71V65603S150BQGI8

Overview

The 71V65603S150BQGI8 is a synchronous Single Data Rate Zero Bus Turnover SRAM manufactured by Renesas Electronics Corporation. It features a storage capacity of 9 Megabits, organized as 256K words by 36 bits. The device supports a maximum clock frequency of 150 MHz with an access time of 3.8 nanoseconds. It operates on a single 3.3V power supply within the range of 3.135V to 3.465V. The component is housed in a 165-pin CABGA package measuring 13x15 mm and is designed for surface mount installation.

Feature Summary

• Supports high-speed parallel data transfer via synchronous interface architecture
• Eliminates bus turnaround latency through Zero Bus Turnover technology
• Operates on a standard 3.3V single power supply rail
• Provides reliable data retention within specified commercial temperature ranges

Applications

• High-performance networking equipment buffer memory
• Telecommunications system signal processing caches
• Industrial control system data logging storage
• Embedded computing applications requiring fast random access

Procurement Notes

Verify the specific suffix BQGI8 against official Renesas documentation to confirm pinout compatibility and moisture sensitivity level requirements. Ensure the ordering information matches the exact package dimensions and lead finish specifications required for the target PCB assembly process. Confirm RoHS compliance status for the specific manufacturing batch before integration into final products.

Selection Notes

Select this component when a 36-bit wide data path is required for system architecture compatibility. The 150 MHz speed grade offers a balance between performance and power consumption for mid-range embedded applications. Consider the 165-pin CABGA package constraints regarding board space and thermal dissipation capabilities during the initial hardware design phase.

Part Context

This part belongs to the 71V65603 series of synchronous ZBT SRAMs from Renesas. The series provides various speed grades and package options to suit different system timing requirements. The 71V65603 family is widely used in applications demanding low-latency memory access without the complexity of dynamic refresh cycles associated with DRAM technologies.

Replacement Considerations

Direct replacements include the 71V65603S150BQ or 71V65603S150BQGI. Verify that substitute parts maintain identical pin configurations and electrical characteristics to ensure seamless integration without redesigning the host circuit board.
