71V321L35PF8

Overview

The Renesas Electronics Corporation 71V321L35PF8 is a static random-access memory (SRAM) integrated circuit featuring dual-port, asynchronous technology. It provides a storage capacity of 16 kilobits organized as 2K words by 8 bits. The device supports parallel interface operations with an access time and write cycle time of 35 nanoseconds. It operates within a supply voltage range of 3 volts to 3.6 volts and is housed in a 64-pin Thin Quad Flat Package (TQFP) measuring 14x14 millimeters. The component is rated for industrial operating temperatures from 0°C to 70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports.

Applications

• Data buffering in high-speed digital signal processing systems
• Cache memory implementation in embedded controllers
• FIFO buffer applications in communication interfaces

Procurement Notes

This specific part number is officially obsolete and no longer manufactured by Renesas Electronics Corporation. Verification of current availability requires checking authorized distributors for remaining stock or identifying approved replacement components. Procurement should prioritize verified substitute parts to ensure long-term supply chain stability and compliance with project lifecycle requirements.

Selection Notes

Designers requiring this memory configuration must evaluate the available upgrade path, specifically the 71V321L25PFG8 series. Selection criteria should focus on verifying pin compatibility, electrical parameter alignment, and package dimensions between the obsolete 71V321L35PF8 and its designated successor to ensure seamless integration without board redesign.

Part Context

The 71V321L35PF8 belongs to the broader 71V321L family of dual-port SRAMs produced by Renesas Electronics. This family is characterized by asynchronous operation and parallel interfaces designed for versatile memory management tasks. The specific suffix indicates the 35ns speed grade and the TQFP-64 packaging variant within this product line.

Replacement Considerations

The official upgrade replacement for the 71V321L35PF8 is the 71V321L25PFG8. Engineers should verify that the faster 25ns access time of the replacement does not require signal integrity adjustments in the existing design.
