71V65903S85BQG8

Overview

The Renesas 71V65903S85BQG8 is a 9Mbit (512K x 18) Synchronous SRAM utilizing Zero Bus Turnaround (ZBT) technology. It features an 8.5 ns access time and operates on a single 3.3V power supply within the 3.135V to 3.465V range. The device is housed in a 165-CABGA package with dimensions of 13x15 mm, designed for surface mount installation.

Feature Summary

• Supports high-speed parallel data transfer via synchronous interface architecture
• Utilizes Zero Bus Turnaround technology to minimize bus turnaround latency
• Operates on a standard 3.3V single power supply voltage

Applications

• High-performance embedded systems requiring fast memory access
• Network infrastructure equipment
• Industrial control applications

Procurement Notes

Verify component authenticity through authorized channels due to End-of-Life status. Confirm RoHS compliance and moisture sensitivity level prior to assembly. Check for specific suffix variations that may indicate different temperature ranges or packaging types. Ensure supply chain stability as discontinuation schedules may affect long-term availability.

Selection Notes

Select this component for designs requiring 9Mb capacity with 18-bit word width. The 165-CABGA package suits high-density board layouts. Consider the 8.5 ns speed grade against system clock requirements. Evaluate thermal performance within the specified operating temperature range during PCB design.
