709079L12PF8

Memory IC Overview

The Renesas Electronics Corporation 709079L12PF8 is a 32K x 8 bit synchronous Dual-Port Static RAM. It features true dual-port memory cells allowing simultaneous access to the same location from both ports. The device operates on a single 5V (±10%) power supply and supports Flow-Through or Pipelined output modes via the FT/PIPE pin. It includes counter enable and reset features, dual chip enables for depth expansion, and full synchronous operation with minimal setup and hold times.

Memory IC Feature Summary

• True dual-port architecture enabling simultaneous access of any address from both ports
• Configurable Flow-Through or Pipelined output modes selectable via the FT/PIPE pin
• Integrated address counter with enable and reset capabilities for burst data flow applications
• Dual chip enables facilitating depth expansion without additional external logic

Memory IC Applications

• Applications requiring unidirectional or bidirectional data flow in bursts
• Systems utilizing depth expansion configurations through multiple chip enables
• High-speed synchronous memory interfaces optimized for low latency

Memory IC Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches the 100-pin TQFP format. Ensure operating voltage aligns with the required 5V supply range. Check for industrial temperature grade availability if environmental conditions exceed commercial limits. Validate ordering suffixes for specific packaging requirements such as tape and reel versus tube.

Memory IC Selection Notes

Select this component when simultaneous independent access to shared memory locations is required. Choose between Flow-Through and Pipelined modes based on system timing constraints and throughput needs. Consider the integrated address counter for simplified sequential access control. Verify that the 100-pin TQFP package fits the board layout constraints. Ensure the 5V logic level compatibility matches the host system interface.

Memory IC Part Context

This part belongs to the IDT709089/79 family of high-speed synchronous dual-port SRAMs. It represents the 32K x 8 density variant within the series. The 'L' suffix indicates low-power consumption characteristics compared to standard power versions. The '12' denotes the 12ns maximum clock-to-data access time suitable for commercial and industrial temperature ranges.

Memory IC Replacement Considerations

IDT709079L12PFGI serves as an industrial temperature grade alternative. IDT709079L12PF8 is the tape and reel packaging equivalent. IDT709079S12PF offers standard power consumption options. Verify pinout and electrical parameters before substitution.
