71V3579S65PFG

Overview

The IDT71V3579S65PFG is a 4.5Mb synchronous single data rate SRAM organized as 256K x 18, manufactured by Renesas Electronics Corporation. It features a parallel interface with a maximum access time of 6.5 ns and operates within a supply voltage range of 3.135V to 3.465V. The component is housed in a 100-TQFP (14x20) surface-mount package and supports an operating temperature range of 0°C to 70°C.

Feature Summary

• Synchronous SDR architecture for high-speed data transfer
• Flow-through output configuration without pipeline registers
• Internal burst counter supporting four-word sequential access

Applications

• High-performance cache memory systems
• Network routing equipment buffers
• Telecommunications signal processing units

Procurement Notes

Verify RoHS compliance status as the specific part number may not meet current environmental standards. Confirm package dimensions against PCB footprint requirements. Check for lead-free alternatives if required by manufacturing regulations. Validate supplier authenticity through authorized channels due to end-of-life status.

Selection Notes

Select this component for applications requiring fast synchronous access with flow-through latency. Ensure system design accommodates the 3.3V I/O levels and power supply tolerances. Consider thermal management for the TQFP package in enclosed environments. Verify compatibility with existing bus architectures before integration.

Part Context

This device belongs to the IDT 71V3579 family of synchronous SRAMs designed for demanding embedded applications. It offers a balance of density and speed suitable for buffering and caching roles in digital systems. The product line emphasizes low power consumption and reliable operation across standard industrial temperature ranges.

Replacement Considerations

The 71V3579S65PFG is directly replaced by the 71V3579S65PFG from Renesas Electronics Corporation.
