HARDWARE DESCRIPTION
The ST19XG34, a member of the ST19 platform,
is a serial access microcontroller especially de-
signed for very large volume and cost effective se-
cure portable applications.
The ST19XG34
is based on a STMicrolectronics 8
bit CPU and includes on chip memories: 70 K
User ROM, 2016-byte User RAM and 34K User
EEPROM with state of the art security features.
ROM, RAM and EEPROM memories can be con-
figured into partitions with customized access
rules.
Figure 2 Block diagram
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 or during the life of the product.
The chip includes a DES accelerator which is ac-
cessible via a cryptographic system ROM soft-
ware library.
A CRC calculation block is also available and is di-
rectly accessible by the User.
This product is manufactured using an advanced
highly reliable ST CMOS EEPROM technology.
As with all the other ST19 products, it is fully com-
patible with the ISO7816 standard for Smartcard
applications.
SOFTWARE DEVELOPMENT
Software development and firmware (ROM code/
options) generation are done with the ST19-HDSX
development system, on Windows NT and Win-
dows 98. Powerfull C/C++ compiler, debugger
and simulator are also available.
SYMMETRICAL ALGORITHMS
:
– DES, triple DES, DESX computations
– CBC chaining mode
– Loading / Unloadings from / to registers are se-
cured against SPA
