709289L9PFI

Memory IC Overview

The Renesas Electronics 709289L9PFI is a high-speed 64K x 16 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 supports flow-through or pipelined output modes on either port via dedicated FT/PIPE 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 TQFP package.

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 external pins
• Integrated address counter with enable and reset capabilities for burst operations
• Dual chip enables facilitating depth expansion configurations without external logic

Memory IC Applications

• High-speed unidirectional data flow applications
• Bidirectional data flow burst processing systems
• Depth expansion memory configurations requiring multiple chip control
• Multiplexed bus interfaces utilizing separate byte controls

Memory IC Procurement Notes

Verify the specific speed grade and temperature range requirements against the datasheet specifications before procurement. Confirm that the 100-pin TQFP package dimensions align with the target PCB layout constraints. Ensure the design accommodates the required 5V power supply tolerance and check for moisture sensitivity handling procedures during assembly.

Memory IC Selection Notes

Select this component when simultaneous independent access to shared memory locations is required. Consider the pipelined mode for higher throughput applications or flow-through mode for simpler latency requirements. Evaluate the need for internal address counters versus external address generation based on system complexity and interface timing constraints.
