Hi,

I think my previous attempt to post this info to the list
didn't make it.

This is a short repost.

I have contacted my local representative of Arizona Microchip
and got the information, that the current revision of the
16C84 has a security problem. AM is in the process of a complete
redesign which will eventually lead to the 16C84A. They expect
this to take long.

The other products (I asked specifically for 16C71 and 16C61)
do not suffer from this problem, according to AM.

I'm now looking for a replacement, which must meet some constraints
AND of course be secure.

1. at most 24 pin SO package, better 18-20.
2. at least 1K OTP-ROM, much better Flash or EE
3. at least 32 bytes RAM, if no internal EE: at least 64 bytes
4. at least 2.7V@5mA, better 2.0V@3mA (of course :))
5. internal (secure) EE preferred, at least 32 Bytes
6. reasonably fast (not dog-slow as ST62xx)

I'm (again) gathering Info starting with Atmel and ending at Zilog.
However, I'd be really glad for any additional specific input from
the list. Any comments?

Mike
