QS7201-20P

FIFOs Memory Overview

The QS7201-20P is an asynchronous FIFO memory device manufactured by Quality Semiconductor. It features a memory organization of 512 words by 9 bits, providing a total capacity of 4.5K bits. The component supports a maximum data rate of 33MHz with a specified access time of 20ns. It operates on a single 5V power supply and utilizes CMOS technology. The device includes three-state outputs for efficient bus interfacing.

FIFOs Memory Feature Summary

• Asynchronous operation allows independent read and write clock domains
• Three-state outputs facilitate connection to shared system buses
• CMOS construction ensures low power consumption during operation

FIFOs Memory Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging between systems operating at different clock speeds
• Temporary storage in high-speed digital signal processing chains

FIFOs Memory Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Ensure the source provides valid datasheets confirming the asynchronous nature and 5V logic levels. Cross-reference part numbers with authorized distributors to avoid obsolete or counterfeit components.

FIFOs Memory Selection Notes

Select this component when a small, fast asynchronous buffer is required for 9-bit wide data paths. Consider the 20ns access time for timing constraints relative to the system clock. Evaluate package availability if ceramic chip carrier form factors are acceptable for the target design environment.

FIFOs Memory Part Context

This part belongs to the QS7201 series of asynchronous FIFOs from Quality Semiconductor. The series offers various speed grades and organizations to suit different bandwidth requirements. These devices are designed for general-purpose data buffering applications in industrial and commercial electronic systems.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible substitutes within the same family, such as the QS7201-20PI or QS7201-20P6, noting that some variants may be marked obsolete. Verify functional equivalence before substituting with parts from other manufacturers.
