CY7C464A-15JC

FIFOs Memory Overview

The CY7C464A-15JC is a 32K x 9 asynchronous FIFO memory manufactured by Infineon Technologies. It features a 15 ns maximum access time and supports read/write operations at frequencies up to 40 MHz. The device operates on a single 5V ± 10% supply with a maximum operating current of 60 mA. It utilizes a 32-lead Plastic Leaded Chip Carrier (PLCC) package designed for surface-mount applications.

FIFOs Memory Feature Summary

• Supports independent asynchronous read and write operations
• Provides Full, Empty, and Half Full status flags
• Enables depth expansion through cascading capabilities
• Includes retransmit functionality for data packet handling

FIFOs Memory Applications

• Buffering data between components operating at different clock speeds
• Managing data flow in telecommunications systems
• Implementing serial-to-parallel conversion logic
• Facilitating data transfer in high-speed digital interfaces

FIFOs Memory Procurement Notes

Verify the component manufacturer as Infineon Technologies or its predecessor Cypress Semiconductor. Confirm the specific speed grade suffix matches the required 15 ns access time. Ensure the package type corresponds to the 32-lead PLCC configuration. Check for RoHS compliance status as older revisions may not meet current environmental standards.

FIFOs Memory Selection Notes

Select this component when a 32K word depth with 9-bit width is required. Choose this part if asynchronous operation without a shared clock is necessary. Consider this option for designs requiring hardware-based flow control via flag outputs. Evaluate the 15 ns speed grade against system timing constraints.

FIFOs Memory Part Context

This device belongs to the CY7C46xA family of asynchronous FIFOs. It shares architectural similarities with the CY7C460A, CY7C462A, and CY7C466A models. These parts offer pin-compatible density upgrades within the same series. The family utilizes advanced CMOS technology for low power consumption.

FIFOs Memory Replacement Considerations

The datasheet identifies IDT7205, IDT7206, IDT7207, and IDT7208 as functionally equivalent alternatives.
