IDT79R4640-133MU

Product Summary

The IDT79R4640-133MU is a low-cost member of the Integrated Device Technology, Inc. RC4000 family, targeted to a variety of performancehungry embedded applications. The IDT79R4640-133MU 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. The IDT79R4640-133MU supports a wide variety of embedded processor-based applications, such as internetworking equipment (routers, switches), office automation equipment (printers, scanners), and consumer multimedia game systems. Also, being upwardly software-compatible with the RC32300 family as well as bus- and upwardly software-compatible with the IDT RC4000 family, the RC4640 will serve in many of the same applications. And, the IDT79R4640-133MU supports applications that require integer digital signal processing (DSP) functions.
