CY7C429-65JC

Overview

The CY7C429-65JC is an asynchronous FIFO memory component manufactured by Cypress Semiconductor Corp. It features a storage organization of 2K words by 9 bits, providing a total memory density of 18 kilobits. The device supports a maximum access time of 65 nanoseconds with a cycle time of 80 nanoseconds. It operates using CMOS technology and utilizes a 32-pin Plastic Leaded Chip Carrier (PLCC) package. The component functions as a single-port buffer memory designed for high-speed data buffering applications.

Feature Summary

• Asynchronous first-in first-out buffer memory architecture
• Dual-ported RAM cell structure
• TTL compatible logic levels
• Retransmit capability in standalone configuration

Applications

• High-speed data buffering between asynchronous systems
• Data rate matching in communication interfaces
• Buffering in digital signal processing pipelines

Procurement Notes

Verify the specific suffix 'JC' against official Cypress documentation to confirm the exact package type and temperature range. Ensure compatibility with existing system voltage requirements and interface standards before procurement. Confirm RoHS compliance status if required by your manufacturing specifications.

Selection Notes

Select this component when a 2Kx9 asynchronous FIFO is required with a 65ns access speed. Consider the PLCC package availability and pinout compatibility with legacy designs. Evaluate expansion capabilities if wider or deeper memory buffers are needed in the final application design.

Part Context

This part belongs to the CY7C429 series of asynchronous FIFOs from Cypress Semiconductor. The series includes variants with different depths such as 256x9, 512x9, 1Kx9, and 4Kx9. These devices are designed to provide flexible buffering solutions with independent read and write clocks.
