71V321L25J

Overview

The Renesas Electronics 71V321L25J is a static random-access memory component featuring a 16 kbit storage capacity organized as 2K x 8. It operates on a 3.3V dual-port architecture with asynchronous parallel interface and a 25 ns access time. The device supports a supply voltage range of 3 V to 3.6 V, with maximum power consumption up to 130 mA. It is housed in a 52-PLCC package suitable for surface mount installation.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations
• Asynchronous parallel interface for flexible system integration
• Single data rate operation supporting standard memory protocols

Applications

• High-speed data buffering in embedded systems
• Cache memory implementation in microcontroller designs
• Real-time data logging applications requiring fast access

Procurement Notes

Verify current availability status as this component may be subject to end-of-life notices or limited distribution channels. Confirm RoHS compliance requirements against specific project standards, as older variants may not meet current environmental regulations. Validate package integrity upon receipt due to potential moisture sensitivity handling requirements during storage and shipping processes.

Selection Notes

Select this part when dual-port functionality is required for concurrent processor access without arbitration overhead. Ensure the 52-PLCC package fits the target PCB footprint constraints. Verify that the 3.3V operating voltage aligns with the system logic levels and that the 25 ns speed meets the timing requirements of the host controller interface design specifications.

Part Context

This component belongs to the 71V321 series of dual-port SRAMs from Renesas Electronics. The series offers various speed grades and packaging options to accommodate different performance and form factor needs in industrial and commercial electronic applications. The L25 suffix typically denotes the 25 nanosecond access time variant within this product family lineage.

Replacement Considerations

Check for direct pin-compatible substitutes such as the IDT71V321L25J if available through authorized distributors. Verify electrical parameter equivalence including voltage ranges and access times before substitution. Consider newer generation parts from the same manufacturer if long-term supply assurance is critical for production continuity.
