QS7201-10Q

FIFOs Memory Overview

The QS7201-10Q is an asynchronous FIFO memory device manufactured by Quality Semiconductor. It features a 512 x 9-bit organization, providing a total storage capacity of 4.5K bits. The component supports high-speed operation with a data rate of 66MHz and offers a fast access time of 10ns. It operates within a supply voltage range of 4.5V to 5.5V, with a maximum supply current of 60mA.

FIFOs Memory Feature Summary

• Asynchronous first-in-first-out memory architecture for independent read/write clock domains
• High-speed data transfer capability supporting 66MHz operation rates
• Fast 10ns access time for efficient signal buffering

FIFOs Memory Applications

• Buffering data between asynchronous digital systems
• Signal processing interfaces requiring independent clock domains
• Memory management in high-speed logic circuits

FIFOs Memory Procurement Notes

Verify the specific suffix '10Q' to confirm the 10ns speed grade and package type. Ensure compatibility with the required 4.5V to 5.5V supply voltage range. Confirm that the 60mA maximum supply current meets system power constraints. Check for RoHS compliance status if required by project specifications.

FIFOs Memory Selection Notes

Select this component when asynchronous buffering is required between different clock domains. The 512x9 bit depth suits moderate buffer sizes. The 10ns speed grade is suitable for applications up to 66MHz. Consider alternative speed grades like -35 or -50 if lower frequency operation allows for cost reduction.

FIFOs Memory Part Context

The QS7201 series comprises asynchronous FIFOs from Quality Semiconductor. Variants include QS7201-35 and QS7201-50, which offer slower access times. The base QS7201 model shares the same 512x9 architecture but differs in performance metrics based on the speed suffix.

FIFOs Memory Replacement Considerations

Compatible substitutes include QS7201-35Q and QS7201-50Q, which share the same pinout and memory organization but have slower access times. Verify that the reduced speed of these alternatives does not impact system timing requirements.
