DESCRIPTION:

The IDT7M9510/7M9514 is a Single Board Computer utilizing IDT's

79RV4640/79RC64V474 MIPS processor. This CPU Mezzanine Card is

designed for use in applications where low profile, parallel board to board

mounting is required. The 7M9510/7M9514 consists of an IDT79RV4640 /

IDT79RC64V474 processor based subsystem that can either form the core

CPU function for an embedded application, or can be an optional add-in

accelerator to a PCI based system through a PCI v2.1 compatible, PMC

Standard (IEEE P1386.1) connector.

Thecardconforms,inlengthandwidthtothestandardsinglesizePMCform

factor as specified in IEEE P1386.1, and it contains all the features required of

atypicalCPUsubsystemforembeddedprocessorapplications. Someofthese

features include: DRAM, Flash, serial ports and full PCI interrupt support.
