QS7202-20JR

FIFOs Memory Overview

The QS7202-20JR is an asynchronous FIFO memory component manufactured by Quality Semiconductor. It features a memory organization of 1K x 9 bits, providing a total capacity of 9 kilobits. The device supports a maximum clock frequency of 33 MHz with a typical access time of 20 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes CMOS technology. The component is available in a surface-mount package suitable for automated assembly processes.

FIFOs Memory Feature Summary

• Asynchronous operation allows independent read and write clock domains for flexible data buffering.

FIFOs Memory Applications

• Data buffering between systems operating at different clock speeds
• Interface bridging in digital communication links
• Temporary storage in high-speed data acquisition systems

FIFOs Memory Procurement Notes

Verify the specific suffix 'JR' indicates the correct surface-mount package variant when sourcing. Confirm RoHS3 compliance status if environmental regulations apply to your manufacturing process. Ensure the supplier provides official datasheets matching the Quality Semiconductor part number to avoid counterfeit components. Check for lead-free certification documentation required for final assembly standards.

FIFOs Memory Selection Notes

Select this component when a 1K x 9 depth is required for asynchronous data buffering applications. The 20 ns access time suits moderate-speed digital interfaces. Consider the surface-mount packaging requirement for PCB layout compatibility. Verify that the 5V logic levels match the system's I/O voltage specifications before integration into the design.

FIFOs Memory Part Context

This part belongs to the QS7202 series of asynchronous FIFOs from Quality Semiconductor. The series typically offers various speed grades and organizational options. The QS7202-20JR specifically denotes the 20 ns speed grade within the 1K x 9 configuration family. Related parts may include faster access times or different word widths depending on system requirements.

FIFOs Memory Replacement Considerations

Direct substitutes must match the 1K x 9 organization, asynchronous interface, and 20 ns minimum access time. Verify pinout compatibility for the specific surface-mount package type. Ensure voltage tolerance ranges align with the existing 4.5V to 5.5V supply rails. Cross-reference with other manufacturers offering equivalent CMOS asynchronous FIFO devices.
