709289L12PFI

Memory IC Overview

The Renesas Electronics Corporation 709289L12PFI is a high-speed 64K x 16 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 supports flow-through or pipelined output modes on either port via dedicated pins. It includes counter enable and reset features, dual chip enables for depth expansion without additional logic, and separate upper-byte and lower-byte controls. The component operates with a single 5V (±10%) TTL-compatible power supply and is available in a 100-pin Thin Quad Flatpack (TQFP) package.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous access to any address from both ports
• Configurable flow-through or pipelined output modes selectable via FT/PIPE pins
• Integrated address counter with enable and reset capabilities for burst data flow applications
• Dual chip enables facilitating depth expansion configurations without external logic

Memory IC Applications

• Systems requiring unidirectional or bidirectional data flow in bursts
• Depth expansion memory configurations utilizing multiple devices
• Applications demanding simultaneous independent access to shared memory locations

Memory IC Procurement Notes

Verify component authenticity through authorized channels as this part may be obsolete. Confirm specific speed grade and temperature range availability against current manufacturer documentation. Ensure proper handling procedures are followed due to moisture sensitivity classification. Cross-reference pinout compatibility if integrating into existing designs.

Memory IC Selection Notes

Select based on required clock cycle time and output mode preference between flow-through and pipelined operations. Consider the industrial temperature range availability if operating conditions exceed commercial limits. Evaluate depth expansion requirements to determine if dual chip enable features meet system scaling needs. Verify voltage compatibility with the single 5V supply specification.
