CY7C4225-15ASXC

FIFOs Memory Overview

The CY7C4225-15ASXC is a 1K x 18 synchronous FIFO memory manufactured by Cypress Semiconductor. It features an 18-bit data bus width and supports maximum clock frequencies of 66.7 MHz with a minimum cycle time of 15 ns. The device operates within a commercial temperature range of 0°C to +70°C using a single 5V supply. It includes programmable Almost Full/Empty flags, retransmit functionality, and independent read/write enable pins for flexible buffering applications.

FIFOs Memory Feature Summary

• Supports simultaneous asynchronous read and write operations with independent clocks
• Includes programmable Almost Full and Almost Empty status flags
• Features retransmit capability for packet data transfer acknowledgment
• Enables depth expansion through cascade input and output pins

FIFOs Memory Applications

• High-speed data acquisition systems
• Multiprocessor interface buffering
• Communications data buffering

FIFOs Memory Procurement Notes

Verify the specific suffix ASXC against official datasheets to confirm package type and temperature grade. Confirm RoHS compliance status as manufacturing sources may vary. Check current product lifecycle status as Infineon/Cypress products often transition between active and obsolete states.

FIFOs Memory Selection Notes

Select this component when an 18-bit wide synchronous FIFO with 1K depth is required. Ensure system timing meets the 15 ns minimum cycle time requirement. Verify that the 64-pin TQFP or PLCC package fits the PCB layout constraints compared to other density variants in the CY7C42X5 family.

FIFOs Memory Part Context

This part belongs to the CY7C42X5 series of low-power synchronous FIFOs. It shares functional compatibility with IDT722X5 devices. The series offers various densities ranging from 64x18 to 4Kx18, all utilizing advanced 0.65m CMOS technology for high speed and low power consumption.

FIFOs Memory Replacement Considerations

Pin-compatible alternatives include CY7C4225-10AXI (faster speed) or CY7C4225-25ASC (slower speed). Cross-reference with IDT7225L10P for equivalent functionality.
