71V65803S100PFI

Overview

The IDT71V65803S100PFI is a 9Mb (512K x 18) synchronous ZBT SRAM manufactured by Renesas Electronics Corporation. It operates at a clock frequency of 100 MHz with a 5 ns access time, supporting parallel interface communication. The device utilizes a 3.3V core supply and features a 100-pin TQFP package measuring 14x14 mm. Designed for high-performance applications, it eliminates dead bus cycles between read and write operations through Zero Bus Turnaround technology.

Feature Summary

• Zero Bus Turnaround architecture eliminates dead cycles between read and write transitions
• Internally synchronized output buffer enable removes the need for external OE control
• Single R/W control pin simplifies interface logic and system design
• Supports four-word burst capability in interleaved or linear modes

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in network routers and switches
• Data storage in industrial automation control systems
• Memory modules for embedded computing platforms

Procurement Notes

Verify component authenticity as this part is discontinued. Confirm RoHS compliance status against specific manufacturing dates due to potential variations. Check for moisture sensitivity level handling requirements during storage and assembly. Ensure voltage levels match system specifications before integration.

Selection Notes

Select this component for designs requiring fast turnaround between read and write operations without bus contention. Consider the 100-pin TQFP package for surface mount compatibility. Evaluate thermal performance within the specified operating temperature range. Verify that the 3.3V core and I/O supplies align with existing power rails.

Part Context

This device belongs to the IDT 71V65803 family of synchronous ZBT SRAMs. It shares architectural similarities with other members like the IDT71V65903 series but differs in speed grades and packaging options. The family is designed for applications demanding high bandwidth and low latency memory solutions.

Replacement Considerations

Consider the IDT71V65803S133BQI as a verified substitute offering similar functionality with different speed characteristics. Verify pinout compatibility and electrical parameters before substitution.
