709269L15PF8

Memory IC Overview

The Renesas Electronics Corporation 709269L15PF8 is a high-speed synchronous dual-port static random-access memory (SRAM) with a density of 256 kilobits, organized as 16K words by 16 bits. It operates on a single 5V power supply and features full synchronous operation on both ports. The device supports flow-through or pipelined output modes selectable via the FT/PIPE pin. It includes counter enable and reset features for depth expansion without additional logic. The component utilizes separate upper-byte and lower-byte controls to ensure multiplexed bus compatibility. It is housed in a 100-pin TQFP package.

Memory IC Feature Summary

• Dual-port architecture enables simultaneous access to the same memory location from either port.
• Full synchronous operation on both ports with selectable flow-through or pipelined output modes.
• On-chip hardware support for depth expansion using dual chip enables without external logic.
• Automatic power down feature controlled by chip enables for low standby power consumption.

Memory IC Applications

• Applications requiring unidirectional data flow bursts
• Bidirectional data flow burst applications
• Systems utilizing multiplexed bus architectures

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm specific package markings and date codes against official documentation. Ensure environmental compliance requirements are met as RoHS status may vary. Validate that the synchronous interface timing matches system clock requirements before integration.

Memory IC Selection Notes

Select this component when simultaneous independent access to shared memory is required. The synchronous interface suits high-speed digital systems needing precise timing control. Consider the 100-pin TQFP package for surface-mount assembly needs. Evaluate the pipelined versus flow-through mode based on latency requirements.

Memory IC Part Context

This part belongs to the 709269 series of synchronous dual-port RAMs manufactured by Renesas Electronics. The series is designed for high-performance memory applications where data throughput and simultaneous access are critical. It complements other memory solutions by providing dedicated dual-port capabilities within a compact integrated circuit form factor.

Memory IC Replacement Considerations

Check for compatible synchronous dual-port SRAMs with similar 16K x 16 organization and 100-pin TQFP packaging. Verify electrical compatibility including voltage levels and access times. Ensure functional equivalence regarding port arbitration and byte control signals.
