CY7C4245-10AXC

FIFOs Memory Overview

The CY7C4245-10AXC is a 4K x 18 synchronous FIFO memory manufactured by Cypress Semiconductor. It features an 18-bit data width and supports high-speed operation with a maximum frequency of 100 MHz and a minimum cycle time of 10 ns. The device utilizes CMOS technology for low power consumption, offering independent read and write clocks. It includes programmable status flags and expansion capabilities for system integration.

FIFOs Memory Feature Summary

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

FIFOs Memory Applications

• High-speed data acquisition systems requiring temporary storage.
• Multiprocessor interfaces for efficient data exchange between processors.
• Communications buffering in network equipment and signal processing chains.

FIFOs Memory Procurement Notes

Verify the specific suffix '10AXC' against official Cypress documentation to confirm package type and temperature range. Ensure compatibility with existing design constraints regarding pinout and electrical specifications before procurement.

FIFOs Memory Selection Notes

Select this component when an 18-bit wide synchronous FIFO with 4K depth is required. Consider the 10 ns cycle time for high-frequency applications. Evaluate expansion needs to determine if cascading multiple units is necessary for larger buffers.
