709079S12PF8

Memory IC Overview

The Renesas Electronics Corporation 709079S12PF8 is a high-speed 32K x 8-bit synchronous dual-port static RAM. It features true dual-ported memory cells allowing simultaneous access to the same location from both ports. The device operates on a single 5V power supply and supports flow-through or pipelined output modes selectable via the FT/PIPE pin. It includes counter enable and reset features for address generation, with full synchronous operation on both ports.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access to any memory location from both ports.
• Configurable flow-through or pipelined output modes selectable via the dedicated FT/PIPE control pin.
• Integrated address counter with enable and reset capabilities for automated sequential addressing.
• Dual chip enables (CE0 and CE1) facilitating depth expansion without requiring additional external logic.

Memory IC Applications

• High-speed data buffering in burst transfer applications
• Bidirectional data flow systems requiring simultaneous port access
• Depth expansion configurations using multiple chip enables

Memory IC Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence notices. Confirm package integrity upon receipt, specifically checking for moisture sensitivity indicators given the TQFP construction. Ensure voltage levels match the specified 5V requirement before integration into target circuits.

Memory IC Selection Notes

Select this component when simultaneous bidirectional access to shared memory locations is required. The choice between flow-through and pipelined modes depends on system latency requirements. Verify that the 5V supply tolerance aligns with the design constraints and that the 100-pin TQFP footprint fits the PCB layout.

Memory IC Part Context

This device belongs to the IDT709089/79 family of synchronous dual-port SRAMs. It shares architectural similarities with the 709089 variant but offers a reduced density of 32K x 8 bits compared to the 64K x 8 configuration. Both variants utilize the same 100-pin TQFP package and support identical interface protocols.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include IDT709079L12PF8 and IDT709079S12PF. Verify compatibility regarding speed grade and power consumption characteristics before substitution.
