71V65603S100BQG

Overview

The 71V65603S100BQG is a synchronous static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics. It features a storage capacity of 9 Mbit, organized as 256K x 36 bits. The device operates with a maximum clock frequency of 100 MHz and supports parallel interface communication. It utilizes a 165-CABGA package with dimensions of 13x15 mm. The supply voltage range is specified from 3.135 V to 3.465 V. The component is designed for surface mount installation and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Supports Zero Bus Turnaround (ZBT) technology to eliminate dead bus cycles during read/write transitions.
• Includes address, data-in, and control signal registers for synchronous operation.
• Capable of providing four cycles of data in burst mode for a single address.

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded systems
• Data storage in industrial automation controllers

Procurement Notes

Verify the specific suffix BQG to confirm the 165-CABGA package type and commercial temperature range. Confirm RoHS compliance status as documentation may vary by production date. Check for End-of-Life notices or obsolescence warnings before finalizing procurement plans. Ensure moisture sensitivity level handling procedures are followed during assembly.

Selection Notes

Select this component when a 256K x 36 organization is required for wide-data applications. Choose based on the 100 MHz synchronous performance requirement. Verify that the 165-pin CABGA footprint matches the PCB design constraints. Ensure the 3.3V I/O logic levels are compatible with the host system.

Part Context

This part belongs to the 71V65603 series of ZBT synchronous SRAMs. It shares architectural similarities with other variants in the family but differs in speed grade and packaging. The series is designed for high-performance memory applications requiring fast turnaround times between bus directions.
