709279L9PF8

Memory IC Overview

The Renesas Electronics Corporation 709279L9PF8 is a 512 Kbit (32K x 16) synchronous dual-port static random-access memory. It features a parallel interface with a maximum access time of 9 ns and operates on a single 4.5 V to 5.5 V power supply. The device is housed in a 100-pin TQFP package with dimensions of 14x14 mm. It supports surface-mount installation and functions within an operating temperature range of 0°C to +70°C.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access to the same memory location by two separate controllers.
• Full synchronous operation on both ports supporting flow-through or pipelined output modes selectable via control pins.
• Automatic power-down capability controlled by chip enables, allowing on-chip circuitry to enter low standby power mode.

Memory IC Applications

• High-speed data buffering for unidirectional or bidirectional burst data flows
• Network switch and router packet buffering systems
• Embedded controller cache memory applications

Memory IC Procurement Notes

Verify component authenticity through authorized channels as this part is discontinued. Confirm moisture sensitivity level 3 compliance and lead-free status requirements against current design specifications. Ensure proper handling procedures are followed due to humidity sensitivity. Validate that the 100-TQFP footprint matches existing PCB layouts before finalizing procurement decisions.

Memory IC Selection Notes

Select this component when simultaneous dual-controller access to 32K x 16 memory is required. Choose based on the 9 ns access speed and 5V TTL-compatible I/O levels. Consider the 100-pin TQFP package constraints and commercial temperature range limits during system integration planning.

Memory IC Part Context

This device belongs to the 709279L series of high-speed synchronous dual-port SRAMs. It shares architectural similarities with other members like the 709289L but offers lower density. The series is designed for burst data flow optimization without requiring additional discrete logic for depth expansion.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include IDT709279L9PF8. Verify pinout compatibility and electrical specifications before substitution.
