709269L12PFI8

Memory IC Overview

The 709269L12PFI8 is a high-speed 16K x 16 bit synchronous Dual-Port Static Random Access Memory (SRAM) manufactured by Renesas Electronics Corporation. It features a parallel interface with a maximum access time of 12 ns and operates on a single 5V power supply within the 4.5V to 5.5V range. The device supports both flow-through and pipelined output modes, selectable via the FT/PIPE pin. It is housed in a 100-pin TQFP package with dimensions of 14x14 mm and is rated for an industrial operating temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enables simultaneous independent access to memory locations from two separate ports.
• Configurable output mode allows selection between flow-through and pipelined operations for optimized data throughput.
• Integrated automatic power-down feature reduces standby current when chip enables are deactivated.
• Supports depth expansion through dual chip enable inputs without requiring additional external logic.

Memory IC Applications

• High-speed burst data transfer systems requiring unidirectional or bidirectional flow
• Network switching equipment and telecommunications infrastructure
• Industrial control systems with strict timing requirements
• Embedded storage buffers in consumer electronics

Memory IC Procurement Notes

Verify component authenticity as this part is obsolete. Confirm RoHS compliance status, as older batches may not meet current environmental standards. Check moisture sensitivity level handling requirements during assembly. Ensure replacement parts match voltage and timing specifications. Validate package integrity upon receipt.

Memory IC Selection Notes

Select this component for applications requiring synchronous dual-port memory with low latency. Compare against asynchronous alternatives if bus synchronization is not required. Consider power consumption differences between flow-through and pipelined modes. Verify thermal performance within the specified industrial temperature range.

Memory IC Part Context

This SRAM belongs to the 709269 series, designed for high-performance memory buffering. It complements other dual-port RAM families like the 70V261 and 70261, offering synchronous operation advantages over asynchronous variants. The 100-TQFP package provides a compact footprint suitable for dense PCB layouts in modern electronic devices.

Memory IC Replacement Considerations

The 709279L12PFGI is listed as a similar alternative. Verify compatibility regarding memory organization, access times, and package dimensions before substitution. Ensure the replacement maintains synchronous operation and voltage requirements.
