71V321L25PF

Memory IC Overview

The Renesas Electronics Corporation 71V321L25PF is a static random-access memory (SRAM) device belonging to the 71V321L25 series. It features a storage capacity of 16 kbit organized as 2k x 8 bits. The component utilizes an asynchronous parallel interface with a maximum access time of 25 ns. It operates within a supply voltage range of 3 V to 3.6 V and has a maximum power supply current of 100 mA. The device supports surface-mount installation in a TQFP-64 package and functions reliably across an operating temperature range from 0°C to +70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access by two masters
• Asynchronous operation for flexible system integration without clock synchronization
• Single 3.3 V power supply requirement for simplified board design

Memory IC Applications

• Data buffering in high-speed digital signal processing systems
• Cache memory implementation in embedded microcontroller architectures
• Temporary data storage in industrial control logic circuits

Memory IC Procurement Notes

Verify the specific suffix against official documentation, as packaging variations such as tray or reel configurations may exist within the same base model number. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement to ensure compatibility with assembly processes and environmental standards.

Memory IC Selection Notes

Select this component when a dual-port SRAM solution is required for applications needing independent read/write ports. Ensure the 25 ns access time meets the system timing constraints. Verify that the commercial temperature range of 0°C to +70°C aligns with the operational environment, distinguishing it from extended temperature variants available in the same series.

Memory IC Part Context

This part belongs to the Renesas 71V321L25 family of low-power dual-port SRAMs. The 'L' designation typically indicates low-voltage operation, while '25' specifies the speed grade. The 'PFG' suffix denotes the TQFP-64 plastic leaded chip carrier package type. This series provides non-volatile-like performance with volatile memory density for fast data handling tasks.

Memory IC Replacement Considerations

Direct substitutes include other 71V321L25 variants with compatible pinouts and electrical specifications. Check for differences in packaging (e.g., PLCC vs. TQFP) or temperature ranges before substitution.
