67C4033-10NL

Overview

The 67C4033-10NL is an asynchronous First-In-First-Out (FIFO) memory buffer manufactured by Advanced Micro Devices. It features a 64 x 5 word organization, providing 64 words of depth with a 5-bit data width. The device operates at a maximum clock frequency of 10MHz and supports uni-directional data transfer. Packaged in a 20-pin Dual In-line Package (DIP), it utilizes CMOS RAM-based technology to ensure high performance and low latency for data buffering applications.

Feature Summary

• Asynchronous operation enables low-latency data transfer between domains
• Uni-directional data flow architecture simplifies interface design
• CMOS RAM-based construction ensures high performance reliability

Applications

• Data buffering in digital signal processing systems
• Interface bridging between asynchronous logic blocks
• Temporary storage in high-speed data acquisition circuits

Procurement Notes

Verify the specific suffix 'NL' against the manufacturer's official documentation to confirm package type and material compliance. Ensure the 20-DIP footprint matches your PCB layout requirements. Confirm that the 10MHz operating speed meets your system timing constraints before procurement.

Selection Notes

Select this component when a simple, uni-directional asynchronous buffer is required. The 64x5 configuration suits applications needing moderate depth with narrow data paths. Consider the 20-DIP package only if through-hole mounting is necessary for mechanical stability or prototyping purposes.

Part Context

This part belongs to the 67C4033 series of asynchronous FIFOs from Advanced Micro Devices. It shares architectural similarities with other devices in the family but differs in data width and pinout. The series is designed for general-purpose buffering tasks where clock domain crossing is not strictly synchronous.

Replacement Considerations

Check for direct substitutes such as the 67C4033-15NL for slower speed variants. Verify compatibility with similar FIFOs from other manufacturers regarding pinout and voltage levels before substitution.
