IDT79RC64V475-200DP

Description

The IDT79RC4640 is a low-cost member of the Integrated Device Technology, Inc. RC4000 family, targeted to a variety of performancehungry embedded applications. The RC4640 continues the RC4000 tradition of high-performance through high-speed pipelines, high-bandwidth caches and bus interface, 64-bit architecture, and careful attention to efficient control. The cost of this performance is reduced by removing functional units frequently not required for many embedded applications.
