• Interface bridging in digital signal processing systems
• Data buffering in communication protocol converters
• Temporary storage in high-speed microcontroller interfaces

FIFOs Memory Procurement Notes

Verify the specific suffix JCT corresponds to the 32-PLCC package variant when sourcing. Confirm RoHS compliance status as older Cypress batches may not meet current environmental standards. Check manufacturer documentation for lead-free plating specifications if required by assembly processes. Ensure compatibility with 5V logic levels given the specified operating voltage range. Validate that the 10ns access time meets system timing requirements.

FIFOs Memory Selection Notes

Select this component when a 2K x 9 depth is required for synchronous buffering applications. Consider the 66.7MHz speed rating against system clock frequencies to ensure adequate throughput. Evaluate the 35mA power consumption against thermal constraints in dense PCB layouts. Compare the PLCC package dimensions against available board space. Verify that unidirectional data flow aligns with the intended data path architecture.

FIFOs Memory Part Context

This part belongs to the CY7C4231 series of low-voltage synchronous FIFOs from Cypress Semiconductor. The series offers various depths including 64, 256, 512, 1K, 2K, 4K, and 8K configurations. These devices are designed for high-performance data buffering in embedded systems. The CY7C4231 specifically targets applications requiring moderate depth with fast access times. It represents a standard solution for 9-bit wide data paths in legacy industrial designs.

FIFOs Memory Replacement Considerations

Direct substitutes include other CY7C4231 variants with different speed grades or packages, such as CY7C4231-25JCT. Cross-referencing with Infineon's current portfolio is recommended as Cypress was acquired. Verify pin compatibility and electrical characteristics before substituting with generic FIFO equivalents.
