CY7C4215-15AXI

FIFOs Memory Overview

The CY7C4215-15AXI is a 512 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 clock frequency of 66.7 MHz with a minimum cycle time of 15 ns. It includes programmable Almost Full and Almost Empty flags, retransmit functionality, and depth expansion capabilities via cascade pins.

FIFOs Memory Feature Summary

• Supports fully asynchronous and simultaneous read and write operations using independent clocks.
• Provides programmable status flags for Almost Full and Almost Empty conditions.
• Enables depth expansion through dedicated cascade input and output pins.
• Includes a retransmit function to facilitate packet data acknowledgment.

FIFOs Memory Applications

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

FIFOs Memory Procurement Notes

Verify the specific suffix AXI against official documentation to confirm package type and temperature range. Confirm current availability status as this component series may be subject to discontinuation notices. Ensure compatibility with existing system voltage levels and timing requirements before procurement.

FIFOs Memory Selection Notes

Select this model when a 512-word depth with 18-bit word width is required. Choose the -15 speed grade for applications needing up to 66.7 MHz operation. Consider width or depth expansion options if larger buffer capacities are needed beyond the single-device limit.

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 64 to 4K words. All members share pin and functional compatibility, allowing for flexible design scaling within the same product line.

FIFOs Memory Replacement Considerations

The CY7C4215 is functionally compatible with the IDT72215. Verify pinout and electrical specifications against the original design requirements when substituting with equivalent parts from other manufacturers.
