709269L9PF8

Memory IC Overview

The Renesas Electronics Corporation 709269L9PF8 is a high-speed synchronous dual-port static random-access memory (SRAM) device. It features a storage organization of 16K words by 16 bits, providing a total capacity of 256 kilobits. The component operates with a single 5V power supply and supports parallel interface communication. Key electrical specifications include a maximum access time of 9 nanoseconds and a maximum operating frequency of 111 MHz. The device is housed in a 100-pin Thin Quad Flat Package (TQFP) suitable for surface-mount technology applications.

Memory IC Feature Summary

• Dual-Port architecture enables simultaneous independent access to the same memory location from two separate ports.
• Full synchronous operation on both ports ensures precise timing control via clock signals.
• Configurable output modes allow selection between Flow-Through or Pipelined data paths via dedicated control pins.
• Integrated automatic power-down feature reduces standby current when chip enables are deactivated.

Memory IC Applications

• High-speed data buffering in network switching equipment
• Cache memory implementation in embedded processing systems
• Data acquisition systems requiring low-latency bidirectional transfer

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to potential obsolescence status. Confirm moisture sensitivity level handling requirements prior to assembly. Check for specific RoHS compliance variations across manufacturing lots. Validate pinout compatibility with existing PCB footprints. Review datasheet revisions for any functional updates or recommended design changes.

Memory IC Selection Notes

Select this component for designs requiring concurrent read/write operations without arbitration logic. Ensure system voltage aligns with the specified 5V TTL-compatible supply range. Consider thermal dissipation capabilities within the TQFP package for high-frequency operation. Evaluate bus width requirements against the 16-bit data path. Verify that the target application benefits from synchronous timing over asynchronous alternatives.

Memory IC Part Context

This part belongs to the Renesas 709269 series of synchronous dual-port RAMs. It shares architectural similarities with other members like the 709279 and 709289, differing primarily in density and speed grades. The series is designed for burst data flow optimization in unidirectional or bidirectional applications.

Memory IC Replacement Considerations

Direct substitutes may include the 709269L12PF8 for slower speed requirements or the 709279 series for higher density needs. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
