QS7202-50JR

FIFOs Memory Overview

The QS7202-50JR is an asynchronous FIFO memory IC manufactured by Quality Semiconductor. It features a 1K x 9-bit data width and a 50ns access time. The device provides high-speed data buffering capabilities for digital systems requiring rapid transfer and processing.

FIFOs Memory Feature Summary

• Asynchronous operation for flexible clock domain interfacing
• High-speed data buffering with 50ns access time
• 1K x 9-bit memory array configuration

FIFOs Memory Applications

• Data buffering in digital signal processing systems
• Interface bridging between different clock domains
• Temporary storage in high-speed data acquisition circuits

FIFOs Memory Procurement Notes

Verify the manufacturer designation as Quality Semiconductor, now part of Microchip Technology. Confirm the specific suffix '50JR' indicates the 50ns speed grade and package type. Request official datasheets to validate pinout compatibility and electrical specifications before integration into designs.

FIFOs Memory Selection Notes

Select this component when asynchronous FIFO functionality with a 9-bit word width is required. The 50ns access time suits moderate-speed applications. Ensure system voltage levels match the device specifications and that the physical package fits the PCB layout constraints.

FIFOs Memory Part Context

This part belongs to the QS7202 series of asynchronous FIFOs from Quality Semiconductor. The series offers various speed grades and configurations for memory buffering needs. Quality Semiconductor was acquired by Microchip Technology, which continues to support these legacy logic components.

FIFOs Memory Replacement Considerations

The QS7202-80JR is a confirmed substitute within the same family, offering identical 1K x 9-bit architecture but with an 80ns access time. Verify timing requirements before substitution.
