71V321L55JI

Overview

The Renesas Electronics Corporation 71V321L55JI is a dual-port static random access memory (SRAM) integrated circuit. It features a storage capacity of 16 kbit organized as 2K x 8 bits. The device supports parallel interface communication with an access time of 55 ns. It operates within a supply voltage range of 3 V to 3.6 V and functions at temperatures between -40°C and +85°C. The component is housed in a 52-PLCC package.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous operation for flexible system integration without clock synchronization requirements
• Parallel data interface supporting standard digital logic connections

Applications

• High-speed data buffering in embedded systems
• Cache memory implementation in microprocessor designs
• Data storage in industrial control applications

Procurement Notes

Verify the specific suffix 'JI' against official Renesas documentation to confirm package type and temperature grade. Confirm RoHS compliance status as older variants may not meet current environmental standards. Check for active production status or end-of-life notifications before procurement planning.

Selection Notes

Select this component when dual-port functionality is required for concurrent data access. Ensure the 3.3V operating voltage aligns with the target system power rails. Verify that the 55 ns access speed meets the timing constraints of the application. Consider the PLCC package footprint during PCB layout design.

Part Context

This part belongs to the 71V321L series of dual-port SRAMs from Renesas Electronics. The series offers various speed grades and packaging options to suit different performance and form factor requirements in electronic circuits.

Replacement Considerations
