71V321L25PFG

Overview

The Renesas Electronics 71V321L25PFG is a static random access memory component featuring a 16 kbit storage capacity organized as 2K x 8. It operates with an asynchronous parallel interface and supports a supply voltage range of 3 V to 3.6 V. The device provides a maximum access time of 25 ns and has a maximum power supply current of 100 mA. It is designed for surface mount installation in a TQFP-64 package and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read and write operations
• Asynchronous operation without requiring a system clock signal
• Single 3.3 V power supply compatibility

Applications

• Data buffering in high-speed digital systems
• Cache memory implementation in embedded controllers
• FIFO buffer applications in communication interfaces

Procurement Notes

Verify the specific suffix PFG to confirm the TQFP-64 package type and Tray packaging format. Ensure the selected variant meets the required 0°C to +70°C commercial operating temperature range. Confirm RoHS compliance status through official manufacturer documentation before integration into the design.

Selection Notes

Select this part when a dual-port SRAM solution is required for independent port access. The 25 ns access speed suits moderate-to-high frequency asynchronous designs. Verify that the TQFP-64 footprint aligns with the PCB layout constraints and thermal management requirements of the target application environment.
