ST19WP18

form
Module (TPM) solution. The ST19WP18 is
designed to provide PC platforms with enhanced
security and integrity mechanisms as defined by
Trusted Computing Group standards. The product
provides full support of TCG v1.1b as well as TCG
v1.2 specifications
The ST19WP18 is driven from the Smartcard IC ST19W platform. It is manufactured using the advanced highly reliable STMicroelectronics CMOS EEPROM technology.

The ST19WP18 has an 8-bit CPU architecture and includes the following 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 access rules.

The ST19WP18 also includes a Modular Arithmetic Processor (MAP). The 1088 bits architecture of this cryptographic engine allows processing of modular multiplication, squaring and additional calculations up to 2176 bit operands.

The Modular Arithmetic Processor is designed to speed up cryptographic calculations using Public Key Algorithms.

The Secure Hash Accelerator allows fast SHA-1 computation especially well suited for BIOS hash operations during early boot stages.

The ST19WP18 has been specially designed in line with TCG PC Client Specific TPM Implementation Specification (TIS) referring to Intel's LPC Specification revision 1.0.
