71V65903S80PFG

Overview

The IDT71V65903S80PFG is a 9Mb (512K x 18) Synchronous ZBT SRAM manufactured by Renesas Electronics. It operates with a supply voltage of 3.135V to 3.465V and features an access time of 8 ns. The device utilizes a parallel interface and is housed in a 100-TQFP (14x14) surface-mount package. It supports high-performance system speeds up to 100 MHz.

Feature Summary

• Zero Bus Transition (ZBT) technology eliminates dead cycles between write and read operations.
• Flow-through architecture provides synchronous output data without wait states.
• Single R/W control pin simplifies interface logic requirements.

Applications

• High-speed cache memory systems
• Network infrastructure equipment
• Industrial automation controllers

Procurement Notes

Verify the current lifecycle status, as this component may be obsolete or subject to production changes. Confirm RoHS compliance and moisture sensitivity levels against specific datasheet revisions before integration into new designs.

Selection Notes

Select this part for applications requiring low-latency burst transfers and simplified control logic. Ensure the design accommodates the 3.3V I/O requirements and the thermal characteristics of the TQFP-100 package within the specified operating temperature range.

Part Context

This component belongs to the 71V65903 family of 3.3V Synchronous ZBT SRAMs. It shares architectural similarities with other variants in the series, differing primarily in access speed and packaging options while maintaining consistent functional specifications.

Replacement Considerations
