71V65603S150BQGI

Overview

The 71V65603S150BQGI is a 9-Mbit synchronous static random-access memory (SRAM) device manufactured by Renesas Electronics Corporation. It features a parallel interface with a memory organization of 256K x 36 bits. The component operates at a maximum clock frequency of 150 MHz with a typical access time of 3.8 ns. It requires a supply voltage range of 3.135V to 3.465V and is housed in a 165-CABGA package measuring 13x15 mm. The device supports surface mount installation and is designed for high-speed data storage applications.

Feature Summary

• Zero bus turnaround (ZBT) technology eliminates dead bus cycles during read-to-write or write-to-read transitions.
• Flow-through output architecture provides immediate data availability without additional output registers.
• Burst mode capability allows four cycles of data retrieval for a single address presentation.

Applications

• High-performance networking equipment requiring fast packet buffering
• Industrial control systems needing rapid data acquisition
• Telecommunications infrastructure for signal processing

Procurement Notes

Verify the specific suffix BQGI against official Renesas documentation to confirm package dimensions and pinout compatibility. Confirm RoHS compliance status as manufacturing processes may vary. Check for End-of-Life notices, as this component family has faced discontinuation events. Ensure thermal management solutions align with the CABGA package specifications for reliable operation.

Selection Notes

Select this part when a 36-bit wide data path is required for system bus integration. Compare access times and power consumption against alternative ZBT SRAMs if lower latency is critical. Verify that the 165-ball BGA footprint fits within the target PCB design constraints. Consider temperature ratings if the application environment exceeds standard commercial limits.

Part Context

This component belongs to the 71V65603 series of synchronous SRAMs, which are engineered for high-speed parallel data transfer. The series utilizes CMOS technology to provide low power consumption while maintaining high performance. It is commonly used in embedded systems where deterministic timing and high bandwidth are essential for real-time operations.
