5. DIFFERENCES BETWEEN
m
PD75P3216 AND
m
PD753204, 753206, AND 753208
The
m
PD75P3216 replaces the internal mask ROM in the
m
PD753204, 753206, and 753208 with a one-time PROM
and features expanded ROM capacity. The
m
PD75P3216’s Mk I mode supports the Mk I mode in the
m
PD753204, 753206,
and 753208 and the
m
PD75P3216’s Mk II mode supports the Mk II mode in the
m
PD753204, 753206, and 753208.
Table 5-1 lists differences among the
m
PD75P3216 and the
m
PD753204, 753206, and 753208. 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.
For details on the CPU functions and internal hardware, refer to

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

Caution
Noise resistance and noise radiation are different in PROM and mask ROMs. 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).
