CY7C4205-10AXCT

FIFOs Memory Overview

The CY7C4205-10AXCT is a 256 x 18 synchronous FIFO memory manufactured by Infineon Technologies. It operates at a maximum frequency of 100 MHz with an 8 ns access time and supports simultaneous asynchronous read and write operations. The device features programmable Almost Full/Empty flags, retransmit capability, and independent clock inputs. It is available in 64-pin TQFP packages.

FIFOs Memory Feature Summary

• Supports fully asynchronous and simultaneous read/write operations with independent clocks
• Includes programmable Almost Full and Almost Empty status flags for precise buffer management
• Features a retransmit function to facilitate packet data acknowledgment and re-sending
• Enables depth expansion through cascade input/output pins for increased buffering capacity

FIFOs Memory Applications

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

FIFOs Memory Procurement Notes

Verify the specific suffix AXCT against official datasheets to confirm package type and temperature range. Ensure compatibility with existing system voltage levels and clock frequencies. Confirm availability status as product lifecycles may change. Cross-reference pinouts if replacing older components.

FIFOs Memory Selection Notes

Select this component for applications requiring high-speed buffering with flexible clocking options. Consider the 256-word depth and 18-bit width for specific data path requirements. Evaluate the need for programmable flags and retransmit features versus simpler FIFO alternatives.

FIFOs Memory Part Context

This part belongs to the CY7C42X5 family of synchronous FIFOs, which includes variants with different depths such as 64, 512, 1K, 2K, and 4K words. All members share compatible pinouts and functional architectures, allowing for scalable design implementations within the same ecosystem.

FIFOs Memory Replacement Considerations

The CY7C4205 is functionally compatible with IDT72205 devices. Verify pin-to-pin compatibility and electrical specifications before substitution.
