WPCT301/NPCT501 Trusted Platform Module (TPM) Version
1.2 with I2C Interface
General Description
The Nuvoton WPCT301/NPCT501 family of single-chip
Trusted Platform Modules (TPM) is a third-generation Nu-
voton SafeKeeper device that implements the TCG ver-
sion 1.2 specification for PC-Client TPM with the addition of
a serial data interface.
The WPCT301/NPCT501 is designed to reduce system
power-up time and Trusted OS loading time. It provides a
complete platform security solution for a wide range of com-
puter systems.
