QS7202-50P

FIFOs Memory Overview

The QS7202-50P is an asynchronous FIFO memory device manufactured by Quality Semiconductor. It features a memory configuration of 1K x 9 bits, providing a total storage capacity of 9K bits. The component supports a maximum data rate of 15MHz with a typical access time of 50ns. Designed for through-hole mounting, it utilizes a bulk packaging format. This integrated circuit serves as a buffer for data transfer between systems operating at different clock speeds.

FIFOs Memory Feature Summary

• Asynchronous operation allows independent read and write clock domains
• Provides 9K bits of temporary data storage via 1K x 9 architecture
• Supports high-speed data buffering with 50ns access characteristics

FIFOs Memory Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging between systems with mismatched clock frequencies
• Temporary storage in digital signal processing chains

FIFOs Memory Procurement Notes

Verify the specific suffix 'P' indicates the package type and pinout configuration required for your design. Confirm RoHS compliance status if environmental regulations apply to your assembly process. Check product status as obsolete listings may indicate limited availability or end-of-life conditions from the manufacturer.

FIFOs Memory Selection Notes

Select this component when an asynchronous interface is required for 9-bit wide data paths. Ensure the 50ns speed grade meets the timing requirements of your system's slowest clock domain. Verify that the through-hole mounting style aligns with your PCB manufacturing capabilities and mechanical constraints.

FIFOs Memory Part Context

Quality Semiconductor was acquired by Microchip Technology. The QS7202 series represents a family of asynchronous FIFOs. The -50P variant specifically denotes the 50ns speed grade and plastic DIP package. Other variants like -80JR offer different speed and package options within the same functional family.

FIFOs Memory Replacement Considerations

Compatible substitutes include other 1Kx9 asynchronous FIFOs with similar access times. Verify pin compatibility before replacing. Cross-reference with Microchip's current FIFO portfolio for modern equivalents if new production is required.
