QS723621-25TF

FIFOs Memory Overview

The QS723621-25TF is a synchronous bidirectional first-in, first-out (FIFO) memory buffer manufactured by Quality Semiconductor. It features a memory organization of 2K words by 36 bits, providing a total capacity of 72 kilobits. The device operates with a maximum access time of 25 nanoseconds and supports a supply voltage range of 4.5V to 5.5V, with a nominal voltage of 5V. It is housed in a 144-pin Quad Flat Package (QFP) suitable for surface-mount technology.

FIFOs Memory Feature Summary

• Supports bidirectional data flow between two independent clock domains
• Provides high-speed synchronous buffering with 25ns access time
• Features a wide 36-bit data bus for efficient parallel data transfer

FIFOs Memory Applications

• Data buffering between asynchronous systems
• High-speed interface bridging in communication equipment
• Temporary storage in digital signal processing architectures

FIFOs Memory Procurement Notes

Verify the specific package variant, as the part number indicates a 144-QFP configuration. Confirm that the 25ns speed grade matches system timing requirements. Ensure the 5V logic level compatibility aligns with the target circuit design. Check for RoHS compliance status if environmental regulations apply to the manufacturing process.

FIFOs Memory Selection Notes

Select this component when a wide 36-bit data path is required for synchronous FIFO operations. The 25ns speed rating suits applications needing moderate-to-high throughput. Consider the 144-pin QFP footprint for PCB layout constraints. Verify power supply stability within the 4.5V to 5.5V range for reliable operation.

FIFOs Memory Part Context

This component belongs to the QS7236xx series of synchronous FIFOs from Quality Semiconductor. The series typically offers various data widths and speeds. The QS723621 variant specifically provides the 2Kx36 organization, distinguishing it from narrower or deeper memory configurations in the same product family.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible substitutes from Quality Semiconductor with identical 2Kx36 organization and 25ns speed. Verify functional equivalence for bidirectional control signals before substitution.
