709269L12PFGI

Memory IC Overview

The Renesas Electronics Corporation 709269L12PFGI is a high-speed 16K x 16 bit synchronous Dual-Port Static Random Access Memory (SRAM). It features a parallel interface with a 12 ns access time and operates on a single 5V power supply within the 4.5V to 5.5V range. The device supports simultaneous independent access by two processors to the same memory location. It is housed in a 100-pin TQFP package measuring 14x14 mm and supports an industrial operating temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enables simultaneous, independent access to shared memory locations by two separate processors without conflict.
• Full synchronous operation on both ports ensures precise timing alignment for high-speed data transfer applications.
• Automatic power-down functionality allows on-chip circuitry to enter low standby mode when controlled by specific chip enable signals.

Memory IC Applications

• High-speed data buffering in telecommunications equipment requiring burst data flow management.
• Network switching systems utilizing unidirectional or bidirectional data paths.
• Industrial control systems needing reliable dual-processor memory sharing within specified temperature ranges.

Memory IC Procurement Notes

Verify component authenticity through authorized distributors as this part may be obsolete. Confirm RoHS compliance status since earlier variants were non-compliant. Check for lead-free alternatives if environmental regulations require it. Ensure the 100-TQFP footprint matches your PCB design constraints before procurement.

Memory IC Selection Notes

Select this component when simultaneous dual-processor access to a 256Kb memory space is required. It is suitable for designs needing 12 ns latency with a standard 5V logic interface. Consider the 100-pin TQFP package size for board layout planning. Verify that the synchronous clocking requirements align with your system's timing architecture.

Memory IC Part Context

This device belongs to the 709269L series of synchronous dual-port SRAMs from Renesas. It shares architectural similarities with other members like the 709279L but differs in storage density. The series is designed for applications demanding high throughput and flexible bus compatibility through separate byte controls.

Memory IC Replacement Considerations

The 709279L12PFGI is listed as a similar replacement option. Note that the 709279L typically offers higher density (32K x 16) compared to the 709269L (16K x 16). Verify pinout compatibility and electrical specifications before substitution.
