CY7C419-15JXCT

FIFOs Memory Overview

The CY7C419-15JXCT is an asynchronous first-in first-out (FIFO) buffer memory with a storage capacity of 2.25K bits, organized as 256 words by 9 bits. It features a maximum clock frequency of 50 MHz and a typical access time of 15 ns. The device operates on a single 5V supply voltage ranging from 4.5 V to 5.5 V, with a maximum operating current of 35 mA. It utilizes a parallel interface and is housed in a 32-pin Plastic Leaded Chip Carrier (PLCC) package.

FIFOs Memory Feature Summary

• Asynchronous read and write operations independent of depth and width
• Dual-ported RAM cell architecture for high-speed performance
• Retransmit capability in standalone configurations
• Expandable in width using dedicated expansion pins

FIFOs Memory Applications

• Buffering data between components operating at different speeds
• Data flow control in communication systems
• Interface bridging in digital signal processing applications

FIFOs Memory Procurement Notes

Verify the specific suffix JXCT against official documentation to confirm lead-free status and package dimensions. Confirm that the component is sourced from authorized distributors to ensure authenticity. Check for obsolescence notices or lifecycle changes prior to finalizing procurement plans.

FIFOs Memory Selection Notes

Select this model when a 256x9 word depth is required for asynchronous buffering. Ensure the system design supports a single 5V power supply. Verify that the 32-pin PLCC package footprint matches the PCB layout requirements. Consider expansion capabilities if wider data paths are needed.

FIFOs Memory Part Context

This component belongs to the CY7C419/21/25/29/33 family of asynchronous FIFOs manufactured by Cypress Semiconductor, now part of Infineon Technologies. The family offers various depths ranging from 256 to 4096 words, all maintaining a 9-bit width and similar functional characteristics.

FIFOs Memory Replacement Considerations

The datasheet lists IDT7200, IDT7201, AM7200, and AM7201 as pin-compatible and functionally equivalent alternatives.
