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 reli-
able ST CMOS EEPROM technology.
It is based on the STMicroelectronics 8 bit CPU al-
ready 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 ac-
cess rules.
An additional ST ROM contains all ST provided
functions and libraries.
Access from any memory area to another are pro-
tected by hardware FIREWALLS. Access rules are
User defined and can be selected by mask op-
tions.
The chip includes a DES accelerator which is ac-
cessible via cryptographic software libraries locat-
ed in ST ROM.
As with all the other ST19W products, a serial in-
terface fully compatible with the ISO7816 standard
for Smartcard applications is available.
A CRC calculation block is also available and is di-
rectly accessible by the User.

SOFTWARE DEVELOPMENT
Software development and firmware generation
(ROM and options) are supported by a compre-
hensive set of development tools, dedicated at de-
velopment and validation of softwares:
Smartcard ICs Emulator,
ST19X simulation package,
ScDevTools pack environment for all
Windows
TM
based stations,
Powerful C/C++ compiler and debugger are
also available (third party tools).
RF contactless demokit based upon ISO
14443 type B standard.
