707288L12PFI

Memory IC Overview

The 707288L12PFI is a 1 Mbit (128K x 8) dual-port static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It features asynchronous parallel interface operation with a maximum access time of 12 ns. The device operates within a supply voltage range of 3.0 V to 3.6 V and supports surface-mount installation in a 100-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm. It is designed for high-speed data buffering and storage applications requiring independent read/write ports.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access from two separate masters
• Asynchronous operation eliminating the need for an external clock signal
• Parallel interface supporting standard bus protocols for direct microprocessor connection

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Network switch and router packet processing buffers
• Embedded system cache memory for microcontrollers

Memory IC Procurement Notes

Verify component authenticity through authorized distributors or official Renesas channels. Confirm package integrity and pin alignment upon receipt. Check datasheet revisions for any updates to electrical characteristics or mechanical dimensions before final integration into production designs.

Memory IC Selection Notes

Select this component when independent concurrent access to shared memory is required without arbitration overhead. Ensure the design accommodates the 100-TQFP footprint and thermal requirements. Verify that the 12 ns access speed meets the system timing constraints for the target application frequency.

Memory IC Part Context

This part belongs to the 707288 series of dual-port SRAMs, which are optimized for applications needing fast, non-blocking data exchange between processors or peripherals. The series provides reliable volatile storage solutions for industrial and commercial environments.

Memory IC Replacement Considerations

Check for direct pin-compatible substitutes within the same Renesas family. Verify that alternative parts match the 12 ns access time, 3.0-3.6 V supply range, and 100-TQFP package dimensions to ensure mechanical and electrical compatibility.
