FIFOs Memory Procurement Notes

Verify the manufacturer designation matches Quality Semiconductor, Inc., as this component may be sourced from authorized distributors or surplus channels. Confirm the package type is strictly 132-QFP and check RoHS compliance status if required for specific manufacturing standards. Ensure the datasheet corresponds to the 20ns speed grade indicated by the suffix. Cross-reference part numbers carefully to avoid confusion with similar capacity devices.

FIFOs Memory Selection Notes

Select this component when a wide 36-bit data path is required for synchronous FIFO operations. The 20ns access time suits moderate-to-high speed logic applications. Consider the 132-pin QFP package constraints regarding PCB space and thermal management. Verify that the bi-directional feature aligns with the system's data flow requirements. Ensure compatibility with the target voltage levels and logic families used in the design.

FIFOs Memory Part Context

This part belongs to the QS725420 series of synchronous FIFOs. It is designed for applications requiring reliable data storage and retrieval with predictable timing characteristics. The 512x36 configuration provides a balance between depth and width for specialized data handling tasks. It represents a standard solution for managing data bursts in complex digital systems.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible substitutes within the same family, such as other speed grades of the QS725420 series. Verify electrical parameters like access time and operating voltage before substitution. Consult official replacement guides from Quality Semiconductor for validated alternatives.
