709279L12PFI

Memory IC Overview

The Renesas 709279L12PFI is a 512Kb (32K x 16) synchronous dual-port SRAM housed in a 100-pin TQFP package. It operates on a single 5V supply with an access time of 12 ns and supports industrial temperatures from -40°C to +85°C. The device features full synchronous operation, flow-through or pipelined modes, and automatic power-down capabilities.

Memory IC Feature Summary

• Dual-port architecture enables simultaneous independent access to memory locations by two processors.
• Full synchronous operation on both ports ensures precise timing control for high-speed data transfer.
• Automatic power-down feature reduces standby current when chip selects are deasserted.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Network switch and router packet storage
• Industrial automation control systems

Memory IC Procurement Notes

This component is officially obsolete and no longer manufactured. Verify availability through authorized distributors for remaining stock only. Confirm RoHS compliance status as the original part does not meet current standards. Check for valid replacement alternatives before finalizing procurement plans.

Memory IC Selection Notes

Select this part only if legacy compatibility with existing 5V synchronous designs is required. Consider the 709279L12PFGI for updated manufacturing runs. Evaluate pinout and electrical similarities against modern replacements to ensure seamless integration without redesigning the host system.

Memory IC Part Context

Part of the 709279L series of high-speed synchronous dual-port RAMs. Designed for burst data flow applications requiring unidirectional or bidirectional communication between two masters sharing a common memory space within industrial temperature ranges.

Memory IC Replacement Considerations

The 709279L12PFGI is listed as a similar alternative by the manufacturer. Verify functional equivalence and packaging compatibility before substitution.
