709269L12PFI

Memory IC Overview

The Renesas Electronics Corporation 709269L12PFI is a high-speed 256Kb (16K x 16) synchronous dual-port static random-access memory. It operates on a single 5V power supply with an access time of 12 ns and supports full synchronous operation on both ports. The device is housed in a 100-pin TQFP package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enables simultaneous independent access to the same memory location by two separate systems.
• Full synchronous operation on both ports ensures precise timing control for burst data flows.
• Configurable output modes allow selection between flow-through or pipelined data paths via a dedicated pin.
• Automatic power-down feature reduces standby power consumption when chip selects are inactive.

Memory IC Applications

• Bidirectional data transfer buffers in network communication systems
• High-speed cache memory in embedded processing architectures
• Data buffering for unidirectional or bidirectional burst transfers

Memory IC Procurement Notes

This component has reached end-of-life status and is no longer manufactured by Renesas Electronics Corporation. Verification of current availability requires checking authorized distributors for remaining stock or obsolete inventory. Procurement planning must account for potential supply constraints associated with discontinued parts.

Memory IC Selection Notes

Designers requiring this specific 12 ns synchronous dual-port SRAM should evaluate the 709279L12PFGI as a verified replacement option. Selection criteria must align with the original 5V TTL-compatible interface requirements and 100-pin TQFP footprint constraints to ensure mechanical and electrical compatibility.

Memory IC Part Context

The 709269 series belongs to Renesas' family of high-speed synchronous dual-port RAMs optimized for applications demanding rapid, simultaneous data access. These devices support depth expansion through dual chip enables without additional logic, facilitating scalable memory designs in complex electronic systems.

Memory IC Replacement Considerations

The 709279L12PFGI is listed as a similar substitute part number for the 709269L12PFI. Engineers should verify functional equivalence regarding pinout and voltage levels before implementation.
