CY7C4225-25JC

FIFOs Memory Overview

The CY7C4225-25JC is a synchronous FIFO memory integrated circuit manufactured by Cypress Semiconductor Corp. It features an organization of 1K x 18 bits, providing a total storage capacity of 18 kilobits. The device operates with a cycle time of 25 nanoseconds and supports a maximum data rate of 40 MHz. It functions within a supply voltage range of 3.0V to 3.6V and is designed for surface-mount installation in a 64-pin Thin Quad Flat Pack (TQFP) package. The component supports unidirectional bus directionality and includes programmable flags for status indication.

FIFOs Memory Feature Summary

• Supports high-speed synchronous data buffering with a 40 MHz clock frequency capability
• Includes programmable full and empty flags for precise buffer level monitoring
• Features retransmit capability to ensure data integrity during read operations

FIFOs Memory Applications

• High-speed data buffering between asynchronous system domains
• Clock domain crossing interfaces in digital signal processing systems
• Data acquisition systems requiring temporary storage before processing

FIFOs Memory Procurement Notes

Verify the specific suffix designation against official Cypress documentation to confirm pinout compatibility and electrical characteristics. Ensure the procurement source provides valid traceability for this legacy component. Confirm RoHS compliance status as original specifications may indicate non-compliance depending on the manufacturing date code. Validate package dimensions against the 64-TQFP standard prior to PCB layout finalization.

FIFOs Memory Selection Notes

Select this component when a 1K x 18 word depth is required for synchronous FIFO applications. The 25ns cycle time suits moderate-speed interface requirements. Consider the 3.3V operating voltage range for compatibility with low-voltage logic families. Evaluate the 64-pin TQFP package constraints against available board space and thermal management capabilities.

FIFOs Memory Part Context

This part belongs to the CY7C4225 family of low-voltage synchronous FIFOs from Cypress Semiconductor. The family offers various depths including 512x18, 1Kx18, 2Kx18, and 4Kx18 configurations. These devices are designed for high-performance data buffering in communication and computing systems, utilizing CMOS technology for low power consumption and high speed.

FIFOs Memory Replacement Considerations

Check for direct cross-reference equivalents such as the CY7C4225V-25JC variant which may offer lead-free packaging. Verify functional compatibility with other 1Kx18 synchronous FIFOs from different manufacturers if Cypress parts are unavailable.
