71V65703S80PFG

Overview

The IDT71V65703S80PFG is a 9Mb synchronous static random-access memory (SRAM) organized as 256K x 36. It operates at a clock frequency of 100 MHz with an access time of 8 ns. The device uses a 3.3V power supply and features a parallel interface. It is housed in a 100-pin TQFP package measuring 14x14 mm.

Feature Summary

• Supports high-performance system speeds up to 100 MHz
• ZBT feature eliminates dead cycles between write and read operations
• Internally synchronized output buffer enable simplifies control

Applications

• High-speed data buffering in communication systems
• Cache memory for network processors
• Storage for digital signal processing applications

Procurement Notes

Verify the specific suffix PFG confirms the 100-TQFP package and commercial temperature range. Confirm RoHS compliance status as manufacturing sources may vary. Check for obsolescence notices from Renesas Electronics, which acquired IDT. Ensure the source document explicitly lists this part number to avoid confusion with similar ZBT SRAM variants.

Selection Notes

Select this component when a 256K x 36 organization is required for wide-data interfaces. The 8 ns access time suits systems needing 100 MHz synchronous operation. Consider the TQFP-100 package for surface-mount assembly constraints. Verify that the 3.3V I/O logic levels match the host processor requirements.

Part Context

This part belongs to the IDT 71V65703 family of 3.3V Synchronous ZBT SRAMs. These devices are designed for high-throughput applications requiring low latency. The family typically includes variations in speed grades and package types, such as BGA options, while maintaining the same core architecture and pinout compatibility.

Replacement Considerations

Public confirmed substitute part numbers include 71V65703S85PFGI8 and 71V65703S80PFGI8. Verify package type and temperature range compatibility before substitution.
