HARDWARE DESCRIPTION
The product, member of the ST19W platform, is a
serial access microcontroller specially designed
for cost effective secure portable applications.
It is manufactured using an advanced highly reliable ST CMOS EEPROM technology.
It is based on the STMicroelectronics 8 bit CPU already implemented on the ST19X product family
and includes on-chip memories: User ROM, User
RAM and EEPROM with state of the art security
features. ROM, RAM and EEPROM memories can
be configured into partitions with customized access rules.
An additional ST ROM contains all ST provided
functions and libraries.
Access from any memory area to another are protected by hardware FIREWALLS. Access rules are
User defined and can be selected by mask options.
The chip includes an Enhanced DES accelerator
which is accessible via cryptographic software libraries located in ST ROM.
As with all the other ST19W products, a serial interface fully compatible with the ISO7816 standard
for Smartcard applications is available.
A CRC calculation block is also available and is directly accessible by the User.
