CY7C419-15VC

Overview

The CY7C419-15VC is an asynchronous FIFO memory IC manufactured by Cypress Semiconductor Corp. It features a storage capacity of 2.25K bits, organized as 256 words by 9 bits. The device supports a data rate of 50MHz with a maximum access time of 15ns. It operates on a single 4.5V to 5.5V power supply and functions within a commercial temperature range of 0°C to 70°C. The component utilizes a 32-pin PLCC surface-mount package.

Feature Summary

• Asynchronous FIFO architecture for buffering data between different clock domains
• Supports unidirectional bus direction for dedicated input or output operations
• Includes programmable flags to indicate full, empty, or threshold conditions

Applications

• Data buffering in high-speed serial communication interfaces
• Clock domain crossing synchronization in digital logic systems
• Temporary storage in embedded controller data acquisition paths

Procurement Notes

Verify the specific suffix 'VC' against official Cypress documentation to confirm pinout compatibility and voltage tolerances. Confirm RoHS compliance status as historical records vary. Ensure the 32-PLCC package matches the target PCB footprint. Validate that the 15ns access time meets system timing requirements before integration.

Selection Notes

Select this component when a small, fast asynchronous buffer is required for 9-bit wide data paths. The 256-word depth suits applications needing moderate latency tolerance. Compare against synchronous alternatives if deterministic timing across clock edges is critical. Verify that the 5V logic levels align with the surrounding circuitry interface standards.
