Hi all - my first post here! :)

I wanted to share some information regarding EAR classification of some WDC 65Cxx parts on mouser.com. I recently tried to order the following parts:

955-W65C816S6PG-14
955-W65C51N6TPG-14
955-W65C22S6TPG-14
955-W65C02S6TPG-14

Some of you might know that Mouser will automatically block your order with certain classifications and attach a form to fill out, stating your intention to export (or not). I found out that these were classified with an Export Control Classification Number (ECCN) of 3A001.a.2 - which includes:

Quote:
Microprocessor microcircuits”, “microcomputer microcircuits”, microcontroller microcircuits, storage integrated circuits manufactured from a compound semiconductor, analog-to-digital converters, digital-to-analog converters, electro-optical or “optical integrated circuits” designed for “signal processing”, field programmable logic devices, custom integrated circuits for which either the function is unknown or the control status of the equipment in which the integrated circuit will be used in unknown, Fast Fourier Transform (FFT) processors, electrical erasable programmable read-only memories (EEPROMs), flash memories or static random-access memories (SRAMs), having any of the following:

a.2.a. Rated for operation at an ambient temperature above 398 K (+125 ̊C);
a.2.b. Rated for operation at an ambient temperature below 218 K (-55 ̊C); or
a.2.c. Rated for operation over the entire ambient temperature range from 218 K (-55 ̊C) to 398 K (125 ̊C);

https://www.bis.doc.gov/index.php/regulations/export-administration-regulations-ear

None of the 65xx parts that I could see went beyond these lower and upper operating temperature bounds, so I e-mailed both WDC and Mouser about why these chips are classified as such. They both responded directly very quickly. I won't speak directly for them, but I think I can relay that this classification was a miscommunication, that WDC is working on getting their chips classified properly as EAR99 (no license required), and then Mouser can remove this restriction.

Also, Mouser has also communicated to me that, if you don't intend to export from the US at all, you don't need to fill out and sign the form for these - just send an e-mail to export@mouser.com with your order number saying as much if you get the notice in your order confirmation. Although, once the classification is cleared up, hopefully you can order in the US with no hurdles, and also similarly get international delivery to non-embargoed/sanctioned countries.

I know you can probably get these from other distributors but Mouser is pretty popular, so I thought I'd post this information here. I hope this helps!

Yes, I had a similar experience with Mouser last year... in my case I had a W65C134 chip in my order, which has copyrighted software in the internal ROM. I've ordered the other chips from Mouser before (sans the 816 CPU) without any issue and no EAR form. In the case of your order, this should not be the case and I suspect it's an error on their part... likely on the 816 chip.

Do note however that the 65C51 chips are known defective and won't work as expected. Mouser recently obtained additional stock as their existing DIP versions were out. I ordered one of them about a month ago (no EAR form required) and it's the same bad chip. For more information on the 65C51 issue, read this thread:

Best of luck on your 6502 based projects... great set of resources out here should you have any issues.
