HARDWARE DESCRIPTION
The product, member of the ST19X platform, is a
serial access microcontroller specially designed
for cost effective secure portable applications.
It is manufactured using an advanced highly relia-
ble ST CMOS EEPROM technology.
It is based on a STMicrolectronics 8 bit CPU and
includes on chip memories: 48KBytes User ROM,
1.5KBytes User RAM and 4KBytes EEPROM with
state of the art security features. ROM, RAM and
EEPROM memories can be configured into parti-
tions with customized access 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
accessible via cryptographic software library lo-
cated in ST ROM.
As with all the other ST19X products, a serial in-
terface fully compatible with the ISO7816 stand-
ard for Smartcard applications is available.
A CRC calculation block is also available and is di-
rectly accessible by the User.
