CY7C4251-15JC

FIFOs Memory Overview

The CY7C4251-15JC is a synchronous FIFO memory device manufactured by Cypress Semiconductor Corp. It features a storage capacity of 36K bits, organized as 4K words by 9 bits. The component supports unidirectional data transfer with a maximum data rate of 66.7MHz and an access time of 10ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 35mA. The device is housed in a 32-PLCC package (11.43x13.97mm) designed for surface mount installation.

FIFOs Memory Feature Summary

• Synchronous operation with single-clock domain control for reliable data buffering
• Unidirectional bus architecture simplifies interface design for specific data flow paths
• Integrated programmable flags provide status monitoring without external logic

FIFOs Memory Applications

• High-speed data buffering between asynchronous system components
• Interface bridging in telecommunications equipment requiring precise timing
• Data acquisition systems needing temporary storage before processing

FIFOs Memory Procurement Notes

Verify the exact suffix against official Cypress documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status as older revisions may not meet current environmental standards. Check for obsolescence notices from the manufacturer or authorized distributors. Ensure the 32-PLCC package dimensions match the target PCB footprint requirements. Validate that the 4.5V to 5.5V operating range aligns with the system power supply specifications.

FIFOs Memory Selection Notes

Select this component when a synchronous FIFO with 4K x 9 organization is required. Consider the 10ns access time for high-speed applications. Verify compatibility with 5V logic levels. Evaluate the 32-PLCC package size against available board space. Compare performance metrics against alternative devices in the CY7C42xx series if different capacities are needed.

FIFOs Memory Part Context

This part belongs to the CY7C42xx family of synchronous FIFOs from Cypress Semiconductor. These devices are designed for high-performance data buffering applications. The family offers various configurations differing in depth, width, and speed grades. The CY7C4251 variant specifically provides 36K-bit capacity in a compact PLCC package suitable for dense circuit designs.

FIFOs Memory Replacement Considerations

Check for CY7C4251-15JXC as a potential equivalent with similar specifications. Verify pin-to-pin compatibility before substitution. Review datasheet differences regarding electrical parameters and package tolerances.
