71V321S25J8

Overview

The Renesas Electronics Corporation 71V321S25J8 is a static random-access memory (SRAM) device belonging to the 71V321 series. It features a storage capacity of 16 kbit organized as 2K x 8 bits. The component operates with an asynchronous parallel interface and supports a supply voltage range from 3 V to 3.6 V. It provides a maximum access time of 25 ns and has a maximum power supply current of 130 mA. The device is designed for surface mount installation in a 52-PLCC package. It functions within a commercial operating temperature range of 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 systems.

Procurement Notes

Verify component authenticity through authorized channels, as this part number is obsolete. Confirm that the specific suffix J8 corresponds to the 52-PLCC package variant. Check for RoHS compliance status, as older revisions may not meet current environmental standards. Ensure compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component only if legacy support for the 52-PLCC package is required. Verify that the 25 ns access speed meets system timing requirements. Consider the limited availability due to obsolescence when planning long-term production. Evaluate alternative packages if design flexibility allows.

Part Context

This SRAM belongs to the Renesas 71V321 family of dual-port memories. The 'S' designation typically indicates the commercial temperature grade and PLCC packaging. The '25' denotes the 25 ns access speed. The 'J8' suffix specifies the lead-free or specific tape/reel variation within the PLCC form factor, though standard documentation often lists the base 71V321S25J.

Replacement Considerations

The 71V321L25JG is listed as an upgrade replacement. Verify pinout compatibility and electrical specifications before substitution.
