709269S12PFI

Memory IC Overview

The Renesas Electronics Corporation 709269S12PFI is a high-speed, 256Kb (16K x 16-bit) synchronous dual-port static random-access memory (SRAM). It operates on a single 5V power supply and supports parallel interface access with a maximum access time of 12 ns. The device features full synchronous operation on both ports, allowing simultaneous independent access to the same memory location without conflict. It is housed in a 100-pin TQFP package and is designed for applications requiring unidirectional or bidirectional data flow bursts.

Memory IC Feature Summary

• Simultaneous dual-port access capability allows independent reading and writing to the same memory address by two separate processors.
• Full synchronous operation on both ports ensures reliable timing alignment for high-speed burst data transfers.
• Automatic power-down feature controlled by chip enable signals reduces standby power consumption during idle periods.

Memory IC Applications

• High-performance networking equipment requiring low-latency packet buffering
• Industrial automation systems needing fast data logging and retrieval
• Telecommunications infrastructure utilizing synchronous data processing

Memory IC Procurement Notes

Verify component authenticity through authorized distributors as this part may be obsolete. Confirm RoHS compliance status and lead times carefully since availability is limited. Ensure the specific suffix matches your design requirements for pinout and electrical characteristics before finalizing orders.

Memory IC Selection Notes

Select this component when simultaneous independent access to shared memory is required without external arbitration logic. Consider the 12 ns access speed and 5V operating voltage compatibility with existing system buses. Evaluate the 100-pin TQFP footprint against available board space and thermal management constraints.

Memory IC Part Context

This SRAM belongs to the 709269 series, optimized for burst data flows in synchronous environments. It complements other Renesas memory solutions by providing dedicated dual-port functionality for complex multi-processor architectures where data contention must be minimized.

Memory IC Replacement Considerations

Check for official substitute part numbers such as the 709279L12PFGI if the current model is discontinued. Verify that any replacement maintains identical pin configurations and electrical specifications to ensure seamless integration without redesigning the host circuitry.

Memory IC FAQ
