CY7C4265-15AXCT

Overview

The CY7C4265-15AXCT is a synchronous first-in, first-out (FIFO) memory component manufactured by Infineon Technologies. It features an organization of 16 k x 18 bits, providing a total storage capacity of 288 kbit. The device operates with a maximum clock frequency of 66.7 MHz and supports unidirectional data bus transfer. Electrical specifications include a supply voltage range of 4.5 V to 5.5 V and a maximum power supply current of 45 mA. The component is housed in a TQFP-64 surface-mount package and is rated for commercial operating temperatures between 0°C and +70°C.

Feature Summary

• Synchronous FIFO architecture with dedicated read and write control logic
• Unidirectional data transfer capability via 18-bit parallel interface
• Integrated status flags indicating full, empty, and half-full conditions

Applications

• Data buffering in high-speed digital signal processing systems
• Interface bridging between components operating at different clock domains
• Temporary data storage in telecommunications equipment

Procurement Notes

Verify the complete part number suffix against official Infineon documentation to confirm specific package variants and temperature grades. Confirm end-of-life status and availability through authorized distributors, as this component may be subject to limited supply or replacement programs. Ensure compliance with RoHS directives and moisture sensitivity levels prior to procurement.

Selection Notes

Select this component when a synchronous FIFO solution with 18-bit word width is required. Verify that the system clock does not exceed the maximum specified frequency. Ensure the design accommodates the 5V logic level requirements and the physical dimensions of the TQFP-64 package. Consider thermal dissipation capabilities within the specified commercial temperature range during board layout.

Part Context

This part belongs to the CY7C4265 series of synchronous FIFOs from Infineon Technologies. The series provides reliable data buffering solutions for applications requiring controlled data flow rates. The specific model denotes the 15 ns access speed variant packaged in TQFP format, designed for commercial grade environments.

Replacement Considerations

Consult official Infineon obsolescence notices for qualified replacement part numbers. Cross-reference pinouts and electrical characteristics with alternative synchronous FIFO devices if direct substitutes are unavailable.
