ST19RF08
HARDWARE DESCRIPTION
The ST19RF08, a member of the ST19 device
family, is a serial access microcontroller especially
designed for very large volume and cost competitive secure portable objects.
The ST19RF08 is based on a S TM icroele ctronics
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 configured into partitions. Access rules from any
memory partition to another partition are s etup by
the user defined Memory Access Control Logic.
Figure 1 Block Diagram
It is manufactured using the highly reliable ST submicron technology.
As all o ther ST19 f am ily m emb ers, it is fully co mpatible with the ISO standards for Smartcard applications:
– ISO7816 for contact operation,
– ISO14443 for contactless operation.
SOFTWARE DEVELOPMENT DESCRIPTION
Software development and firmware (ROM code/
options) generation are completed by the ST16-19
HDSE development system.
