7143SA25PF8

Overview

The Renesas 7143SA25PF8 is a high-speed 32Kb (2K x 16) dual-port static random-access memory. It operates with a maximum access time of 25 ns and supports a parallel interface. The device functions on a single 5V power supply, ranging from 4.5V to 5.5V. It features true dual-ported memory cells allowing simultaneous access to the same location. The component includes on-chip port arbitration logic and a BUSY input flag for control. It is available in a 100-pin TQFP package.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access to identical memory locations by both ports.
• Integrated on-chip port arbitration logic that facilitates full-speed operation in 32-bit or wider systems without discrete logic.
• Asynchronous operation capability from either port, supporting flexible system integration and data bus expansion.

Applications

• High-speed real-time engine applications requiring concurrent data processing
• Industrial equipment control systems utilizing dual-port communication
• Automotive monitoring functions and embedded sensor networks

Procurement Notes

Verify the specific suffix PF8 against official Renesas documentation to confirm the exact package type and temperature grade. Confirm current production status as some variants in this series may be discontinued. Ensure compatibility with existing board layouts for the 100-pin form factor before procurement.

Selection Notes

Select this component when a 2K x 16 organization is required for dual-port buffering. The 25 ns speed suits moderate-to-high frequency asynchronous interfaces. Verify voltage tolerance matches the 5V system rail. Consider package availability constraints for surface-mount assembly processes.

Part Context

This part belongs to the 7143 family of high-speed dual-port SRAMs. These devices are designed to replace complex discrete logic solutions in multi-port memory systems. The family supports various access times and packaging options to accommodate different industrial and commercial design requirements.

Replacement Considerations

Check for direct pin-compatible substitutes within the 7143 series. Verify if faster access time variants like the 20 ns version are functionally compatible. Ensure any replacement maintains the 100-pin TQFP footprint and 5V operating specifications.
