7143SA55PF8

Overview

The Renesas Electronics Corporation 7143SA55PF8 is a high-speed 2K x 16 Dual-Port Static RAM. It features true dual-ported memory cells allowing simultaneous access to the same location. The device operates asynchronously with a 55 ns access time and supports a single 5V power supply. It includes on-chip port arbitration logic and a BUSY input for master/slave configurations. The component is housed in a 100-pin TQFP package.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access from both ports.
• On-chip port arbitration logic with BUSY input for seamless master/slave expansion without discrete logic.
• Separate write control for lower and upper bytes of each port, facilitating data bus width expansion.

Applications

• High-speed parallel processing systems requiring concurrent data access.
• Master/slave dual-port RAM configurations for wider memory buses.
• Industrial applications within the commercial temperature range.

Procurement Notes

Verify component authenticity due to discontinued status. Confirm RoHS compliance as indicated by specific manufacturer markings. Check moisture sensitivity level handling requirements during storage and assembly. Validate pin compatibility with existing PCB footprints before integration.

Selection Notes

Select this part for applications requiring asynchronous dual-port SRAM with 55 ns speed. Ensure system voltage matches the 4.5V to 5.5V operating range. Consider the 100-pin TQFP package constraints for layout. Evaluate if the 2K x 16 density meets specific memory capacity needs.

Part Context

This component belongs to the 7143SA series of dual-port SRAMs manufactured by Renesas Electronics. It is an evolution of earlier IDT designs, maintaining functional compatibility while adhering to Renesas manufacturing standards. The series is designed for robust performance in embedded memory applications.

Replacement Considerations
