709279S9PF8

Memory IC Overview

The 709279S9PF8 is a high-speed synchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics. It features a storage capacity of 512 kbit organized as 32K x 16 bits. The device supports parallel interface operation with a maximum access time of 9 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and is designed for surface-mount installation in a 100-pin TQFP package. The component is classified as an obsolete product.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access to the same memory location from two separate ports.
• Full synchronous operation on both ports, optimized for applications requiring unidirectional or bidirectional data flow in bursts.
• Automatic power-down feature controlled by chip enable signals to reduce standby power consumption.

Memory IC Applications

• High-speed data buffering in burst transfer systems
• Bidirectional data flow processing in communication interfaces
• Unidirectional data flow processing in embedded control systems

Memory IC Procurement Notes

This component is officially discontinued and no longer in production. Verification of availability should focus on surplus distributors or secondary markets rather than direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to procurement, as these specifications may vary based on original manufacturing date and storage history.

Memory IC Selection Notes

Select this part only if the design requires a 32K x 16 synchronous dual-port SRAM with 9 ns access time and 5V logic compatibility. Verify that the 100-pin TQFP package fits the PCB layout constraints. Consider that the device is obsolete; ensure long-term supply stability is not critical or that adequate stock exists for the required lifecycle.

Memory IC Part Context

The 709279 series belongs to Renesas' family of high-speed synchronous dual-port RAMs. These devices are engineered for performance-critical applications where simultaneous read/write operations from two masters are necessary. The S9 suffix typically denotes specific speed grades and packaging options within the broader 709279 product line.

Memory IC Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, alternative sourcing must rely on cross-reference tools or equivalent functional replacements from other manufacturers, subject to pinout and electrical parameter verification.
