709269S15PF8

Memory IC Overview

The 709269S15PF8 is a high-speed synchronous Dual-Port RAM manufactured by Renesas Electronics Corporation. It features a memory organization of 16K x 16 bits, providing a total density of 256 Kbit. The device operates with a parallel interface and supports a 15 ns access time. It requires a single 5V power supply within the ±10% tolerance range. The component is housed in a 100-pin TQFP package (14x14 mm) and is designed for applications requiring synchronized data flow in bursts.

Memory IC Feature Summary

• Dual-port architecture allows simultaneous independent access to the same memory location from both ports.
• Full synchronous operation on both ports ensures precise timing control for burst data flows.
• Automatic power-down feature controlled by chip enables reduces standby power consumption.
• Separate upper-byte and lower-byte controls enable multiplexed bus compatibility.

Memory IC Applications

• Applications requiring unidirectional or bidirectional data flow in bursts
• Systems needing synchronized data flow between two processors or controllers
• High-speed buffer memory in digital signal processing architectures

Memory IC Procurement Notes

Verify component authenticity through authorized distributors as this part may be subject to obsolescence notices. Confirm RoHS compliance status, as specific variants may not meet current environmental regulations. Check for moisture sensitivity level requirements during storage and handling. Ensure the 100-TQFP package dimensions match your PCB footprint design constraints before finalizing procurement orders.

Memory IC Selection Notes

Select this component when dual-port simultaneous access is required for burst data transfers. The 15 ns speed suits moderate-to-high frequency synchronous systems. Consider the 5V supply requirement against system voltage rails. Evaluate the 100-pin TQFP package availability against assembly capabilities. Compare against asynchronous alternatives if pipeline latency is not critical for the specific application timing.

Memory IC Part Context

This part belongs to the Renesas 709269 series of synchronous dual-port SRAMs. It shares architectural similarities with other members like the 709279 series but differs in density and speed grades. The 'S' suffix typically denotes specific speed or temperature variations within the product line. It is often used in legacy industrial and communication equipment designs requiring reliable dual-access memory.

Memory IC Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-reference compatibility with IDT equivalents if applicable, ensuring pinout and electrical specifications match exactly.
