CY7C4245-15AXC

FIFOs Memory Overview

The CY7C4245-15AXC is a 4K x 18 synchronous FIFO memory fabricated in CMOS technology. It features independent read and write clocks, allowing for asynchronous operation modes. The device includes programmable Almost Full and Almost Empty flags, retransmit functionality, and depth/width expansion capabilities. It operates at a maximum frequency of 66.7 MHz with a cycle time of 15 ns. Available in 64-pin TQFP and 68-pin PLCC packages, it supports TTL-compatible inputs and provides low power consumption.

FIFOs Memory Feature Summary

• Supports simultaneous independent read and write operations using separate clock domains.
• Features programmable status flags for precise buffer level monitoring.
• Includes retransmit function to facilitate packet data acknowledgment and re-sending.
• Enables system scalability through width and depth expansion configurations.

FIFOs Memory Applications

• High-speed data acquisition systems requiring buffering between disparate clock domains.
• Multiprocessor interfaces needing reliable data transfer synchronization.
• Communications equipment requiring packet buffering and flow control.

FIFOs Memory Procurement Notes

Verify the specific suffix 'AXC' against official Cypress/Infineon documentation to confirm package type (TQFP vs PLCC) and temperature grade. Ensure the ordering code matches the required speed grade (-15). Confirm RoHS compliance status if applicable to your manufacturing requirements.

FIFOs Memory Selection Notes

Select this component when an 18-bit wide, 4096-word deep synchronous FIFO is required. Choose the -15 speed grade for applications needing up to 66.7 MHz operation. Consider the TQFP or PLCC package based on PCB layout constraints. Verify that the voltage levels and interface requirements match the system design.

FIFOs Memory Part Context

This part belongs to the CY7C42X5 family of high-speed, low-power synchronous FIFOs. The family includes variants with different depths ranging from 64 to 4K words. All members share pin compatibility and functional similarities, differing primarily in storage capacity and available package options.

FIFOs Memory Replacement Considerations

Check for direct substitutes within the CY7C42X5 series or IDT722X5 compatible devices. Verify pinout and electrical specifications before substitution. No specific public substitute part numbers are confirmed in the provided source material.
