709279L9PF

Memory IC Overview

The Renesas Electronics Corporation 709279L9PF is a high-speed synchronous dual-port static random access memory (SRAM) with a total storage capacity of 512 kilobits. The device features a memory organization of 32K words by 16 bits and utilizes a parallel interface for data transfer. It supports a supply voltage range from 4.5 volts to 5.5 volts, ensuring compatibility with standard 5V logic systems. The component offers a maximum access time of 9 nanoseconds, facilitating rapid data retrieval in burst-oriented applications. It is housed in a 100-pin Thin Quad Flat Package (TQFP) designed for surface mount technology.

Memory IC Feature Summary

• True dual-port architecture enabling simultaneous independent access to the same memory location by two separate processors or controllers.
• Full synchronous operation on both ports, allowing for precise timing control and integration into high-speed digital systems.
• Automatic power-down functionality controlled by chip enable signals, permitting entry into low standby power modes when inactive.

Memory IC Applications

• High-speed data buffering in telecommunications equipment requiring unidirectional or bidirectional burst data flow.
• Network switch and router architectures utilizing dual-processor systems for packet processing and forwarding.
• Industrial automation controllers needing reliable, fast-access volatile memory for real-time state management.

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to obsolete status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check moisture sensitivity level handling procedures before assembly. Ensure pinout compatibility with existing PCB layouts. Validate that the 100-TQFP package dimensions match design specifications.

Memory IC Selection Notes

Select this component for designs requiring true dual-port SRAM with synchronous clocking. Consider the 9 ns access speed for high-frequency bus operations. Evaluate the 100-pin TQFP package for surface-mount assembly constraints. Assess power consumption profiles against system thermal limits. Verify that the 5V supply requirement aligns with the target platform's voltage rails.

Memory IC Part Context

This device belongs to the IDT 709279 series of synchronous dual-port RAMs. It is manufactured by Renesas Electronics Corporation following their acquisition of Integrated Device Technology assets. The part is designated as obsolete, indicating it is no longer actively produced for new designs. It serves as a legacy solution for systems requiring high-speed, non-volatile-free memory interfaces.

Memory IC Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation.
