71V65703S80BQI

Overview

The 71V65703S80BQI is a 9-Mbit synchronous static random-access memory (SRAM) device manufactured by Renesas Electronics Corporation. It features a parallel interface and is organized as 256K words by 36 bits. The component operates with a maximum clock frequency of 125 MHz and supports an access time of 8 nanoseconds. It functions within a supply voltage range of 3.135V to 3.465V and is designed for surface mount installation in a 165-pin CABGA package measuring 13mm by 15mm. The device supports an industrial 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, enhancing system throughput.
• Synchronous Single Data Rate (SDR) architecture utilizes address, data-in, and control signal registers for precise timing alignment.
• Flow-through output configuration provides direct data access without additional output registration latency.
• Burst mode capability allows the delivery of four cycles of data for a single presented address.

Applications

• High-performance embedded systems requiring fast data buffering
• Industrial equipment with real-time processing demands
• Network infrastructure components needing low-latency memory access

Procurement Notes

Verify current manufacturing status as the product line may be subject to end-of-life notices. Confirm package authenticity and moisture sensitivity level handling requirements before assembly. Ensure compatibility with existing board layouts regarding the 165-pin CABGA footprint and electrical specifications.

Selection Notes

Select this component when zero bus turnaround performance is critical for system efficiency. Consider the 36-bit word width for applications requiring wide data paths without external multiplexing. Evaluate thermal management needs for the specified industrial temperature range and power consumption characteristics.

Part Context

This SRAM belongs to the 71V65703 family, which includes variants with different access times and packaging options such as PBGA and TQFP. The family shares common ZBT architectural features but differs in speed grades and physical form factors to suit diverse design constraints.

Replacement Considerations

Potential substitutes include the 71V65703S85BQGI and 71V65703S80PFGI. Verify pinout compatibility and electrical parameter alignment before implementation.
