709289L9PFI8

Memory IC Overview

The Renesas Electronics Corporation 709289L9PFI8 is a high-speed 64K x 16 bit synchronous Dual-Port Static RAM. It features true dual-port memory cells allowing simultaneous access of 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 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 for multiplexed bus compatibility.

Memory IC Feature Summary

• True dual-port architecture enabling simultaneous access to identical memory locations
• Full synchronous operation with registered inputs for minimal setup and hold times
• Configurable flow-through or pipelined output modes selectable via external pins
• Integrated address counter with enable and reset capabilities for burst operations

Memory IC Applications

• High-speed data buffering in unidirectional or bidirectional burst flows
• Depth expansion configurations utilizing dual chip enables
• Multiplexed bus systems requiring separate byte control

Memory IC Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package integrity as the unit utilizes a 100-pin TQFP configuration. Ensure proper handling procedures are followed due to moisture sensitivity classification. Cross-reference ordering suffixes to verify specific speed grades and temperature ranges required for the target application environment.

Memory IC Selection Notes

Select this component when simultaneous independent access to shared memory is required. The synchronous interface simplifies timing constraints compared to asynchronous alternatives. Consider the pipelined mode for higher throughput applications or flow-through for simpler latency requirements. Verify that the system voltage aligns with the specified 5V tolerance range and that thermal conditions remain within the commercial operating limits.
