5. DIFFERENCES BETWEEN
m
PD75P3036 AND
m
PD753036
The
m
PD75P3036 replaces the internal mask ROM in the program memory of the
m
PD753036 with a one-time PROM or
EPROM. The
m
PD75P3036’s Mk I mode supports the Mk I mode in the
m
PD753036 and the
m
PD75P3036’s Mk II mode
supports the Mk II mode in the
m
PD753036.
Table 5-1 lists differences among the
m
PD75P3036 and the
m
PD753036. Be sure to check the differences among these
products before using them with PROMs for debugging or prototype testing of application systems or, later, when using
them with a mask ROM for full-scale production.
As to CPU function and on-chip hardware, see the
User’s Manual
.

Noise resistance and noise radiation may differ due to the different circuit sizes and mask
layouts.

is 5.46 ms during 6.0-MHz operation, and 7.81 ms during 4.19-MHz operation.
Caution
Noise resistance and noise radiation are different in PROM and mask ROM versions. In transferring to
mask ROM versions from the PROM version in a process between prototype development and full
production, be sure to fully evaluate the mask ROM version’s CS (not ES).
