CY7C4275-10ASC

Overview

The CY7C4275-10ASC is a high-speed, low-power synchronous FIFO memory with a 32K x 18-bit organization. It operates at frequencies up to 100 MHz with an 8 ns maximum access time. The device features independent read and write clocks, programmable Almost Full/Empty flags, and retransmit capability. It supports depth and width expansion for larger buffering needs. The component is housed in a 64-pin 10x10 TQFP package and operates within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Supports fully asynchronous and simultaneous read/write operations using independent clock domains.
• Includes programmable status flags for precise buffer level monitoring.
• Enables cascading for increased memory depth or expanded data bus width.
• Provides a retransmit function for reliable packet data transfer.

Applications

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

Procurement Notes

Verify the specific suffix 'ASC' corresponds to the commercial grade operating range and TQFP package configuration. Confirm that the source documentation aligns with the required speed grade of 10 ns. Ensure compatibility with existing system voltage levels and pin assignments before integration.

Selection Notes

Select this model when a 32K x 18 word capacity is required for synchronous buffering applications. Consider the industrial variant if operation below 0°C is necessary. Evaluate the need for depth expansion capabilities if larger storage buffers are required for the specific design constraints.

Part Context

This component belongs to the Cypress CY7C4275/85 family of deep synchronous FIFOs. It shares functional compatibility with the IDT72205/15/25/35/45 series. The device utilizes advanced 0.5 micron CMOS technology to achieve high-speed performance while maintaining low power consumption standards for general-purpose logic applications.

Replacement Considerations

Pin-compatible density upgrades include the CY7C4285 series. Cross-brand compatible replacements from IDT include the 72205, 72215, 72225, 72235, and 72245 models. Verify electrical specifications and timing parameters match the original design requirements when substituting.
