CY7C4221V-15JC

FIFOs Memory Overview

The CY7C4221V-15JC is a synchronous FIFO memory device manufactured by Cypress Semiconductor Corp. It features a storage capacity of 8K x 9 bits, providing a total of 72 kilobits of data buffering. The component supports a maximum clock frequency of 66.7 MHz with an access time of 10 nanoseconds. It operates within a supply voltage range of 4.5 V to 5.5 V and draws a maximum supply current of 35 mA. The device is housed in a 32-pin PLCC package and is designed for surface mount installation.

FIFOs Memory Feature Summary

• Synchronous operation with unidirectional bus directionality
• Supports programmable full and empty flag outputs
• Capable of depth and width expansion for system integration

FIFOs Memory Applications

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

FIFOs Memory Procurement Notes

Verify the exact suffix against official Cypress documentation to confirm pinout compatibility and electrical specifications. Confirm RoHS compliance status as older revisions may not meet current environmental standards. Check for end-of-life notices or obsolescence warnings from Infineon Technologies, the successor manufacturer. Ensure the package type matches the target PCB footprint requirements before procurement.

FIFOs Memory Selection Notes

Select this component when a small, fast synchronous buffer is required for 9-bit wide data paths. Compare against the CY7C4231V for larger capacities or CY7C4211V for smaller depths. Ensure the 5V operating voltage aligns with the system power rails. Verify that the 32-PLCC package is suitable for the assembly process and available board space constraints.

FIFOs Memory Part Context

This part belongs to the CY7C42x1V family of low-voltage synchronous FIFOs. These devices are designed for high-performance applications requiring reliable data synchronization. The family shares common interface characteristics but varies in memory depth. Cypress Semiconductor was acquired by Infineon Technologies, which continues to support these legacy memory products.

FIFOs Memory Replacement Considerations

Check for CY7C4221V-15JXC as a potential variant with different packaging or temperature ratings. Verify cross-compatibility with other CY7C42x1V series parts if system flexibility is needed.
