CY7C429-65JI

FIFOs Memory Overview

The CY7C429-65JI is an asynchronous FIFO memory device manufactured by Cypress Semiconductor Corp. It features a storage organization of 2K x 9 bits, providing a total memory density of 18,432 bits. The component supports a maximum access time of 65 ns and operates with a cycle time of 80 ns. It utilizes CMOS technology and is housed in a 32-pin Plastic Leaded Chip Carrier (PLCC) package. The device functions as a single-function unit with three-state outputs and is designed for asynchronous operation modes.

FIFOs Memory Feature Summary

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

FIFOs Memory Applications

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

FIFOs Memory Procurement Notes

Verify the specific suffix 'JI' against official Cypress documentation to confirm the exact package variant and temperature range. Ensure compatibility with existing board layouts for the 32-pin PLCC footprint. Confirm RoHS compliance status if required by current manufacturing standards, as older revisions may differ. Cross-reference pinouts with the official datasheet to prevent interface mismatches during integration.

FIFOs Memory Selection Notes

Select this component when an asynchronous FIFO with 2K x 9 depth is required. The 65 ns access time suits moderate-speed applications. Consider the PLCC package constraints for PCB design. Verify that the asynchronous nature aligns with the system clocking strategy. Compare against synchronous alternatives if deterministic timing is critical for the application.

FIFOs Memory Part Context

This part belongs to the CY7C429 series of asynchronous FIFO memories from Cypress. The series includes variants with different depths such as 256, 512, 1K, and 4K words. These devices are designed for high-speed data transfer and buffering. The CY7C429 specifically offers 2K x 9 organization. The family supports expansion in width and depth through dedicated control pins.
