71V65703S85BGI

Overview

The 71V65703S85BGI 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 supply voltage range of 3.135V to 3.465V and features an access time of 8.5 ns. It is housed in a 165-CABGA package measuring 13x15 mm, designed for surface mount installation.

Feature Summary

• Zero Bus Turnaround (ZBT) architecture eliminates dead bus cycles between read and write operations
• Contains registers for address, data-in, and control signals to optimize interface timing
• Flow-through output configuration provides data without additional output register latency
• Supports burst mode operation delivering four cycles of data for a single address

Applications

• High-speed parallel data buffering in telecommunications equipment
• Cache memory implementation in network processing systems
• Data storage in industrial control applications requiring fast turnaround times
• Embedded systems utilizing ZBT SRAM interfaces

Procurement Notes

Verify component authenticity through authorized channels as the part may be subject to obsolescence notices. Confirm package marking and date codes against current manufacturing records. Ensure compatibility with existing PCB footprints and signal integrity requirements before integration into new designs.

Selection Notes

Select this component when zero bus turnaround performance is required for 36-bit wide data paths. Compare against standard synchronous SRAMs if bus turnaround latency is not a critical constraint. Verify that the CABGA-165 package dimensions fit within the mechanical constraints of the target assembly.

Part Context

This device belongs to the 71V65703 family of ZBT synchronous SRAMs. It shares architectural similarities with other members of the series but differs in specific speed grades and packaging options. The 85 suffix indicates the 8.5 ns access time variant within this product line.
