71V65703S85BQG

Overview

The IDT71V65703S85BQG is a 9Mb (256K x 36) synchronous ZBT SRAM manufactured by Renesas Electronics Corporation. It features a parallel interface with an access time of 8.5 ns and operates within a supply voltage range of 3.135V to 3.465V. The device utilizes a 165-CABGA package measuring 13x15 mm, supports surface mount installation, and functions across a temperature range of -40°C to 85°C.

Feature Summary

• Eliminates dead bus cycles during read-to-write or write-to-read transitions using Zero Bus Turnaround technology
• Contains internal registers for address, data-in, and control signals to synchronize operations
• Provides flow-through outputs without requiring external output data registers

Applications

• High-performance system memory buffering
• Data storage in network infrastructure equipment
• Embedded systems requiring fast random access

Procurement Notes

Verify component authenticity through authorized channels as the part is obsolete. Confirm RoHS3 compliance and MSL level 3 handling requirements. Check for specific assembly site variations via official PCN documents before integration into production lines.

Selection Notes

Select this component for applications requiring high-speed parallel data access with minimal turnaround latency. Ensure the design accommodates the 165-pin CABGA footprint and strict thermal management for the extended industrial temperature range.

Part Context

This device belongs to the 71V65703 family of 3.3V CMOS SRAMs. It shares architectural similarities with other ZBT SRAMs but is distinguished by its specific 256K x 36 organization and 165-ball BGA packaging configuration.

Replacement Considerations

Public confirmed substitutes include 71V65603S150BQGI and IS64LF25636A-7.5B3LA3-TR.
