NPCT42xC

NPCT42x Trusted Platform Module (TPM) Preliminary March 2011 Revision 1.1 NPCT42x Trusted Platform Module (TPM) General Description The NPCT42x single-chip Trusted Platform Module (TPM) is a family of third-generation, Nuvoton SafeKeeper technology 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. Bus Interface ■ LPC Bus Interface — Based on Intel’s LPC Interface Specification Revision 1.1, August 2002 — TPM 1.2 Interface (TIS) Clocking and Supply ■ ■ On-Chip Clock Generator Power Supply — 3.3V supply operation — Separate pins for main (VDD) and standby (VSB) power supplies — Low standby power consumption Features General ■ Single-chip TPM solution — No external parts required Compatible with TPM Main Specification Version 1.2 Revision 116 and PC Client Specific TPM Interface Specification Version 1.21 Revision 72 Host Interface — TPM 1.2 standard interface (TIS) with five localities — Supports legacy locality by using TIS protocol with I/O mapped registers Secure General-Purpose I/O (GPIO) — Five GPIO pins — I/O pins individually configured as input or output — Configurable internal pull-up resistors — TCG 1.2-defined interface...
