NPCT42x Trusted Platform Module (TPM)
Preliminary
March 2011
Revision 1.1
General Description
The NPCT42x single-chip Trusted Platform Module (TPM) is
a family of third-generation, Nuvoton SafeKeeper technolo-
gy devices. The devices implement the Trusted Computing
Group (TCG) version 1.2 specifications for PC-Client TPM.
The NPCT42x devices are designed to reduce system boot
time and Trusted OS loading time. They provide a solution
for PC security for a wide range of PC applications.
The NPCT42x family of devices are Microsoft Windows
compliant and are supported by Linux kernel v2.6.18 and
higher.
