71V65603S150PFG

Overview

The 71V65603S150PFG is a 9 Mbit Synchronous Single Data Rate (SDR) Zero Bus Turnaround (ZBT) Static Random Access Memory (SRAM) manufactured by Renesas Electronics Corporation. It features a parallel interface with a memory organization of 256K x 36 bits. The device supports a maximum clock frequency of 100 MHz and offers an access time of 10 ns. It operates within a supply voltage range of 3.135 V to 3.465 V and is housed in a 100-TQFP surface-mount package.

Feature Summary

• Supports synchronous single data rate operations with zero bus turnaround technology to eliminate dead cycles during read-write transitions.
• Provides high-speed parallel data transfer capabilities suitable for demanding system architectures.
• Designed for reliable performance across industrial temperature ranges.

Applications

• High-performance embedded systems requiring fast random access memory
• Network infrastructure equipment and telecommunications hardware
• Industrial control systems and automation controllers

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific lot codes against current regulatory requirements before integration. Ensure proper handling procedures are followed given the surface-mount packaging type and moisture sensitivity level specifications outlined in the datasheet.

Selection Notes

Select this component when a 9 Mbit capacity with a 36-bit wide data bus is required for synchronous applications. The 100 MHz operation speed and 10 ns access time make it suitable for systems needing moderate-to-high bandwidth. Consider the 100-TQFP package dimensions for PCB layout compatibility and verify that the 3.3 V operating voltage aligns with the target system's power supply architecture.

Part Context

This part belongs to the 71V65603 series of ZBT SRAMs, which are designed to replace asynchronous SRAMs in high-speed designs without requiring wait states. The series offers various speed grades and package options to accommodate different system timing and physical space constraints while maintaining pin-to-pin compatibility within the family.

Replacement Considerations

Check for end-of-life notifications as this specific variant may be discontinued. Evaluate alternative speed grades such as the 71V65603S133PFGI or 71V65603S100PFGI for functional equivalence. Verify pinout compatibility and electrical characteristics before substituting with other manufacturers' parts like ISSI equivalents.
