HARDWARE DESCRIPTIONThe 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 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 DEVELOPMENTSoftware development and firmware (ROM code/
options) generation are completed by the ST19-
HDSX development system.
