71V321S25TF

Overview

The 71V321S25TF is a 16Kbit (2K x 8) asynchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It features a parallel interface with a maximum access time of 25 ns and operates within a supply voltage range of 3.0 V to 3.6 V. The device is housed in a 64-TQFP surface-mount package measuring 10x10 mm. It supports independent read/write operations on both ports simultaneously, making it suitable for high-speed data buffering applications.

Feature Summary

• Supports simultaneous independent read and write operations on two separate ports without bus contention.

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded systems
• Data storage in industrial control networks

Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm RoHS compliance requirements as the original part may not meet current environmental standards. Check for moisture sensitivity level handling during storage and assembly. Validate pin compatibility if substituting with newer variants from the same family.

Selection Notes

Select this component when dual-port functionality is required for concurrent data access. Ensure system voltage aligns with the 3.0 V to 3.6 V operating range. Consider the 25 ns access speed for timing constraints. Evaluate package size suitability for PCB layout. Verify end-of-life status impacts long-term production viability.

Part Context

This part belongs to the 71V321L/S series of asynchronous dual-port SRAMs. It shares architectural similarities with other members like the 71V321L25TF but differs in specific suffix designations indicating package or temperature variations. The series is designed for applications requiring non-blocking memory access between two masters.

Replacement Considerations

Official upgrade alternatives include the 71V321L25TFG. Verify pinout compatibility and electrical specifications before substitution. Note that replacement parts may have updated RoHS compliance status.
