Overview
The ST40RA is the first member of the ST40 family. Based
on the SH-4, SuperH CPU core from SuperH Inc, the
ST40RA is designed to work as a standalone device, or as
part of a two chip solution for application specific systems.
Example applications the ST40RA is designed for include
digital consumer, embedded communications, industrial
and automotive. The high connectivity of the ST40 through
its PCI bus and its dual memory uses makes it a versatile
device, ideal for data-intensive and high performance
applications.
