709269L12PF8

Memory IC Overview

The Renesas Electronics Corporation 709269L12PF8 is a high-speed 16K x 16 bit synchronous Dual-Port RAM. It features a 12 ns access time and operates on a single 5V power supply. The device supports flow-through or pipelined output modes selectable via the FT/PIPE pin, enabling simultaneous access to the same memory location. 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. The component is housed in a 100-pin TQFP package.

Memory IC Feature Summary

• Dual-port architecture allows simultaneous independent access to the same memory location by two processors.
• Full synchronous operation on both ports with selectable flow-through or pipelined output modes.
• Automatic power down feature controlled by CE0 and CE1 permits entry into very low standby power mode.

Memory IC Applications

• Applications requiring unidirectional data flow in bursts
• Applications requiring bidirectional data flow in bursts
• Systems utilizing multiplexed buses requiring byte matching compatibility

Memory IC Procurement Notes

Verify component authenticity through authorized channels as this part may be obsolete. Confirm RoHS compliance status and moisture sensitivity level (MSL) prior to assembly. Ensure proper handling procedures are followed due to surface mount packaging requirements. Check for available replacement alternatives if current supply is restricted.

Memory IC Selection Notes

Select this component when simultaneous dual-processor access to shared memory is required. Suitable for burst data transfer applications needing flexible output timing configurations. Verify voltage tolerance and temperature range alignment with system specifications before integration.

Memory IC Part Context
