7143SA35PF8

Overview

The Renesas Electronics Corporation 7143SA35PF8 is a high-speed, 32Kb (2K x 16) Dual-Port Static Random Access Memory. It features asynchronous parallel interface operation with a 35 ns access time. The device operates on a single 5V power supply within the 4.5V to 5.5V range and supports battery backup for data retention down to 2V. It is housed in a 100-pin TQFP package.

Feature Summary

• True dual-ported memory cells enable simultaneous independent access to the same memory location from both ports without conflict.
• On-chip port arbitration logic manages bus contention automatically, allowing full-speed error-free operation in 32-bit or wider systems without discrete logic.
• Supports versatile write control for lower and upper bytes of each port, facilitating easy expansion of data bus width.

Applications

• High-performance real-time processing systems requiring concurrent data access
• Master/Slave dual-port RAM configurations for expanding system data bus width
• Industrial equipment with strict timing requirements

Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence. Confirm package integrity and moisture sensitivity handling prior to assembly. Cross-reference datasheet revisions to ensure compatibility with existing design specifications.

Selection Notes

Select this component when simultaneous bidirectional access to shared memory is required. Ensure the design accommodates the 100-pin TQFP footprint and 5V logic levels. Verify that the 35 ns speed meets the system's timing constraints.

Part Context

This component belongs to the 7143SA series of dual-port SRAMs manufactured by Renesas Electronics. It utilizes the IDT MASTER/SLAVE approach for seamless integration into larger memory architectures. The series is designed for applications demanding high-speed, non-blocking memory operations.

Replacement Considerations

Consult official documentation for verified substitute part numbers. Generic equivalents may not support the specific master/slave arbitration logic or pinout configuration required for direct replacement.
