CY7C429-15JXC

FIFOs Memory Overview

The CY7C429-15JXC is a 2K x 9 asynchronous FIFO memory component manufactured by Cypress Semiconductor. It features a maximum access time of 15 ns and operates at a frequency up to 50 MHz. The device utilizes dual-port RAM cells for independent read/write operations and supports TTL-compatible inputs. It includes Empty, Full, and Half Full flags to manage data flow. The part is housed in a 32-lead Pb-Free Plastic Leaded Chip Carrier (PLCC) package.

FIFOs Memory Feature Summary

• Asynchronous first-in first-out buffer memory architecture
• Dual-port RAM cell design enabling independent read and write speeds
• Retransmit capability for packet data transfer management
• Expandable depth and width configurations via expansion pins

FIFOs Memory Applications

• High-speed data buffering between asynchronous systems
• Packet data retransmission handling
• Parallel cascadeable memory expansion
• Interface bridging with TTL compatible logic

FIFOs Memory Procurement Notes

Verify the specific ordering suffix JXC confirms the 32-lead Pb-Free Plastic Leaded Chip Carrier package type. Confirm the commercial operating temperature range aligns with system requirements. Ensure the 15 ns speed grade matches the target clock frequency constraints. Cross-reference the manufacturer documentation for any lead-free compliance certifications.

FIFOs Memory Selection Notes

Select this component when a 2K word depth with 9-bit width is required. The 15 ns access time suits applications needing approximately 66 MHz throughput. Verify that the PLCC package fits the PCB layout constraints. Consider the retransmit feature if data integrity checks are necessary before final transmission.

FIFOs Memory Part Context

This part belongs to the CY7C4xx series of asynchronous FIFOs, which includes capacities from 256x9 to 4Kx9. The CY7C429 specifically provides 2048 words of storage. It is functionally equivalent to legacy parts like the IDT7203 and AM7203, facilitating direct pin-compatible replacements in existing designs.

FIFOs Memory Replacement Considerations

Functionally equivalent substitutes include IDT7203L15J and AM7203FC15. Verify pin compatibility and electrical characteristics against the original datasheet specifications before implementation.
