ST40RA：8-bit MCU
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.
