5. DIFFERENCES BETWEEN
m
PD75P0116 AND
m
PD750104, 750106, AND 750108
The
m
PD75P0116 replaces the internal mask ROM in the
m
PD750104, 750106, and 750108 with a one-time PROM
and features expanded ROM capacity. The
m
PD75P0116’s Mk I mode supports the Mk I mode in the
m
PD750104, 750106,
and 750108 and the
m
PD75P0116’s Mk II mode supports the Mk II mode in the
m
PD750104, 750106, and 750108.
Table 5-2 lists differences among the
m
PD75P0116 and the
m
PD750104, 750106, and 750108. Be sure to check the
differences between corresponding versions beforehand, especially when a PROM version is used for debugging or
prototype testing of application systems and later the corresponding mask ROM version is used for full-scale production.
Please refer to the
m
PD750108 User's Manual (U11330E)
for details on CPU functions and on-chip hardware.

Caution
Noise resistance and noise radiation are different in PROM version and mask ROM versions. If using
a mask ROM version instead of the PROM version for processes between prototype development and
full production, be sure to fully evaluate the CS of the mask ROM version (not ES).
