CY7C4221-25JC

FIFOs Memory Overview

The CY7C4221-25JC is a synchronous FIFO memory device manufactured by Cypress Semiconductor Corp. It features a memory organization of 1K x 9, providing a total density of 9216 bits. The component operates with a cycle time of 25 ns and an access time of 15 ns. It utilizes CMOS technology and is housed in a 32-pin Plastic Quad Flatpack (PQCC) package, also identified as LCC-32. The device supports three-state outputs and functions within a standard voltage range typical for its series.

FIFOs Memory Feature Summary

• Synchronous operation mode for precise data timing control
• Three-state output capability for bus sharing
• CMOS technology construction

FIFOs Memory Applications

• Data buffering between asynchronous systems
• Level translation in digital interfaces
• Temporary storage in high-speed data acquisition

FIFOs Memory Procurement Notes

Verify the specific suffix 'JC' against official Cypress documentation to confirm package type and temperature rating. Ensure compatibility with existing board layouts for the 32-pin PQCC form factor. Cross-reference manufacturer datasheets for electrical characteristics rather than relying on distributor summaries.

FIFOs Memory Selection Notes

Select this part when a 1Kx9 synchronous FIFO is required with a 25ns cycle time. Consider the 32-pin plastic quad flatpack package constraints. Verify that the synchronous interface aligns with the system clock requirements compared to asynchronous alternatives.

FIFOs Memory Part Context

This component belongs to the CY7C4221 family of synchronous FIFOs from Cypress. These devices are designed for high-performance data buffering applications. The family typically offers various speed grades and package options to suit different system integration needs.

FIFOs Memory Replacement Considerations

Check for CY7C4221V variants or other speed grades within the same family. Verify pinout compatibility before substituting with similar synchronous FIFOs from other manufacturers.
