产品概述
描述
The ST19NP18-TPM-I2C is a cost-effective Trusted Platform Module (TPM) solution. The ST19NP18-TPM-I2C is designed to provide embedded platforms with enhanced security and integrity mechanisms as defined by Trusted Computing Group standards. The product provides full support of TCG v1.2 specifications.
The ST19NP18-TPM-I2C is based on the ST19NP18 silicon product and includes an I²C communication interface (Slave mode).
The ST19NP18 is driven from the Smartcard IC ST19N platform. It is manufactured using the advanced highly reliable STMicroelectronics CMOS EEPROM technology.
The ST19NP18 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 ST19NP18 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.
