CY7C460-40JI

FIFOs Memory Overview

The CY7C460-40JI is an asynchronous FIFO memory integrated circuit manufactured by Cypress Semiconductor Corp. It features a storage capacity of 8K words by 9 bits, providing a total memory density of 72 kilobits. The device supports a maximum clock frequency of 20 MHz with a longest access time of 40 nanoseconds. It operates within a temperature range of -55°C to 125°C and utilizes CMOS technology. The component is housed in a 28-pin Ceramic Dual In-Line Package (CDIP) with side brazed construction.

FIFOs Memory Feature Summary

• Asynchronous operation mode for flexible data transfer between independent clock domains
• Retransmit capability to manage data flow control
• Industrial temperature range support for harsh environments

FIFOs Memory Applications

• Data buffering in high-speed digital signal processing systems
• Interface bridging between components operating at different clock speeds
• Temporary storage in telecommunications equipment requiring wide temperature tolerance

FIFOs Memory Procurement Notes

Verify the package type matches the required CDIP-28 specification. Confirm the suffix indicates the correct temperature grade for industrial applications. Check RoHS compliance status as older Cypress parts may not meet current environmental standards. Ensure the supplier provides valid traceability documentation for ceramic packages.

FIFOs Memory Selection Notes

Select this part when asynchronous FIFO functionality is required with 8Kx9 depth. Consider the 40ns access speed against system timing requirements. Evaluate the 28-pin CDIP package constraints for PCB layout. Compare power consumption specifications if thermal management is critical in the design.

FIFOs Memory Part Context

This component belongs to the CY7C460 family of asynchronous FIFOs from Cypress Semiconductor. It shares functional similarities with other members in the series but differs in speed grades and packaging options. The family is designed for general-purpose buffering applications in embedded systems and industrial controls.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible replacements within the CY7C460 series with different speed grades. Verify equivalent offerings from other manufacturers supporting 8Kx9 asynchronous FIFO architecture in ceramic DIP packages.
