CY7C4245-15JXC

FIFOs Memory Overview

The CY7C4245-15JXC is a synchronous FIFO memory with a 4K x 18 bit organization, housed in a 68-pin PLCC package. It supports a maximum clock frequency of 66.7 MHz with a minimum cycle time of 15 ns and a data access time of up to 10 ns. The device operates on a single 5V supply within the commercial temperature range of 0°C to +70°C.

FIFOs Memory Feature Summary

• Supports fully asynchronous and simultaneous read/write operations with independent clocks
• Includes programmable Almost Full and Almost Empty status flags for buffer management
• Enables depth expansion through cascading capabilities using dedicated expansion pins
• Features a retransmit function to facilitate packet data acknowledgment and re-sending

FIFOs Memory Applications

• High-speed data acquisition systems requiring buffering
• Multiprocessor interface data synchronization
• Communications network buffering applications

FIFOs Memory Procurement Notes

Verify that the component matches the specific 68-pin PLCC package configuration. Confirm the -15 speed grade corresponds to the required 66.7 MHz operational frequency. Ensure the voltage supply aligns with the specified 5V requirement for proper functionality.

FIFOs Memory Selection Notes

Select this model when an 18-bit wide data path is necessary alongside a 4K word depth capacity. Consider the PLCC package form factor if existing board layouts require this specific footprint. Evaluate the need for programmable flag offsets and retransmit features before choosing alternative densities.
