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 options
or during the life of the product.
The chip includes an Enhanced DES accelerator
which is accessible via cryptographic software li-
braries located in ST ROM.
The chip includes also a MAP which is based on a
1088 bits processor architecture. It processes
modular multiplication, squaring and additional
calculations up to 2176 bit operands.
Internal Modular Arithmetic Processor (MAP) and
enhanced DES accelerator are designed to speed
up cryptographic calculations using Public Key Al-
gorithms and Secret Key Algorithms.
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.

(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 environment for WindowsTM NT,
2000, XP based stations,
–
Powerful C/C++ compiler and debugger are
also available (third party tools).
