CY7C472-15JC

FIFOs Memory Overview

The CY7C472-15JC is an asynchronous FIFO memory integrated circuit manufactured by Cypress Semiconductor Corp. It features a storage capacity of 16K x 9 bits and supports uni-directional data flow. The device operates at a maximum data rate of 33.3MHz with an access time of 15ns. It is housed in a 32-LCC (J-Lead) package, also referred to as 32-PLCC, measuring 13.97x11.43mm. The component is designed for surface mount installation and functions within a standard voltage range.

FIFOs Memory Feature Summary

• Asynchronous operation for independent read and write clock domains
• Uni-directional data transfer capability
• Programmable full and empty flag outputs

FIFOs Memory Applications

• Data buffering between asynchronous systems
• Level shifting between different voltage domains
• Clock domain crossing interfaces

FIFOs Memory Procurement Notes

Verify the specific suffix '15JC' against official Cypress documentation to confirm pinout compatibility and electrical characteristics. Confirm RoHS status as historical data may vary. Check current product lifecycle status, as this part may be discontinued or superseded by newer generations. Ensure the 32-LCC package dimensions match your PCB footprint requirements before ordering.

FIFOs Memory Selection Notes

Select this component when asynchronous FIFO functionality is required for 9-bit wide data paths. The 16K depth provides substantial buffering for burst data transfers. Consider the 15ns access time relative to system clock speeds. Evaluate the 32-LCC package for suitable surface mount assembly processes. Compare against synchronous alternatives if clock domain synchronization is preferred over asynchronous buffering.

FIFOs Memory Part Context

This part belongs to the CY7C4xx series of FIFO memories from Cypress Semiconductor. These devices are designed for high-performance data buffering applications. The series typically includes various capacities and speeds. The CY7C472 specifically offers 16K x 9 configuration. It is part of Cypress's legacy memory portfolio, now often managed under Infineon Technologies following acquisitions.

FIFOs Memory Replacement Considerations

Check for CY7C472 variants with different speed grades or packages. Verify cross-compatibility with other 16K x 9 asynchronous FIFOs from Cypress or Infineon. Ensure pin-to-pin compatibility if substituting directly.
