st19sf02 2/ 3 hardware description the st19sf02, 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 st19sf02 is based on a stmicrolectronics 8- bit cpu and includes on chip memories: user rom, user ram and user eeprom with state of the art security features. rom, ram and eeprom memories can be con- figured into partitions with customized access rules. access from any memory area to another is protected by hardware firewalls. access rules are user defined and can be select- ed by mask options or during the life of the prod- uct. it is manufactured using the highly reliable st cmos eeprom submicron technology. as with all the other st19 family members, it is ful- ly compatible with the iso 7816 standards for smartcard applications. software development software development and firmware (rom code/ options) generation are completed by the st19- hdsx development system. figure 2. block diagram scp 126av1 internal bus system memory access firewall clk reset vcc i/o gnd rom firewall user ram user eeprom user rom system rom clock genera- tor module 8 bit timer security & configuration administrator unpre- dictable number generator serial i/o inter- face 8-bit cpu
