CY7C429-10JC

FIFOs Memory Overview

The CY7C429-10JC is a 2K x 9 asynchronous FIFO memory manufactured by Cypress Semiconductor. It features a maximum access time of 10 ns and operates at frequencies up to 50 MHz. The device utilizes dual-ported RAM cells for independent read/write operations and supports TTL-compatible inputs. It is housed in a 32-Lead Plastic Leaded Chip Carrier (PLCC) package designed for commercial temperature ranges.

FIFOs Memory Feature Summary

• Asynchronous first-in first-out buffer memory architecture
• Dual-ported RAM cell technology enabling independent read and write cycles
• Hardware flags for Full, Empty, and Half Full status monitoring
• Retransmit capability for data packet acknowledgment and re-sending

FIFOs Memory Applications

• Data buffering between asynchronous clock domains
• Packet storage and retransmission in communication systems
• Depth expansion configurations for increased memory capacity
• Width expansion applications requiring word widths greater than nine bits

FIFOs Memory Procurement Notes

Verify the specific ordering suffix 'JC' corresponds to the 32-Lead Plastic Leaded Chip Carrier package type and Commercial operating range as defined in the official Cypress datasheet. Confirm that the component meets the required voltage and temperature specifications for the intended application environment before procurement.

FIFOs Memory Selection Notes

Select this component when a 2K depth and 9-bit width are required with a 10 ns access speed. Ensure the design accommodates the 32-pin PLCC footprint. Consider the standalone or width expansion modes if flag monitoring across multiple devices is necessary, noting that depth expansion restricts certain flag functionalities.

FIFOs Memory Part Context

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

FIFOs Memory Replacement Considerations

Functionally equivalent substitutes include IDT7203 and AM7203. Verify pin compatibility and electrical characteristics against the original design requirements when considering these alternatives.
