CY7C4245V-15ASXC

FIFOs Memory Overview

The CY7C4245V-15ASXC is a low-voltage synchronous FIFO memory with a 4K x 18 organization, providing 72 kbit of storage capacity. It operates at a maximum clock frequency of 66.7 MHz with an access time of 11 ns. The device supports independent read and write clocks for asynchronous operation and features 3.3V supply voltage compatibility with 5V tolerant inputs. It utilizes a 64-pin TQFP or STQFP package.

FIFOs Memory Feature Summary

• Supports fully asynchronous and simultaneous read and write operations using independent clock domains.
• Includes programmable Almost Full and Almost Empty flags to manage buffer levels dynamically.
• Enables depth expansion through cascade input and output pins for increased buffering capacity.
• Provides a retransmit function to reset the read pointer for packet data acknowledgment.

FIFOs Memory Applications

• High-speed data acquisition systems requiring temporary storage.
• Multiprocessor interfaces needing reliable data handshaking.
• Communications buffering for network protocols.

FIFOs Memory Procurement Notes

Verify component authenticity as this part number belongs to a discontinued product line. Confirm that the specific ordering suffix matches the required package type and temperature range. Check for end-of-life notifications from Infineon Technologies to ensure long-term availability constraints are understood before finalizing design-in decisions.

FIFOs Memory Selection Notes

Select this component when an 18-bit wide synchronous FIFO with 4096-word depth is required. Ensure the system supports 3.3V logic levels while accommodating 5V tolerant input signals. Verify that the application can utilize independent read and write clocks or requires the specific flag programming capabilities offered by this architecture.

FIFOs Memory Part Context

This device is part of the CY7C42X5V family of low-voltage synchronous FIFOs manufactured by Infineon Technologies (formerly Cypress Semiconductor). The family includes variants with different depths ranging from 64 words to 4K words, all sharing the same 18-bit data width and interface characteristics.

FIFOs Memory Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the product is marked as discontinued, alternative sourcing must rely on existing stock or generic compatible devices with matching electrical specifications.
