71V65703S85BQGI8

Overview

The 71V65703S85BQGI8 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 3.3V power supply within the range of 3.135V to 3.465V. It is housed in a 100-lead Thin Quad Flat Pack (TQFP) package measuring 14x14 mm. The component supports an operating temperature range from -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Implements Zero Bus Turnaround (ZBT) technology to eliminate dead bus cycles during read-write transitions.
• Includes registers for address, data-in, and control signals to optimize data throughput.
• Provides flow-through outputs without additional output data registers for direct access.

Applications

• High-performance embedded systems requiring fast data access
• Network infrastructure equipment
• Industrial automation controllers

Procurement Notes

Verify the suffix 'I8' corresponds to the tape-and-reel packaging format, distinct from tray-packaged variants like BQGI. Confirm the specific pinout and electrical characteristics against the official datasheet, as suffixes may indicate variations in moisture sensitivity or assembly location. Ensure compatibility with existing PCB footprints for the 100-TQFP package before integration.

Selection Notes

Select this component when a 9Mb synchronous SRAM with ZBT functionality is required in a compact TQFP package. It is suitable for designs needing 8.5ns access times and 3.3V operation. Compare with other suffixes such as BQGI for BGA packages if space constraints differ. Verify that the industrial temperature range meets environmental requirements.

Part Context

This part belongs to the 71V65703 family of ZBT synchronous SRAMs. It shares core architectural features with variants like 71V65703S85BQGI but differs in packaging and reel configuration. The family is designed for applications demanding high-speed data buffering and low-latency memory access in complex digital systems.

Replacement Considerations

Direct substitutes include 71V65703S85BQGI for tray packaging or 71V65703S85PFGI for alternative QFP options. Cross-vendor equivalents require careful verification of pinouts and timing parameters.
