2 / 2 page ST19AF08 2/2 HARDWARE DESCRIPTION The ST19AF08, a member of the ST19 device family, is a serial access microcontroller especially designed for very large volume and cost competi- tive secure portable objects. The ST19AF08 is based on a STMicroelectronics 8 bit CPU core including on-chip memories: 960 Bytes of RAM, 32 K Bytes of USER ROM and 8 K Bytes of EEPROM. RAM, ROM and EEPROM memories can be con- figured 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 technology. As all other ST19 family members, it is fully com- patible with the ISO standards for Smartcard appli- cations. SOFTWARE DESCRIPTION Software development and firmware (ROM code/ options) generation are completed by the ST16-19 HDSE development system. Figure 1.
