STMicroelectronics ST40RA
The ST40RA is the first member of the ST40 family. 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. 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.| Part No. | ST40RA |
