CY7C4255V-25ASC

FIFOs Memory Overview

The CY7C4255V-25ASC is a synchronous FIFO memory device manufactured by Cypress Semiconductor Corp. It features an 8K x 18 bit storage organization, providing a total capacity of 144 kilobits. The component supports data rates up to 40MHz with a maximum access time of 15ns. It operates within a voltage range of 3V to 3.6V and is housed in a 64-TQFP package measuring 10x10mm. Designed for industrial applications, it functions reliably between 0°C and 70°C.

FIFOs Memory Feature Summary

• Supports depth expansion capabilities for flexible system integration
• Includes width expansion functionality to adapt to varying bus widths
• Features retransmit capability to ensure data integrity during transfer

FIFOs Memory Applications

• High-speed data buffering in communication systems
• Clock domain crossing interfaces in digital logic designs
• Data acquisition systems requiring precise timing synchronization

FIFOs Memory Procurement Notes

Verify the specific suffix 'V' indicates voltage or variant specifications as per official datasheets. Confirm RoHS compliance status, as some Cypress variants may not meet current environmental standards. Ensure the 64-TQFP package dimensions match your PCB footprint requirements. Check for lead-free plating options if required by assembly processes.

FIFOs Memory Selection Notes

Select this component when a synchronous FIFO with 18-bit word width and 8K depth is required. The 15ns access time suits moderate-speed applications up to 40MHz. Consider the 3V-3.6V supply range compatibility with your system's power rails. Verify that the TQFP package fits your board space constraints compared to other available packages.

FIFOs Memory Part Context

This part belongs to the CY7C4255 series of synchronous FIFOs from Cypress. The series offers various speed grades and configurations. The CY7C4255V-25ASC specifically denotes the 25ns (15ns access) speed grade within the 3V family. It shares architectural similarities with other members like the CY7C4255V-15ASC but differs in performance metrics.

FIFOs Memory Replacement Considerations

Check for direct substitutes within the CY7C4255 series such as different speed grades. Verify pin-to-pin compatibility before replacing. Ensure the replacement maintains the same 18-bit width and 8K depth specifications.
