CY7C4245-15ASXC

FIFOs Memory Overview

The CY7C4245-15ASXC is a 4K x 18 synchronous FIFO memory manufactured by Infineon Technologies. It features an 18-bit data bus width and supports independent read and write clocks for asynchronous operation. The device operates at a maximum frequency of 66.7 MHz with a 10 ns access time. It utilizes a 64-pin TQFP package and functions within a 4.5 V to 5.5 V supply range.

FIFOs Memory Feature Summary

• Supports fully asynchronous and simultaneous read and write operations using independent clock domains.
• Includes programmable Almost Full and Almost Empty status flags for precise buffer management.
• Enables depth expansion through cascade inputs and outputs to increase buffering capacity.
• Features a retransmit function to facilitate packet data acknowledgment and error recovery.

FIFOs Memory Applications

• High-speed data acquisition systems
• Multiprocessor interface buffering
• Communications data buffering

FIFOs Memory Procurement Notes

Verify the specific suffix 'ASXC' against official documentation, as standard datasheets list 'AXC'. Confirm availability status, as this component may be discontinued or subject to limited supply constraints. Ensure compatibility with existing system voltage levels and timing requirements before procurement.

FIFOs Memory Selection Notes

Select this component when an 18-bit wide synchronous FIFO with 4K depth is required. It is suitable for applications needing independent read/write clocks and programmable flag thresholds. Consider the 64-pin TQFP package constraints and verify that the 66.7 MHz speed meets system performance needs.

FIFOs Memory Part Context

This part belongs to the CY7C42X5 family of high-speed, low-power synchronous FIFOs. The family includes variants with densities ranging from 64x18 to 4Kx18. These devices are pin-compatible across the series and are designed for use in digital signal processing and communication interfaces requiring reliable data buffering.

FIFOs Memory Replacement Considerations

Check for direct substitutes within the CY7C42X5 family or IDT722X5 equivalents. Verify pinout and electrical specifications match exactly. No public confirmed substitute part numbers are listed in the provided source material.
