Well, I checked my 1980 National Semi MCS-48 data book
and found not
only
that there was no 8154, but that the 8155 and 8156
were not listed
(yet)
either. They did make them, however, because I have
them (INS8155,56)
among
my parts.
The NS8156/55 were introduced a year or so later.
would appear together with products coming from device
families intended
to
replace the MCS-48. It must have lived iwithin a
fairly narrow window.
National did the 804x for a while.
NEC and a few others made the 8155 and '56, so they
might have made a
version of the 8154 as well.
They did not. the 8154 was an oddball part.
