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.
