71V321LA25PF8

Overview

The Renesas Electronics Corporation 71V321LA25PF8 is a dual-port static random-access memory (SRAM) device organized as 2K x 8 bits, providing a total storage capacity of 16 Kbit. It operates on a single 3.3V power supply with a voltage range of 3.0V to 3.6V and features asynchronous parallel interfaces for both ports. The component supports a maximum access time of 25 ns and draws a maximum supply current of 130 mA. It is housed in a 64-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm and is rated for an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous interface supporting flexible timing requirements without external clock signals
• Industrial-grade temperature rating suitable for demanding environmental conditions

Applications

• Buffering data between high-speed processors and slower peripheral devices
• Cache memory implementation in embedded control systems
• Data logging applications requiring rapid temporary storage

Procurement Notes

Verify the specific suffix 'PF8' against official Renesas documentation to confirm package type and moisture sensitivity level. Ensure compatibility with existing board layouts regarding the 64-TQFP footprint. Confirm RoHS compliance status through current manufacturer declarations before finalizing procurement plans.

Selection Notes

Select this component when independent dual-port access is required for concurrent data handling. The 25 ns speed suits moderate-frequency asynchronous buses. Verify that the 64-TQFP package fits the available PCB space and thermal constraints within the specified industrial temperature range.

Part Context

This part belongs to the 71V321L series of low-power dual-port SRAMs. It shares architectural similarities with other variants like the 71V321S25 but offers extended temperature capabilities. The series is designed for applications needing reliable, fast, non-volatile-free memory solutions in compact packages.

Replacement Considerations

Official upgrades include the 71V321L25PFG8 and 71V321L25PFGI8. These alternatives maintain functional compatibility while potentially offering updated packaging or compliance standards.
