CY7C43664-7AC

FIFOs Memory Overview

The CY7C43664-7AC is an asynchronous FIFO memory IC manufactured by Cypress Semiconductor Corp. It features a dual-port architecture with a memory size of 16K x 36 x 2 bits. The device supports bi-directional data transfer and operates at clock frequencies up to 133MHz, with an access time of 6ns. It is housed in a 128-TQFP package measuring 14x20 mm. The component functions within an operating temperature range of 0°C to 70°C and is classified as RoHS non-compliant.

FIFOs Memory Feature Summary

• Asynchronous dual-port operation for independent read and write clocks
• Bi-directional data flow capability between ports
• High-speed performance supporting 133MHz clock rates

FIFOs Memory Applications

• Data buffering in high-speed digital signal processing systems
• Clock domain crossing interfaces in communication equipment
• Temporary storage in computer peripheral controllers

FIFOs Memory Procurement Notes

Verify the specific suffix '7AC' against official Cypress or Infineon datasheets to confirm pinout and electrical characteristics match your design requirements. Confirm RoHS non-compliance status if environmental regulations apply to your assembly process. Ensure the 128-TQFP package dimensions align with your PCB footprint specifications before finalizing procurement orders.

FIFOs Memory Selection Notes

Select this component when asynchronous interface flexibility is required over synchronous alternatives. The 16K x 36 depth provides substantial buffering capacity for wide data buses. Consider the 6ns access time suitability for your system's timing constraints. Evaluate the TQFP package for thermal management needs in enclosed environments.

FIFOs Memory Part Context

This part belongs to the CY7C series of FIFO memories from Cypress Semiconductor, now part of Infineon Technologies. The series offers various configurations for different data widths and depths. The CY7C43664 variant specifically targets applications requiring high throughput and bidirectional data handling capabilities in industrial and commercial electronic systems.

FIFOs Memory Replacement Considerations

Check for CY7C43664AV-7AC as a potential alternative, noting it is specified as a synchronous FIFO rather than asynchronous. Verify compatibility regarding clocking schemes and interface protocols before substitution. Consult official cross-reference guides for exact functional equivalence.
