Trusted Platform Module 28-Pin TSSOP Tray

The ST19NP18ER28PVMK is a cost-effective Trusted Platform Module (TPM) solution. The ST19NP18ER28PVMK 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 v1.2 specifications.ST19NP18ER28PVMK is based on the ST19NP18 silicon product. The ST19NP18 is driven from the Smartcard IC ST19N platform. It is manufactured using the advanced highly reliable STMicroelectronics CMOS EEPROM technology. The ST19NP18ER28PVMK 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 ST19NP18ER28PVMK also includes a Modular Arithmetic Processor (MAP). The 1088-bit architecture of this cryptographic engine allows processing of modular multiplication, squaring and additional calculations up to 2176 bit operands. The Modular Arithmetic Processor (MAP) 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 ST19NP18ER28PVMK is specially designed in line with TCG PC Client Specific TPM Implementation Specification (TIS) referring to Intel’s LPC Specification revision 1.1.
