7015L12PFI

Memory IC Overview

The Renesas Electronics Corporation 7015L12PFI is a high-speed, 8K x 9 Dual-Port Static RAM. It features true dual-ported memory cells allowing simultaneous reads of the same location. The device operates asynchronously with a 12 ns access time and supports TTL-compatible single 5V power supply. It includes on-chip port arbitration logic for busy and interrupt flags, along with hardware semaphore signaling support. The component is housed in an 80-pin TQFP package.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access to shared memory locations from two distinct ports.
• Integrated hardware support for semaphore signaling and port arbitration logic to manage data integrity between ports.
• Asynchronous operation capability allowing flexible timing control for both read and write cycles independently.

Memory IC Applications

• Stand-alone dual-port memory systems requiring high-speed data exchange.
• Master/Slave dual-port RAM configurations for expanding data bus widths to 18 bits or more.
• Industrial control applications utilizing asynchronous parallel interfaces.

Memory IC Procurement Notes

Verify component authenticity through authorized distributors as this part may be obsolete. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for available datasheets and pinout diagrams to ensure compatibility with existing PCB layouts. Validate lead-free status if required by specific environmental regulations.

Memory IC Selection Notes

Select this component when true dual-port functionality with hardware arbitration is required. Ensure system voltage matches the single 5V requirement. Verify that the 80-pin TQFP package fits the design constraints. Consider the 12 ns access time against system clock requirements. Evaluate the need for semaphore support for complex multi-port interactions.

Memory IC Part Context

The 7015 series represents a family of high-speed dual-port SRAMs designed for robust data handling. This specific model utilizes asynchronous technology suitable for diverse interface needs. It serves as a foundational memory solution for systems demanding concurrent access without external logic overhead.

Memory IC Replacement Considerations

Consult official documentation for direct substitutes. Verify pin compatibility and electrical specifications before replacing. Cross-reference with updated Renesas product lines for modern alternatives.
