QS7201-15V

FIFOs Memory Overview

The QS7201-15V is an asynchronous FIFO memory integrated circuit manufactured by Quality Semiconductor. It features a storage organization of 512 words by 9 bits, providing a total capacity of 4608 bits. The device supports a maximum clock frequency of 40 MHz with a typical access time of 15 ns. It operates on a single 5 V power supply and utilizes CMOS technology for low power consumption. The component is housed in a 28-pin PDIP package.

FIFOs Memory Feature Summary

• Asynchronous operation mode allows independent read and write clock domains
• CMOS technology ensures low power consumption and high noise immunity
• Standard 5 V logic compatibility for easy integration
• Dedicated full and empty status flags for flow control

FIFOs Memory Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging between systems with different clock speeds
• Temporary data storage in digital signal processing chains
• Level shifting applications between different voltage logic families

FIFOs Memory Procurement Notes

Verify the specific suffix 'V' indicates the correct package variant, typically plastic DIP, as opposed to other package options like J or P. Confirm RoHS compliance status as older datasheets may list non-compliance. Ensure the manufacturer is identified as Quality Semiconductor, distinct from IDT which produced similar QS7201 parts. Check for lead-free markings if required for modern assembly processes.

FIFOs Memory Selection Notes

Select this part when a 512x9 depth is required for asynchronous data buffering. The 15 ns access time suits moderate-speed digital interfaces. Compare against faster variants like the -12 version if higher throughput is needed, or slower versions if cost is the primary constraint. Ensure the 28-pin DIP package fits the target PCB layout constraints.

FIFOs Memory Part Context

The QS7201 series represents a family of asynchronous FIFOs designed for general-purpose data buffering. Variants such as QS7201-12 and QS7201-50 offer different speed grades while maintaining the same 512x9 architecture. This specific model balances speed and power for standard 5 V logic applications.

FIFOs Memory Replacement Considerations

QS7201-12V offers faster 12 ns access time with identical pinout and functionality. QS7201-50V provides slower 50 ns access but may be lower cost. Verify that substitute parts maintain the 512x9 organization and 28-pin DIP package.
