The ST19SF32 is based on a STMicroelectronics 8 bit CPU core including on-chip memories: 960 Bytes of RAM, 32 KBytes of USER ROM and 32 K Bytes of EEPROM. RAM, ROM and EEPROM memories can be configured into partitions. Access rules from any memory partition to another partition are setup by the user defined Memory Access Control Logic. It is manufactured using the highly reliable ST submicron technology. As all other ST19 family members, it is fully patible with the ISO standards for Smartcard applications. SOFTWARE DEVELOPMENT Software development and firmware (ROM code/ options) generation are pleted by the ST16-19 HDS development system. Figure 1.
