STMicroelectronics migrates to 0.15-micron process technology
The new ST19NP18 is based on the successful previous-generation ST19WP18 TPM, with the 0.15-micron process delivering additional cost benefits for PC manufacturers.Embedded in a computer system motherboard, the TPM provides secure storage for keys, passwords and digital certificates, to enable platform validation, core root of trust, and management of user credentials.
The TPM can be used to verify that hardware is unchanged and that the BIOS has not been compromised. ST has shipped several million TPM devices to leading desktop and laptop computer manufacturers which have deployed the devices since the beginning of 2006.
Conforming to the most up-to-date version of the TCG TPM specification, version 1.2, the ST19NP18-TPM also supports a highly secure Field Upgrade capability, to enable upgrades to future TCG specifications; to implement enhanced security countermeasures based on new security policies; and to react to newly-identified security threats.
The upgrade mechanism takes full advantage of the product's hardware security features and a Public Key Infrastructure.
