71V65703S85PFGI8

Overview

The 71V65703S85PFGI8 is a synchronous Single Data Rate Zero Bus Transition SRAM manufactured by Renesas Electronics Corporation. It provides a storage capacity of 9 Megabits organized as 256K words by 36 bits. The device features a parallel interface with an access time of 8.5 nanoseconds and operates at a clock frequency of up to 117 MHz. It functions within a supply voltage range of 3.135V to 3.465V and supports an operating temperature range from -40°C to +85°C. The component is housed in a 100-pin Thin Quad Flat Package measuring 14x14 millimeters and utilizes tape and reel packaging.

Feature Summary

• Supports high-speed synchronous data transfer using Zero Bus Transition technology to minimize power consumption and signal noise.
• Provides wide 36-bit data organization suitable for applications requiring high bandwidth memory interfaces.
• Operates on a single 3.3V power supply with specified voltage tolerance ranges for stable performance.

Applications

• High-performance networking equipment requiring fast packet buffering
• Telecommunications infrastructure systems
• Industrial control systems with strict timing requirements

Procurement Notes

Verify the specific suffix PFGI8 to confirm the 100-TQFP package and tape-and-reel shipping format. Confirm RoHS3 compliance status as per current manufacturer documentation. Check for End-of-Life notices or alternative part recommendations from Renesas due to potential production phase-outs. Ensure design-in compatibility with existing PCB footprints for the 14x14mm QFP outline.

Selection Notes

Select this component when a 36-bit wide synchronous SRAM interface is required for system architecture. The 8.5 ns access time suits designs needing moderate to high speed data retrieval. Consider the 100-pin TQFP package constraints for board space and thermal management. Evaluate the -40°C to +85°C industrial temperature rating against environmental conditions.

Part Context

This part belongs to the 71V65703 family of synchronous ZBT SRAMs. It shares architectural similarities with other variants in the series but differs in package type and shipping configuration. The base model IDT71V65703 defines the core memory specifications, while the suffixes denote specific physical and logistical attributes defined by the manufacturer.

Replacement Considerations

Publicly confirmed substitute part numbers include 71V65703S85BQGI and 71V65703S85BG. Verify pinout compatibility and package dimensions before substitution. Other similar alternatives may exist but require separate validation against official datasheets.
