HD614P080S--------------
The HD614P080S
is
a 4-bit single chip microcomputer
which
has
mounted a standard
EPROM
2764/27128 for pro-
gram memory.
The
HD614P080S
is
pin-compatible with the mask
ROM
type HMCS404C/404AC,
but
has some differences with them
as
shown in Table 33.
By
modifying the program in the EPROM,
it can
be
used for the evaluation
of
the HMCS404C/404AC, or
for
small-scale
production.
