This was taking into account the OP who may misread your reply and still 
think that his 2138 should have fast I/O. Tacking a suffix onto a part 
will not draw attention to the fact that it is a different part you are 
talking about unless you emphasize that, especially as it is so new.

Only in retrospect.

Truth be known I was not aware that Philips/NXP had released them yet. I 
notice that my last weekly "Philips Semiconductor News" was received 
last month. I am sure they would have announced this /01 part in the 
weekly bulletin but maybe with all the brand name changes this e-feature 
is still being updated.

Thank-you for bring the /01 to my attention.
