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.
