71V321L25J8

Overview

The Renesas 71V321L25J8 is a dual-port static random-access memory (SRAM) device organized as 2K x 8 bits, providing a total storage capacity of 16 kilobits. It operates on a single 3.3V power supply with a voltage range of 3.0V to 3.6V. The component features an asynchronous parallel interface with a maximum access time of 25 nanoseconds. It is housed in a 52-lead Plastic Leadless Chip Carrier (PLCC) package and supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Dual-port architecture enabling independent read/write operations for two masters
• Asynchronous parallel interface requiring no clock signals
• Low power consumption characteristics suitable for battery-operated systems

Applications

• High-speed data buffering in communication equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial control applications

Procurement Notes

Verify the specific suffix J8 against official datasheets to confirm the PLCC-52 package and industrial temperature rating. Confirm RoHS compliance status as older variants may differ. Check for End-of-Life notices or obsolescence warnings before procurement planning.

Selection Notes

Select this component when a non-volatile-free, high-speed dual-port memory solution is required for 3.3V logic systems. Ensure the design accommodates the PLCC-52 footprint and that the 25ns access time meets the system timing requirements. Verify compatibility with existing bus architectures.

Part Context

This part belongs to the Renesas 71V321L series of asynchronous dual-port SRAMs. The series provides flexible memory solutions for applications requiring simultaneous access from multiple processors or controllers without complex arbitration logic.

Replacement Considerations

Consult official substitution guides for equivalent dual-port SRAMs with matching 16Kb capacity, 25ns speed, and PLCC-52 packaging. Verify pinout compatibility and electrical specifications before replacement.
