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 o n the ST19X produc t family
and includes on-chip memories: User ROM, User
RAM and EEPROM with state of the art security
featur es. ROM, RAM and EEPROM memo ries 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
or during the life of the product.

USER ROM
The chip includes an Enhance d DES accelerator
which is accessible via cryptographic s oftware libraries 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 (MA P) and
enhanced DES accelerator are designed to speed
up cryptographic calculations using Public Key Algorithms and Secret Key Algorithms.
An RF Inteface including an RF Universal Asychornous Receiver Transmitter (UART) enables
contactless communication up to 848 Kbits/s compatible with the ISO 14443-N standard.
As with all the other S T19W products, a serial interface fully compatible with the ISO7816 standard
for Smartcard applications is available.
A CRC calculation block is also available and i s directly accessible by the User.
