Updated naming convention for 8-bit devices ??

Hello Alban,
 
In the referenced post you are advocating that the 'HC' prefix be dropped for the 16-bit devices, as being more trendy.
 
What are your thoughts concerning 8-bit devices?
 
To be totally consistent (and trendy?) should we be referring to 08xxx, S08xxx and RS08xxx parts from now on?  Will this also be reflected in new releases of documentation?  What about the full part numbers used for ordering purposes?
 
Regards,
Mac

Hi Mac,
 
This has already happened.
What was a MC68HC908GP32CFB
is now a MC908GP32CFBE
They dropped the whole 68HC. (The extra E on the end is for RoHS)
 
S08's have always been MC9S08xxyyzzz
 
Given that then it safe to always drop the MC
and probably the 9 as I'm sure most of the stuff talked about here is 9. If its not 9 then you should specify.
So now the same rules would apply as for 12
Care needs to be taken to include letter suffixes that describe internal changes and not packaging options though.

Hello,
 
For HC08 it is difficult to say, a lot of people call them "08's" but as it is an old family, I don't see much benefit to eliminate HC08 as it keeps letter to clearly identify we talk about FSL MCU.
 
But for the newer parts, HC is redundant and confusing also (because people drop the "S" sometimes).
 
I would need to find someone in 8-bit to do the cleaning on FSL side...
 
The MC is usually safe to drop because very little people work with prototypes, noted PC.
MC means fully qualified.
PC means engineering samples.
XC (obsolete) means prototype.
 
Then, the 9 can usually be omitted because of the context.
9 means flash,
3 means ROM,
7 means OTP.
 
Alban.
