709279L12PFI8

Memory IC Overview

The 709279L12PFI8 is a high-speed 32K x 16 bit synchronous Dual-Port RAM optimized for burst data flow applications. It features full synchronous operation on both ports with selectable Flow-Through or Pipelined output modes via the FT/PIPE pin. The device supports simultaneous access to the same memory location and includes counter enable/reset features. It operates on a single TTL-compatible 5V power supply and is available in a 100-pin TQFP package.

Memory IC Feature Summary

• Dual-Port architecture allows simultaneous independent access of the same memory location by two processors.
• Configurable output mode enables selection between Flow-Through and Pipelined operations on either port.
• Automatic power down feature controlled by chip enables permits entry into very low standby power mode.
• Full synchronous operation on both ports ensures compatibility with high-speed digital systems.

Memory IC Applications

• High-speed data buffering in unidirectional or bidirectional burst transfer systems
• Network switch and router packet buffering
• Digital signal processing (DSP) cache memory
• Telecommunications equipment interface storage

Memory IC Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence notices. Confirm moisture sensitivity level handling requirements prior to assembly. Check for specific RoHS compliance status as older variants may not meet current environmental standards. Validate package marking against official datasheet specifications to ensure correct revision identification.

Memory IC Selection Notes

Select this component when dual-port simultaneous access is required without external arbitration logic. Ensure system timing aligns with the specified 12 ns access time. Verify that the 5V supply voltage matches the design constraints. Consider the 100-pin TQFP footprint for PCB layout planning. Evaluate whether pipelined or flow-through mode best suits the target application's latency requirements.

Memory IC Part Context

This device belongs to the Renesas 709279 series of synchronous dual-port SRAMs. It shares architectural similarities with other members like the 709289 but differs in density and speed grades. The series is designed for embedded memory applications requiring high bandwidth and low latency. It replaces earlier asynchronous dual-port solutions in modern high-speed digital designs.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include 709279L12PF, 709279L12PFGI, and 709279L12PFI. These variants share identical electrical characteristics and pinouts but differ in packaging type or lead-free status. Verify package dimensions and moisture sensitivity levels before substitution.
