IDT79RV4640-200DU

Microprocessors Overview

The IDT79RV4640-200DU is a high-performance embedded microprocessor belonging to the ORION family, manufactured by Renesas Electronics. It features a 64-bit MIPS RISC architecture with an operating frequency of 200MHz. The device integrates a 50MFlops single-precision floating-point unit and separate 8KB instruction and data caches. It utilizes a 32-bit bus interface to balance system cost with 64-bit processing power.

Microprocessors Feature Summary

• Integrates a 64-bit integer CPU core with a dedicated floating-point unit for high-speed mathematical operations
• Includes on-chip 8KB instruction and 8KB data caches to maximize internal memory bandwidth
• Supports low-power operation through active power management that powers down inactive functional units

Microprocessors Applications

• High-performance embedded applications requiring efficient control
• Systems needing upward software compatibility with the RISController family
• Applications requiring easy upgrade paths to 64-bit systems

Microprocessors Procurement Notes

Verify the specific suffix DU against official Renesas documentation to confirm package type and temperature range. Confirm current availability status as legacy components may have limited supply or end-of-life designations. Ensure pinout compatibility with existing PCB layouts before procurement.

Microprocessors Selection Notes

Select this component when a 200MHz MIPS-compatible processor with integrated FPU is required. Consider the 32-bit bus interface if system cost constraints exist alongside 64-bit processing needs. Evaluate cache requirements against application latency specifications.

Microprocessors Part Context

This part is a member of the ORION family, designed for performance-hungry embedded environments. It maintains software compatibility with the broader RISController lineage while offering enhanced throughput via pipelining and caching technologies compared to earlier generations.

Microprocessors Replacement Considerations

Check for direct cross-references within the IDT/Renesas portfolio such as the IDT79RV4640 variants with different speed grades. Verify mechanical footprint equivalence if substituting with other QFP packages.
