CY7C4245V-25ASXCT

FIFOs Memory Overview

The CY7C4245V-25ASXCT is a low-voltage synchronous FIFO memory with a density of 4K x 18 bits. It operates at a maximum frequency of 40 MHz with a minimum cycle time of 25 ns. The device supports 3.3V operation and features 5V tolerant inputs. It includes programmable Almost Empty and Almost Full flags, retransmit functionality, and independent read/write clocks.

FIFOs Memory Feature Summary

• Supports fully asynchronous and simultaneous read and write operations using independent clock domains.
• Provides five status flags including Empty, Full, Half Full, and two programmable flags for buffer management.
• Enables depth expansion through cascade input and output pins to increase buffering capacity beyond single-device limits.

FIFOs Memory Applications

• High-speed data acquisition systems requiring temporary storage.
• Multiprocessor interfaces needing reliable data handshaking.
• Communications buffering for packet transfer applications.

FIFOs Memory Procurement Notes

Verify the specific suffix 'ASXCT' against official Infineon or Cypress ordering guides to confirm package type and tape/reel specifications. Ensure the component matches the commercial temperature range and voltage requirements for your design.

FIFOs Memory Selection Notes

Select this model when an 18-bit wide interface is required with a depth of 4096 words. The 25 ns speed grade offers a balance between performance and power consumption suitable for general-purpose buffering tasks in 3.3V logic environments.

FIFOs Memory Part Context

This component belongs to the CY7C42X5V family of low-voltage synchronous FIFOs. The family ranges from 64x18 to 4Kx18 densities, sharing common control logic and pinouts while differing in memory array size and default flag offsets.

FIFOs Memory Replacement Considerations

Check for CY7C4245V-25AXC or CY7C4245V-25ASC as potential pin-compatible alternatives within the same series. Verify that any substitute maintains the 4K x 18 organization and 25 ns cycle time specifications.
