709269S15PFG

Memory IC Overview

The Renesas 709269S15PFG is a high-speed 16K x 16 bit synchronous Dual-Port Static RAM. It features full synchronous operation on both ports, allowing simultaneous access to the same memory location. The device supports Flow-Through or Pipelined output modes selectable via the FT/PIPE pin. It operates with a single 5V (±10%) TTL-compatible power supply and includes separate upper-byte and lower-byte controls for multiplexed bus compatibility.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous read/write access to shared memory locations without external arbitration logic
• Configurable output modes supporting either Flow-Through or Pipelined data paths on either port
• Integrated automatic power-down functionality controlled by chip enables to minimize standby power consumption
• Hardware support for depth expansion using dual chip enables without requiring additional discrete logic

Memory IC Applications

• High-speed burst data flow systems requiring unidirectional or bidirectional transfer
• Multiprocessor architectures utilizing master/slave dual-port configurations
• Industrial control systems demanding low standby power and synchronous timing

Memory IC Procurement Notes

Verify the specific suffix 'S' against official Renesas documentation to confirm package type and temperature grade. Confirm RoHS compliance status as older variants may differ. Check current lifecycle status for availability of samples or production units. Ensure the 100-pin TQFP footprint matches your PCB design constraints. Validate that the synchronous interface timing aligns with your system clock requirements.

Memory IC Selection Notes

Select this component when synchronous dual-port access is required for high-throughput applications. It is suitable for designs needing independent port control with byte-level granularity. Consider the pipelined mode for higher clock frequencies. Verify that the 5V supply voltage matches your system rails. Ensure the 100-pin TQFP package fits within your spatial limitations.

Memory IC Part Context

This part belongs to the IDT 709269 series of synchronous dual-port RAMs. It is designed for applications requiring fast, concurrent memory access. The series offers flexibility in data path configuration through selectable output modes. It serves as a key component in systems needing efficient data buffering between asynchronous or synchronous domains.

Memory IC Replacement Considerations

Check for direct pin-to-pin replacements within the 709269 family with different access times. Verify if newer Renesas or IDT synchronous DPRAM models offer improved power efficiency. Ensure any substitute maintains the 100-pin TQFP package and 5V operating voltage.
