71V3578S150PFGI

Overview

The IDT71V3578S150PFGI is a 4.5Mb (256K x 18) Synchronous ZBT SRAM manufactured by Renesas Electronics Corporation, formerly IDT. It operates at a clock frequency of 150 MHz with a 3.8 ns access time. The device supports a supply voltage range of 3.135V to 3.465V and functions within an industrial temperature range of -40°C to 85°C. It utilizes a 100-pin TQFP package.

Feature Summary

• Supports high-speed system operations with 150 MHz clock frequency
• Features self-timed write cycles with global write control
• Includes burst counter for single-cycle deselect capability

Applications

• High-performance cache memory systems
• Industrial embedded processing applications
• Network infrastructure equipment

Procurement Notes

Verify component authenticity through authorized distributors as the part may be discontinued. Confirm RoHS compliance status and check for specific manufacturing date codes. Ensure the 100-TQFP package matches PCB footprint requirements before procurement.

Selection Notes

Select this component for designs requiring 256K x 18 organization with synchronous interface. Compare against alternative speed grades if lower latency is not critical. Verify thermal management capabilities for the specified industrial temperature range.

Part Context

This part belongs to the IDT71V3576/78 family of 3.3V Synchronous SRAMs. It shares architectural similarities with other members like the 71V3576YSA150PFG but differs in data width configuration. The series is designed for high-throughput parallel data transfer.
