This is preliminary information on a new product now in development or undergoing evaluation. Details are subject to change without notice.
DESCRIPTION
The STPC Atlas integrates a standard 5th genera-
tion x86 core along with a powerful UMA graphics/
video chipset, support logic including PCI, ISA,
Local Bus, USB, UIDE controllers and combines
them with standard I/O interfaces to provide a sin-
gle PC compatible subsystem on a single device,
suitable for all kinds of terminal and industrial ap-
pliances.
