / 4 page ST19WR02 2/4 Hardware description The product, member of the ST19W platform, is a serial access microcontroller specially designed for cost-effective secure portable applications. It is manufactured using an advanced highly reliable ST CMOS EEPROM technology. It is based on the STMicroelectronics 8-bit CPU already implemented on the ST19X product family and includes on-chip memories: User ROM, User RAM and EEPROM with state-of-the-art security features. ROM, RAM and EEPROM memories can be configured into partitions with customized access rules. An additional ST ROM contains all ST provided functions and libraries. Access from any memory area to another are protected by hardware firewalls. Access rules are user- defined and can be selected by mask options. The chip includes a DES accelerator which is accessible via cryptographic software libraries located in ST ROM. As with all the other ST19W products, a serial interface fully compatible with the ISO 7816 standard for Smartcard applications is available. A CRC calculation block is also available and is directly accessible by the User.
