71V65803S100PFGI

Overview

The IDT71V65803S100PFGI is a 9Mb Synchronous ZBT SRAM organized as 256K x 36. It operates at a clock frequency of 100 MHz with a 5 ns access time. The device uses a 3.3V core supply and features a 100-pin TQFP package measuring 14x20 mm. It supports parallel interface operations within an industrial temperature range of -40°C to 85°C.

Feature Summary

• Supports high-speed synchronous operation via Zero Bus Turnaround (ZBT) technology for efficient data transfer.
• Features pipelined architecture to allow overlapping read and write cycles without dead cycles.
• Includes internal burst address counter supporting linear or interleaved burst modes.

Applications

• High-performance computing systems requiring fast memory access
• Network infrastructure equipment
• Industrial control systems

Procurement Notes

Verify the component status, as this specific part number may be discontinued or subject to product change notifications. Confirm that the 100-TQFP package dimensions and pinout match the design requirements. Ensure compliance with RoHS3 specifications if required by the target application environment.

Selection Notes

Select this component when a 256K x 36 organization is required for synchronous memory applications. It is suitable for designs needing 100 MHz performance with low latency. Consider the 100-pin TQFP footprint for PCB layout constraints and verify thermal management capabilities for the specified operating temperature range.

Part Context

This device belongs to the IDT 71V65803 family of 3.3V Synchronous ZBT SRAMs. It shares architectural similarities with other members like the 71V65603 but differs in memory organization width. The family is characterized by its ability to eliminate bus turnaround delays, enhancing system throughput compared to traditional synchronous SRAMs.

Replacement Considerations

Public confirmed substitute part numbers include 71V65703S80PFGI and 71V65803S133PFGI from Renesas Electronics Corporation.
