CY7C455-14JI

FIFOs Memory Overview

The CY7C455-14JI is an asynchronous FIFO memory IC manufactured by Cypress Semiconductor Corp. It features a memory organization of 512 x 18 bits and supports unidirectional data flow. The device operates with a maximum data rate of 71.4MHz and an access time of 10ns. It requires a supply voltage range of 4.5 V to 5.5 V. The component is housed in a 52-PLCC package measuring 19.13x19.13 mm.

FIFOs Memory Feature Summary

• Asynchronous operation for independent read and write clock domains
• Unidirectional data transfer capability
• High-speed buffering performance with 10ns access time

FIFOs Memory Applications

• Data buffering between different clock domains
• High-performance system interface synchronization
• Temporary storage in digital signal processing chains

FIFOs Memory Procurement Notes

Verify the specific suffix '14JI' against official Infineon or Cypress documentation to confirm pinout, speed grade, and environmental compliance status. Ensure the supplier provides valid traceability for this legacy part number. Confirm package integrity upon receipt as PLCC components may be subject to handling sensitivity during storage and transportation.

FIFOs Memory Selection Notes

Select this component when asynchronous decoupling between clock domains is required. The 512 x 18 depth suits moderate buffering needs. Verify that the 5V logic level compatibility matches the system design. Consider the 52-PLCC package constraints for PCB layout and thermal management requirements in the final application environment.

FIFOs Memory Part Context

This part belongs to the CY7C455 family of asynchronous FIFOs from Cypress Semiconductor, now part of Infineon Technologies. These devices are designed for high-speed data buffering applications where independent read and write clocks are necessary. The family typically offers various depths and widths to accommodate different system bandwidth requirements.

FIFOs Memory Replacement Considerations

Check for direct cross-references within the Infineon memory portfolio. Verify electrical compatibility and pinout alignment before substituting. No public confirmed substitute part numbers are identified in the provided source material.
