CY7C429-65AC

FIFOs Memory Overview

The CY7C429-65AC is an asynchronous FIFO memory device manufactured by Cypress Semiconductor Corp. It features a memory organization of 2K x 9 bits, providing a total capacity of 18 kilobits. The component supports a maximum access time of 65 nanoseconds and operates at a clock frequency of up to 12.5 MHz. It utilizes CMOS technology and is housed in a 32-pin TQFP package measuring 7x7 mm. The device includes three-state outputs and functions as a uni-directional buffer suitable for data synchronization applications.

FIFOs Memory Feature Summary

• Asynchronous operation mode for independent read and write clocks
• Uni-directional data flow architecture
• Three-state output capability for bus interfacing

FIFOs Memory Applications

• Data buffering between different clock domains
• Interface bridging in digital communication systems
• Temporary storage in microprocessor-based designs

FIFOs Memory Procurement Notes

Verify the specific suffix AC against official Cypress documentation to confirm pinout compatibility and electrical characteristics. Ensure the 32-TQFP package matches your PCB footprint requirements. Confirm RoHS compliance status with the supplier if environmental regulations apply to your manufacturing process.

FIFOs Memory Selection Notes

Select this component when an asynchronous interface is required for 9-bit wide data paths. The 65ns speed grade offers a balance between performance and power consumption for general-purpose buffering tasks. Consider the 2K depth sufficient for your burst size requirements before finalizing the design.

FIFOs Memory Part Context

This part belongs to the CY7C429 family of asynchronous FIFOs, which also includes variants with different depths such as 256, 512, 1K, and 4K configurations. The family shares common architectural features but varies in memory density and package options to suit diverse system integration needs.

FIFOs Memory Replacement Considerations

Check for CY7C429-65JI or CY7C429-65VC if alternative packages are needed. Verify that substitute parts maintain the same 2Kx9 organization and 65ns access time specifications to ensure functional equivalence in existing designs.
