71V65703S85BGI8

Overview

The 71V65703S85BGI8 is a synchronous static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 9 megabits, organized as 256K words by 36 bits. The device utilizes a parallel interface with an access time of 8.5 nanoseconds and operates on a single 3.3-volt power supply within the range of 3.135 to 3.465 volts. It is housed in a 165-pin CABGA package measuring 13x15 millimeters and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Zero Bus Turnaround (ZBT) technology eliminates dead bus cycles during read-to-write or write-to-read transitions.
• Includes registers for address, data-in, and control signals to optimize data throughput.
• Flow-through output architecture provides direct data access without additional output registers.

Applications

• High-speed digital signal processing systems
• Network infrastructure equipment requiring low-latency buffering
• Industrial control systems demanding wide data word widths

Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status as specific suffixes may vary. Check for End-of-Life notices or Product Change Notifications regarding substrate or labeling updates. Ensure thermal management aligns with the specified industrial temperature range during installation.

Selection Notes

Select this component when a 36-bit data width is required for system compatibility. The ZBT feature is essential for applications needing minimal turnaround latency between bus directions. Verify that the PCB layout supports the 165-pin CABGA footprint dimensions. Ensure the design accommodates the 3.3V I/O voltage levels for proper interfacing.

Part Context

This part belongs to the 71V65703 family of high-performance synchronous SRAMs. It shares architectural similarities with other ZBT devices but is distinguished by its specific 256K x 36 organization and 8.5 ns speed grade. The CABGA package variant offers enhanced thermal performance compared to standard BGA options.
