71V3579YS85PFG

Overview

The IDT 71V3579YS85PFG is a high-performance Synchronous Single Data Rate (SDR) Static Random-Access Memory (SRAM) integrated circuit manufactured by Integrated Device Technology Inc. This component provides a total memory capacity of 4.5 Mbit, organized as 256K words by 18 bits. It features an access time of 8.5 ns and utilizes a parallel interface for data transfer. The device is housed in a 100-TQFP package with dimensions of 14x14 mm.

Feature Summary

• Synchronous Single Data Rate architecture for precise clock-based data handling
• High-speed parallel interface supporting rapid data throughput
• Integrated Dual-Port memory cell technology for efficient data management

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• Digital signal processing applications requiring low latency

Procurement Notes

Verify the manufacturer origin, as Renesas Electronics Corporation acquired IDT's memory business. Confirm RoHS compliance status, as older batches may differ from current production runs. Ensure the specific suffix matches the required package and speed grade. Check for product discontinuance notices or last-buy deadlines associated with legacy inventory.

Selection Notes

Select this component when synchronous SRAM performance is required over asynchronous alternatives. The 18-bit width suits error-correction code implementations. Compare against the 71V3579S65PF for faster access times if system timing permits. Ensure voltage levels and interface compatibility with the host controller before integration.

Part Context

This part belongs to the IDT 71V3579 family of high-speed synchronous SRAMs. These devices are designed for demanding applications requiring fast random access. The family typically includes variants with different access speeds and packaging options to suit various board space and performance constraints.

Replacement Considerations

The 71V3579S65PFG is a documented direct replacement offering faster 6.5 ns access time within the same package.
