71V321L35JGI

Overview

The Renesas Electronics Corporation 71V321L35JGI is a static random-access memory (SRAM) integrated circuit belonging to the 71V321L series. It features a storage capacity of 16 kilobits organized as 2K by 8 bits. The device utilizes an asynchronous parallel interface with a maximum access time of 35 nanoseconds. It operates within a supply voltage range of 3 volts to 3.6 volts and has a maximum power supply current of 130 milliamperes. The component supports an industrial operating temperature range from -40 degrees Celsius to +85 degrees Celsius and is housed in a 52-lead Plastic Leadless Chip Carrier (PLCC) package.

Feature Summary

• Dual-port architecture enabling independent simultaneous read and write operations
• Asynchronous operation for flexible system integration without clock synchronization requirements
• Parallel interface supporting standard data bus widths

Applications

• Data buffering in high-speed digital systems
• Cache memory implementation in embedded controllers
• Temporary storage in telecommunications equipment

Procurement Notes

Verify the specific suffix JGI confirms the 52-PLCC package and industrial temperature grade (-40°C to +85°C). Confirm RoHS3 compliance status through official documentation. Check for End-of-Life notifications or Product Change Notices affecting availability. Ensure compatibility with existing PCB footprints for 52-PLCC components during sourcing.

Selection Notes

Select this component when dual-port functionality is required for concurrent master-slave memory access. The 35 ns speed suits moderate-frequency asynchronous applications. Verify that the 52-PLCC surface-mount package fits the design constraints. Consider the 3V to 3.6V supply requirement against available system rails.

Part Context

This part belongs to the Renesas 71V321L family of dual-port SRAMs. The family offers various speed grades and packaging options, including PLCC and TQFP configurations. These devices are designed for applications requiring independent port access, distinguishing them from single-port alternatives.

Replacement Considerations

The 71V321L25JGI is documented as a similar alternative within the same manufacturer lineup, offering different performance characteristics.
