71V65703S75PFI

Overview

The IDT71V65703S75PFI is a 9Mb (256K x 36) synchronous ZBT SRAM manufactured by Renesas Electronics. It operates at a clock frequency of 117 MHz with a 7.5 ns access time. The device uses a 100-TQFP package and supports a supply voltage range of 3.135V to 3.465V. It functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Zero Bus Turnaround (ZBT) technology eliminates dead cycles between read and write operations.
• Flow-through architecture provides immediate data output without internal output registers.
• Internal burst address counter supports four-word interleaved or linear burst modes.

Applications

• High-speed cache memory systems
• Network routing equipment buffers
• Industrial control system data storage

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance requirements as original specifications may vary from current available stock. Validate package integrity and moisture sensitivity level handling procedures before assembly.

Selection Notes

Select this component for applications requiring high throughput without bus turnaround latency. Ensure the design accommodates the specific 3.3V core and I/O voltage requirements. Verify that the 100-pin TQFP footprint matches the target PCB layout constraints.

Part Context

This part belongs to the IDT71V65703/903 family of 3.3V Synchronous ZBT SRAMs. It shares architectural similarities with other members like the IDT71V65703S85PFGI8 but offers faster 7.5 ns performance compared to slower variants in the same series.

Replacement Considerations

Public confirmed substitute part numbers include IS61LF25636A-7.5TQLI and ISSI alternatives such as IS61LPS25636A-200TQ2LI. Verify pin compatibility and electrical parameters before substitution.
