71V65703S75BQ

Overview

The IDT71V65703S75BQ 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 parallel interface and requires a supply voltage between 3.135V and 3.465V. It supports a working temperature range from -40°C to 85°C. The component is housed in a 165-CABGA package.

Feature Summary

• Zero bus turnaround architecture eliminates dead cycles during read-to-write or write-to-read transitions.
• Internally synchronized output buffer enable removes the need for external OE control.
• Flow-through output architecture provides direct data access without additional registers.

Applications

• High-performance embedded systems requiring fast memory turnaround
• Network infrastructure equipment
• Industrial automation controllers

Procurement Notes

Verify the specific suffix BQ corresponds to the CABGA-165 package configuration. Confirm RoHS compliance status as documentation varies by revision. Ensure the operating voltage range matches the target system design constraints before integration.

Selection Notes

Select this component when zero bus turnaround performance is critical for system throughput. The synchronous SDR interface simplifies timing compared to asynchronous alternatives. Verify that the 165-pin CABGA footprint fits the PCB layout requirements.

Part Context

This part belongs to the 71V65703/903 family of 3.3V synchronous ZBT SRAMs. It shares architectural features with other members like the 71V65703S85PFGI8 but differs in speed grade and package type. The ZBT technology distinguishes it from standard synchronous SRAMs by removing bus turnaround latency.

Replacement Considerations

IDT71V65703S85BQI8 offers similar functionality with an 8.5 ns access time. IS61LF25636A-7.5TQLI is a potential alternative from ISSI with comparable speed specifications.
