Revision 1.0
PC8392T
SafeKeeperTM Notebook TrustedI/O with TPM 1.1b
General Description
The PC8392T, a member of the Winbond TrustedI/O
family, is targeted for a wide range of notebook applications.
PC8392T integration allows for a reduced system board
size, reduced system current consumption, and saves on
total system cost.
This device includes a SafeKeeperTrusted Platform Mod-
ule (TPM), legacy SuperI/O functions, commonly used func-
tions such as GPIO, and ACPI-compliant Power Manage-
ment support.
The TPM provides a solution for PC security, based on the
TCG standard. The complete security solution includes
hardware, software, and firmware.
The Winbond PC8392T and PC87374T use the same TPM,
enabling a single TCG-based security solution across note-
book and desktop systems.
The PC8392T is pin and software compatible with the
PC87392. This provides drop-in interchangeability using
only a single motherboard and BIOS.
The PC8392T supports both I/O and memory mapping of
module registers and enables building legacy-free systems.
