QS7201-35JR

FIFOs Memory Overview

The QS7201-35JR is an asynchronous FIFO memory device manufactured by Quality Semiconductor Inc. It features a memory organization of 512 words by 9 bits, providing a total density of 4608 bits. The component supports a maximum access time of 35 nanoseconds with a cycle time of 50 nanoseconds. It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes CMOS technology. The device is housed in a 32-pin plastic quad flat package (PQCC32) with parallel data interfaces and three-state outputs.

FIFOs Memory Feature Summary

• Asynchronous operation mode for independent read and write clock domains
• CMOS technology ensuring low power consumption and high noise immunity
• Three-state outputs for easy bus interfacing and system integration

FIFOs Memory Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging between different speed logic families
• Temporary storage in digital signal processing systems

FIFOs Memory Procurement Notes

Verify the specific suffix 'JR' confirms the 35ns speed grade and plastic package variant against the official datasheet. Ensure compatibility with 5V logic levels and check for any lead-free or RoHS compliance certifications required for your assembly process. Confirm pinout alignment with existing PCB footprints before procurement.

FIFOs Memory Selection Notes

Select this part when a 512x9 depth is required with 35ns latency. Compare against the QS7201-50JR if slower speeds are acceptable for cost reduction. Consider the QS7201-80JR for applications prioritizing lower cost over speed. Ensure the asynchronous nature fits the system timing requirements compared to synchronous alternatives.

FIFOs Memory Part Context

This component belongs to the QS7201 series of asynchronous FIFOs from Quality Semiconductor. The series offers various speed grades and package options to suit different performance needs. The 35ns variant balances speed and power for general-purpose digital buffering tasks.

FIFOs Memory Replacement Considerations

Direct substitutes include other QS7201 variants such as the QS7201-50JR or QS7201-80JR, provided the speed requirements allow for slower performance. Verify pin compatibility and electrical specifications before substitution.
