709269S7PFG

Memory IC Overview

The 709269S7PFG is a dual-port synchronous static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a total storage capacity of 256 Kbit, organized as 16K words by 16 bits. The device operates within a supply voltage range of 4.5V to 5.5V and supports parallel interface communication. It is housed in a 100-TQFP surface-mount package with dimensions of 14x14 mm. The component is designed for industrial temperature ranges, supporting operation from -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent access to memory data from two separate ports simultaneously.
• Synchronous operation synchronized with a single clock signal for predictable timing performance.
• Standard SRAM technology providing volatile data retention without requiring refresh cycles.

Memory IC Applications

• Data buffering in high-speed digital signal processing systems
• Cache memory implementation in embedded microcontroller architectures
• FIFO buffer applications in telecommunications equipment

Memory IC Procurement Notes

Verify the specific speed grade suffix against the original design requirements, as variations exist within the 709269 series. Confirm RoHS compliance status, as older production batches may not meet current environmental directives. Check for end-of-life notices or obsolescence warnings from Renesas, as this component family may have limited long-term availability. Ensure the 100-TQFP footprint matches the PCB layout specifications exactly.

Memory IC Selection Notes

Select this component when simultaneous read/write access from two distinct masters is required. The 16-bit word width suits applications needing wide data buses without external multiplexing. Consider the synchronous interface timing constraints relative to the system clock speed. Evaluate the thermal dissipation capabilities of the TQFP package for the intended operating environment.

Memory IC Part Context

This part belongs to the Renesas 709269/709279 series of dual-port SRAMs. These devices are engineered for applications requiring high-bandwidth data sharing between processors or peripherals. The series offers various speed grades and capacities, with the 709269S7PFG representing a specific configuration optimized for standard industrial voltage levels and moderate access speeds.

Memory IC Replacement Considerations

Direct pin-to-pin replacements within the same series include other speed variants such as 709269S7PF or 709269S10PF, provided the access time meets system requirements. Cross-referencing with IDT or Cypress equivalents requires careful verification of pinout compatibility and electrical characteristics.
