709269S12PFG8

Memory IC Overview

The 709269S12PFG8 is a high-speed synchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics. It features a storage organization of 16K words by 16 bits, providing a total capacity of 256 kilobits. The device supports a maximum clock frequency of 83 MHz and offers an access time of 12 nanoseconds. It operates on a single 5V power supply with a voltage range of 4.5V to 5.5V. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) suitable for surface-mount technology.

Memory IC Feature Summary

• Dual-port architecture enables simultaneous independent access to the same memory location from both ports without conflict.
• Full synchronous operation on both ports allows for flexible flow-through or pipelined output modes selectable via control pins.
• Integrated automatic power-down feature reduces standby power consumption when chip enables are deactivated.
• Supports depth expansion through dual chip enable inputs without requiring additional external logic.

Memory IC Applications

• High-speed data buffering in network communication equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial automation controllers
• Signal processing applications requiring burst data flow

Memory IC Procurement Notes

Verify component authenticity and physical condition upon receipt, as this part may be subject to obsolescence notices. Confirm that the package marking matches the specified 100-pin TQFP configuration. Ensure handling procedures comply with moisture sensitivity level requirements during soldering. Review official discontinuation notifications for availability constraints and long-term supply risks before finalizing design-in decisions.

Memory IC Selection Notes

Select this component when a system requires true dual-port capability with synchronous timing for complex data sharing between processors. The 12-nanosecond access time suits applications needing moderate speed with low power standby modes. Consider the 100-pin TQFP footprint for board layout compatibility. Evaluate if the 5V logic interface aligns with the target system's voltage levels compared to lower voltage alternatives.

Memory IC Part Context

This device belongs to the 709269 series of synchronous dual-port SRAMs, designed for high-performance memory applications. The series typically includes variants with different access times and packaging options. These components are engineered to replace older asynchronous dual-port memories in modern synchronous designs, offering improved timing predictability and reduced external logic requirements for bus matching.

Memory IC Replacement Considerations

Check for direct pin-compatible upgrades within the 709269 family, such as faster access time variants like the 709269S10. Verify that any substitute maintains the 100-pin TQFP package and 5V operating voltage. Ensure the replacement supports the required synchronous mode and dual-port arbitration features necessary for the specific application design.
