709079S15PFI8

Memory IC Overview

The Renesas Electronics Corporation 709079S15PFI8 is a high-speed 32K x 8 bit synchronous Dual-Port Static RAM. It features true dual-ported memory cells allowing simultaneous access of the same location from both ports. The device operates on a single 5V (±10%) TTL-compatible power supply and supports flow-through or pipelined output modes selectable via the FT/PIPE pin. It includes counter enable and reset features, dual chip enables for depth expansion without additional logic, and an automatic power-down feature controlled by CE0 and CE1.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access to any address from both ports
• Full synchronous operation with registered inputs providing minimal setup and hold times for control, data, and address signals
• Configurable flow-through or pipelined output modes selectable via dedicated hardware pins
• Integrated address counter with enable and reset capabilities for burst data flow applications

Memory IC Applications

• High-speed unidirectional or bidirectional data flow in burst mode systems
• Depth expansion configurations utilizing dual chip enables without external logic
• Applications requiring simultaneous read/write operations across two independent ports

Memory IC Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and moisture sensitivity handling requirements prior to assembly. Ensure compatibility with existing system voltage levels and timing constraints. Review datasheet specifications for absolute maximum ratings to prevent operational damage during integration.

Memory IC Selection Notes

Select this component for designs requiring synchronous dual-port memory with specific speed grades. Consider the S suffix for standard power consumption versus L suffix for low-power variants. Verify temperature range availability as industrial options may differ from commercial offerings. Evaluate pipelined versus flow-through mode requirements based on system latency needs.

Memory IC Part Context

This part belongs to the IDT709089/79 family of high-speed synchronous dual-port static RAMs. The '709079' designation indicates a 32K x 8 organization, distinguishing it from the 64K x 8 variant. The 'S' denotes standard power consumption, while 'L' indicates low power. The '15' specifies the 15ns speed grade available in commercial temperature ranges.

Memory IC Replacement Considerations

Compatible substitutes include other members of the IDT709089/79 series such as the 709079S12PFI8 or 709079S9PFI8 for faster speeds. Cross-reference with Renesas-branded equivalents if IDT inventory is unavailable. Verify pinout compatibility and electrical characteristics before substitution.
