71V3579S85PF

Overview

The IDT71V3579S85PF is a synchronous SDR SRAM IC with a 4.5Mb capacity organized as 256K x 18 bits. It features a parallel interface and an access time of 8.5 ns. The device operates within a supply voltage range of 3.135V to 3.465V and supports surface mount installation in a 100-TQFP (14x14) package.

Feature Summary

• Supports synchronous single data rate memory operations via a parallel interface.
• Provides fast 8.5 ns access times for high-speed data retrieval.

Applications

• High-performance embedded systems requiring rapid data access
• Network infrastructure equipment utilizing parallel memory interfaces
• Industrial control applications needing reliable volatile storage

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package dimensions against PCB footprint specifications before integration into final assembly designs.

Selection Notes

Select this component when a 256K x 18 organization is required with synchronous timing. Ensure system voltage aligns with the 3.135V to 3.465V operating range. Consider the 100-TQFP package constraints for thermal management and board space allocation during design phase.

Part Context

This part belongs to the IDT 71V3579 family of synchronous SRAM devices. It shares architectural similarities with other variants in the series, differing primarily in speed grades and packaging options. The manufacturer has transitioned ownership from IDT to Renesas Electronics Corporation.
