71V65603S100BQI

Overview

The Renesas Electronics Corporation 71V65603S100BQI is a synchronous single data rate (SDR) zero bus turnaround (ZBT) static random-access memory (SRAM) integrated circuit. It provides a total storage capacity of 9 Mbit, organized as 256K words by 36 bits. The device supports a maximum clock frequency of 100 MHz with a typical access time of 5 ns. It operates within a supply voltage range of 3.135 V to 3.465 V and features a parallel interface. The component is housed in a 165-pin CABGA package measuring 13x15 mm and is rated for an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Supports high-speed synchronous operation with a 100 MHz clock frequency and 5 ns access time.
• Features a wide 36-bit data width suitable for error correction code (ECC) applications.
• Utilizes zero bus turnaround (ZBT) technology to maximize throughput efficiency.
• Operates on a standard 3.3 V power supply with specified voltage tolerances.

Applications

• High-performance computing systems requiring fast data buffering
• Network infrastructure equipment utilizing ECC memory architectures
• Industrial control systems demanding reliable synchronous memory solutions

Procurement Notes

Verify the specific suffix BQI to confirm the 165-CABGA package and industrial temperature rating. Confirm RoHS compliance status as documentation may vary by production batch. Check for end-of-life notices or obsolescence announcements from Renesas Electronics prior to finalizing procurement plans. Ensure compatibility with existing PCB footprints designed for the 13x15 mm cavity ball grid array format.

Selection Notes

Select this component when a 36-bit data path is required for system-level error correction. Compare against other members of the 71V65603 series if different access speeds or package types are needed. Ensure the design accommodates the moisture sensitivity level and reflow soldering profiles specific to the CABGA package type.
