71V321S25PFI8

Memory IC Overview

The Renesas Electronics Corporation 71V321S25PFI8 is a dual-port static random access memory (SRAM) integrated circuit. It features a storage capacity of 16 kilobits, organized as 2K words by 8 bits. The device utilizes an asynchronous parallel interface with a maximum access time and write cycle time of 25 nanoseconds. It operates within a supply voltage range of 3 volts to 3.6 volts. The component is housed in a 64-lead Thin Quad Flat Package (TQFP) measuring 14x14 millimeters. It supports surface mount installation and functions across a temperature range of 0°C to 70°C.

Memory IC Feature Summary

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

Memory IC Applications

Data buffering in high-speed digital signal processing systems.

Memory IC Procurement Notes

This component is officially obsolete and no longer manufactured by Renesas Electronics Corporation. Verification of availability requires checking authorized distributors for remaining stock or approved upgrade alternatives. Confirm that the replacement part matches the required pinout, electrical specifications, and package dimensions to ensure compatibility with existing designs.

Memory IC Selection Notes

Designers should evaluate the 71V321L series as the designated upgrade path for this discontinued model. Verify that the alternative meets all original timing requirements and voltage constraints. Ensure the new component's packaging and thermal characteristics align with the current board layout and environmental operating conditions.

Memory IC Part Context

The 71V321S25PFI8 belongs to the Renesas 71V321S family of asynchronous dual-port SRAMs. This series provides non-volatile data retention during power loss but requires continuous power for operation. The specific suffix indicates the package type and speed grade within the broader product line.
