709279L12PF8

Memory IC Overview

The Renesas Electronics Corporation 709279L12PF8 is a synchronous dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 512 kbit, organized as 32K x 16 bits. The device supports parallel interface operation with an access time of 12 ns. It operates on a single 5V power supply within a voltage range of 4.5 V to 5.5 V. The component is housed in a 100-pin TQFP package and is designed for surface mount installation. It functions within a commercial temperature range of 0°C to +70°C.

Memory IC Feature Summary

• Dual-port architecture enables simultaneous independent access to the same memory location by two separate controllers.
• Full synchronous operation on both ports ensures precise timing control for high-speed data transfer applications.
• Automatic power-down feature controlled by chip enable signals allows entry into low standby power mode.

Memory IC Applications

• High-speed data buffering in burst data flow systems
• Bidirectional communication interfaces requiring simultaneous read/write capabilities
• Industrial control systems utilizing synchronous logic

Memory IC Procurement Notes

This component is officially listed as obsolete or discontinued by the manufacturer. Verification of current availability through authorized distributors is required, as stock may be limited to surplus inventory. Ensure compatibility with existing system designs before procurement, as end-of-life status may impact long-term supply stability.

Memory IC Selection Notes

Select this part for applications requiring synchronous dual-port memory with 16-bit width and 12 ns speed. Verify that the 100-pin TQFP package fits the PCB layout constraints. Confirm that the 5V operating voltage aligns with the system power rails. Consider the commercial temperature range suitability for the intended environment.

Memory IC Part Context

The 709279 series belongs to Renesas' family of high-speed synchronous dual-port RAMs. These devices are optimized for unidirectional or bidirectional data flow bursts. The series typically offers flow-through or pipelined output modes and includes counter features for depth expansion without additional logic.
