QS7203-25V

FIFOs Memory Overview

The QS7203-25V is a 2K x 9 asynchronous FIFO memory device manufactured by Quality Semiconductor. It operates with a core voltage of 5.0 V and features a uni-directional architecture. The component provides an access time of 25 ns, supporting data transfer rates suitable for high-speed digital systems. It utilizes CMOS technology and is housed in a 28-pin SOJ package. The device is designed for applications requiring reliable buffer storage between asynchronous clock domains.

FIFOs Memory Feature Summary

• Asynchronous operation allows independent read and write clock domains
• Uni-directional data flow simplifies interface design
• CMOS technology ensures low power consumption
• Standard 5.0 V TTL-compatible I/O levels

FIFOs Memory Applications

• Buffering data streams between microprocessors and peripherals
• Synchronizing data transfers in communication interfaces
• Temporary storage in digital signal processing chains
• Level shifting between different voltage logic families

FIFOs Memory Procurement Notes

Verify the specific package variant (SOJ vs DIP) and temperature range against project requirements. Confirm end-of-life status or obsolescence notices from the manufacturer. Ensure compatibility with existing PCB footprints and soldering profiles. Check for alternative sources if primary supply is limited.

FIFOs Memory Selection Notes

Select this part when a 2K x 9 depth is required with 25 ns access speed. Consider the 5.0 V operating voltage constraint. Evaluate the physical size of the SOJ package against board space limitations. Compare performance metrics with newer asynchronous FIFO alternatives if available.

FIFOs Memory Part Context

This component belongs to the 7203 series of asynchronous FIFOs. It shares architectural similarities with other members like the 7203L25P but differs in package type and manufacturing process. The series is known for providing simple plug-and-play buffering solutions for legacy and industrial systems.

FIFOs Memory Replacement Considerations

Direct substitutes include the 7203-25V and similar 2Kx9 asynchronous FIFOs. Verify pinout compatibility before replacement. Check if updated versions offer improved access times or lower power consumption while maintaining functional equivalence.
