71V65703S80BQGI8

Overview

The 71V65703S80BQGI8 is a 9Mb (256K x 36) synchronous static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It utilizes Zero Bus Turnaround (ZBT) technology to eliminate dead bus cycles during read/write transitions. The device operates with a clock frequency of 100 MHz and features an access time of 8 ns. It supports a supply voltage range of 3.135V to 3.465V and is housed in a 165-CABGA package measuring 13x15 mm. The component is designed for surface mount installation and functions within an industrial temperature range of -40°C to 85°C.

Feature Summary

• Zero Bus Turnaround (ZBT) technology eliminates dead bus cycles between read and write operations.
• Contains registers for address, data-in, and control signals to synchronize input data.
• Flow-through output architecture provides data without additional output registration latency.
• Supports burst mode operation to deliver four cycles of data for a single address.

Applications

• High-speed digital signal processing systems requiring low-latency memory access
• Network infrastructure equipment utilizing parallel SRAM interfaces
• Industrial control systems operating within extended temperature ranges
• Embedded applications needing fast turnaround between read and write cycles

Procurement Notes

Verify the specific suffix BQGI8 against official Renesas documentation to confirm package dimensions and pinout compatibility. Confirm RoHS3 compliance status as manufacturing sites may vary. Check for End-of-Life notifications or Product Change Notices affecting availability. Ensure design-in approval for the 165-CABGA footprint prior to procurement.

Selection Notes

Select this component when ZBT performance is required to maximize bus efficiency in parallel memory architectures. The 256K x 36 organization suits wide-data-path applications. Verify that the 165-CABGA package fits the target PCB constraints. Ensure the system power supply maintains the 3.135V to 3.465V range for stable operation.

Part Context

This part belongs to the 71V65703 family of synchronous SRAMs from Renesas. The family shares core ZBT functionality but varies in speed grades, package types, and temperature ratings. The 71V65703 series is designed to replace asynchronous SRAMs in high-performance designs while maintaining pin compatibility with standard parallel interfaces.
