67C4033-15N

Overview

The AMD 67C4033-15N is an asynchronous FIFO memory IC organized as 64 words by 5 bits. It operates at a maximum clock frequency of 15MHz with a typical access time of 47ns. The device utilizes CMOS technology and supports full-write-first (FWFT) functionality for reliable data buffering. It is housed in a 20-pin PDIP package designed for through-hole mounting, suitable for uni-directional data transfer applications within the specified commercial temperature range.

Feature Summary

• Asynchronous first-in-first-out memory architecture for independent read/write clock domains
• Uni-directional data buffering capability with full-write-first support
• CMOS technology ensuring high performance and low power consumption

Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging between systems operating at different clock speeds
• Serial-to-parallel or parallel-to-serial data conversion buffers

Procurement Notes

Verify the specific suffix '15N' to confirm the 15MHz speed grade and PDIP-20 package configuration. Ensure compatibility with through-hole assembly processes. Confirm RoHS compliance status if required for your manufacturing environment. Cross-reference datasheet electrical characteristics against system timing requirements before finalizing procurement.

Selection Notes

Select this component when a 64x5 word depth is required for asynchronous data buffering. The 15MHz speed rating suits moderate-speed interface applications. Consider the 20-PDIP package only if through-hole mounting is mandated by the PCB design. Verify that the 5-bit word width aligns with the data bus requirements of the connected logic components.

Part Context

This part belongs to the AMD 67C4033 series of asynchronous FIFO memories. Variants such as the 67C4033-10N offer lower speed ratings, while other packages like PLCC may be available. The series provides standardized buffering solutions for legacy and industrial systems requiring reliable data flow management between asynchronous domains.

Replacement Considerations

The 67C4033-10N serves as a slower alternative within the same family. Verify pinout compatibility and electrical specifications before substitution. No direct cross-manufacturer equivalents are confirmed in public documentation without additional verification.
