CY7C421-15AXC

FIFOs Memory Overview

The CY7C421-15AXC is a 512 x 9 asynchronous FIFO memory component manufactured by Infineon Technologies. It features an independent read and write clock architecture with a maximum access time of 15 ns. The device operates on a single 5 V power supply within the commercial temperature range of 0 °C to +70 °C. It utilizes a 32-pin TQFP package and supports TTL-compatible logic levels.

FIFOs Memory Feature Summary

• Supports asynchronous read and write operations at speeds up to 50 MHz
• Includes Full, Empty, and Half Full status flags for flow control
• Enables unlimited expansion in depth and width via dedicated pins
• Features retransmit capability for data packet handling

FIFOs Memory Applications

• Buffering data between components operating at different clock rates
• Data storage in telecommunications equipment
• Interface bridging in industrial automation systems

FIFOs Memory Procurement Notes

Verify the specific ordering code suffix against official documentation to confirm package type and speed grade. Confirm current availability status as legacy products may be discontinued or subject to limited supply constraints.

FIFOs Memory Selection Notes

Select this component when a small-depth asynchronous buffer is required. Ensure the system design accommodates the 5 V supply voltage and 32-pin TQFP footprint. Verify that the 15 ns access time meets the timing requirements of the target application interface.

FIFOs Memory Part Context

This part belongs to the CY7C421 family of asynchronous FIFO memories. It is functionally equivalent to industry-standard parts such as the IDT7201 and AM7201. The series provides various speed grades and package options to suit different integration needs.

FIFOs Memory Replacement Considerations

The CY7C421-15AXC is pin compatible and functionally equivalent to the IDT7201 and AM7201. Verify electrical characteristics and package dimensions before substituting.
