71V65803S100PFGI

Overview

The 71V65803S100PFGI is a synchronous single data rate zero bus turnaround SRAM manufactured by Renesas Electronics Corporation. It provides a total storage capacity of 9 megabits, organized as 512K words by 18 bits. The device operates with a maximum clock frequency of 100 MHz and features an access time of 5 nanoseconds. It utilizes a parallel interface and requires a supply voltage between 3.135V and 3.465V. The component is housed in a 100-pin TQFP package measuring 14x14 mm and supports surface mount installation.

Feature Summary

• Supports synchronous single data rate operation with zero bus turnaround capability for efficient data transfer.
• Provides high-speed memory access through a parallel interface architecture optimized for system performance.
• Designed for industrial temperature ranges to ensure reliable operation in demanding environments.

Applications

• High-performance embedded systems requiring fast random access memory
• Network infrastructure equipment needing low-latency data buffering
• Industrial control systems utilizing synchronous logic interfaces

Procurement Notes

Verify the specific suffix PFGI to confirm the 100-TQFP package type and lead-free compliance status. Confirm RoHS3 adherence if required by your manufacturing standards. Check current availability as this part may be subject to long lead times or limited stock due to its age. Ensure the operating voltage range matches your system's power delivery network before integration.

Selection Notes

Select this component when a 9Mb synchronous SRAM with a 100 MHz clock speed is required. The 5 ns access time suits applications needing rapid data retrieval. Consider the 100-pin TQFP footprint for PCB layout compatibility. Verify that the 3.3V nominal supply voltage aligns with your design constraints and that the parallel interface fits your controller's capabilities.

Part Context

This device belongs to the IDT 71V65803 family of synchronous SRAMs. It shares architectural similarities with other members like the 71V65803S133PFGI but offers a lower 100 MHz clock speed. The family is designed for high-density memory applications where synchronous timing is critical for system synchronization and data integrity.

Replacement Considerations

The 71V65803S133PFGI serves as a faster alternative within the same package and organization. For pin-compatible replacements, verify electrical specifications carefully. No direct obsolete substitutes are confirmed in the provided data; consult manufacturer resources for current lifecycle status.
