CY7C425-40PC

Overview

The CY7C425-40PC is a synchronous FIFO memory component manufactured by Cypress Semiconductor Corp. It features a storage capacity of 16K x 9 bits and operates with a maximum data rate of 20MHz. The device has a typical access time of 40ns and supports unidirectional bus direction. It is housed in a 28-PDIP package and requires a supply voltage between 4.5 V and 5.5 V.

Feature Summary

• Synchronous first-in, first-out memory architecture for reliable data buffering
• Unidirectional data flow capability for specific interface requirements
• Standard parallel interface configuration within a dual in-line package

Applications

• Data buffering in high-speed digital systems
• Interface bridging between asynchronous logic blocks
• Temporary storage in communication protocols

Procurement Notes

Verify the exact pinout and electrical characteristics against the official Cypress datasheet before integration. Confirm that the 28-PDIP package dimensions match your PCB footprint. Ensure the operating voltage range aligns with your system power supply. Check for RoHS compliance status if required by your manufacturing standards. Validate the supplier's authenticity to avoid counterfeit components.

Selection Notes

Select this part when a synchronous FIFO with 16K depth and 9-bit width is required. The 40ns access time suits moderate-speed applications. Consider the PDIP package for prototyping or through-hole assembly needs. Compare against other CY7C42x series variants if different depths or speeds are needed. Ensure the unidirectional nature fits your data path design.

Part Context

This component belongs to the CY7C42x family of FIFO memories from Cypress Semiconductor. These devices are designed for general-purpose data buffering. The CY7C425 variant specifically offers 16K x 9 organization. Other members in the series may offer different capacities or speeds. The family is known for standard CMOS technology.

Replacement Considerations

Check for direct substitutes within the CY7C425 series with different speed grades. Verify compatibility with other 28-pin DIP FIFOs if pinouts differ. Ensure functional equivalence in terms of synchronization method and data width.
