67C402-10N

Overview

The AMD 67C402-10N is an asynchronous FIFO memory IC organized as 64 x 5 bits. It features a maximum access time of 34 ns and a cycle time of 40 ns, corresponding to a 10 MHz operating frequency. The device utilizes CMOS technology and is housed in a 20-pin PDIP package. It functions as a uni-directional buffer for high-speed data transfer applications.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• CMOS RAM-based architecture for low power consumption
• Uni-directional data flow buffering capability

Applications

• High-speed data transfer buffering between disparate system speeds
• Temporary data storage in digital signal processing chains
• Interface bridging between microprocessors and peripheral devices

Procurement Notes

Verify the specific suffix '10N' to confirm the 10MHz speed grade and PDIP package type. Confirm availability status as this component may be discontinued or superseded by newer revisions. Ensure compatibility with existing voltage levels and logic families before integration into new designs.

Selection Notes

Select this part when a 64-word by 5-bit depth is required for asynchronous buffering. Compare against the 67C401 (64x4) if narrower data paths suffice. Consider the 67C402-25N variant if slower speeds are acceptable but cost is a primary driver. Verify pinout compatibility with existing PCB layouts.

Part Context

This component belongs to the Advanced Micro Devices 67C40X series of high-performance CMOS FIFOs. The series includes variants like the 67C401 and 67C402, differing primarily in data width. These devices are designed for reliable data storage in communication and computing systems requiring temporary holding buffers.

Replacement Considerations

Check for direct replacements within the 67C402 family with different speed grades. Verify if newer CMOS FIFO generations from AMD or other manufacturers offer pin-compatible upgrades with improved performance metrics.
