CY7C419-20JC

FIFOs Memory Overview

The CY7C419-20JC is an asynchronous FIFO memory device manufactured by Cypress Semiconductor Corp. It features a memory organization of 256 words by 9 bits, providing a total storage capacity of 2.25 Kbits. The component supports a maximum access time of 20 ns and operates with a cycle time of 30 ns. It utilizes CMOS technology and is housed in a 28-pin Plastic Small Outline J-Lead (SOJ) package. The device includes three-state outputs and functions as a unidirectional buffer.

FIFOs Memory Feature Summary

• Asynchronous operation for flexible interface integration
• Retransmit capability to handle data flow control
• CMOS construction for low power consumption
• Three-state outputs for bus isolation

FIFOs Memory Applications

• Data buffering between microprocessors and peripherals
• Clock domain crossing synchronization
• Interface bridging between different speed logic families

FIFOs Memory Procurement Notes

Verify the specific suffix 'JC' against official Cypress or Infineon documentation to confirm pinout compatibility and voltage levels. Confirm RoHS compliance status as historical data may vary. Check current availability as older SOJ packages are often discontinued or available only through secondary markets. Ensure lead frame material matches system requirements.

FIFOs Memory Selection Notes

Select this part when a small, fast asynchronous FIFO is required for 9-bit data paths. Compare access times against system clock speeds to ensure timing margins. Consider package constraints as SOJ is larger than modern SOP alternatives. Verify that the 20ns access time meets the throughput requirements of the application.

FIFOs Memory Part Context

This component belongs to the CY7C419 family of asynchronous FIFOs. It shares functional similarities with other members like the CY7C419-20VCR but differs in package type and potentially voltage specifications. The family is designed for general-purpose buffering applications requiring simple read/write control signals without complex handshaking protocols.

FIFOs Memory Replacement Considerations

Check for direct replacements within the CY7C419 series such as CY7C419-20VCR for package differences. Verify if newer generations from Infineon offer pin-compatible upgrades. Ensure any substitute maintains the 256x9 organization and 20ns minimum performance.
