CY7C425-15JXC

FIFOs Memory Overview

The CY7C425-15JXC is a 1K x 9 asynchronous FIFO memory manufactured by Cypress Semiconductor. It features a maximum access time of 15 ns and operates on a single 5V supply within the commercial temperature range of 0°C to +70°C. The device utilizes a 32-pin Plastic Leaded Chip Carrier (PLCC) package with J-leads. It supports independent read and write operations at speeds up to 50 MHz, includes Full, Empty, and Half Full status flags, and offers retransmit functionality for data packet handling.

FIFOs Memory Feature Summary

• Asynchronous first-in first-out buffer memory architecture
• Dual-port RAM cell design enabling independent read/write cycles
• Retransmit capability for data packet acknowledgment and re-sending
• Expandable in width using dedicated expansion pins

FIFOs Memory Applications

• Buffering data between asynchronous clock domains
• Data flow control in high-speed digital systems
• Packet transfer applications requiring retransmit support
• Width expansion configurations for wider data buses

FIFOs Memory Procurement Notes

Verify the specific ordering suffix 'JXC' confirms the Pb-Free Plastic Leaded Chip Carrier package variant. Confirm the manufacturer source as Cypress Semiconductor or authorized successor Infineon Technologies. Ensure the component meets the required commercial operating temperature range and voltage specifications for your application environment.

FIFOs Memory Selection Notes

Select this part for applications requiring 1K x 9 word depth with a 15 ns access speed. It is suitable for designs needing TTL-compatible inputs and standalone or width-expansion modes. Consider the PLCC package constraints for PCB layout. Verify compatibility with existing system voltage levels and timing requirements against the specified electrical characteristics.

FIFOs Memory Part Context

This component belongs to the CY7C4xx series of asynchronous FIFOs, which includes variants with different depths such as 256x9, 512x9, 2Kx9, and 4Kx9. The series shares common architectural features including dual-port RAM cells and flag logic. The CY7C425 specifically provides the 1K depth option within this family.

FIFOs Memory Replacement Considerations

The datasheet states the device is pin compatible and functionally equivalent to IDT7202, AM7202, and similar parts in the IDT/AMD families. Verify pinout and electrical parameters match before substitution.
