5. DIFFERENCES BETWEEN
PD75P3018A AND PD753012A, 753016A, AND 753017A
The
PD75P3018A replaces the internal mask ROM in the PD753012A, 753016A, and 753017A with a one-time PROM
and features expanded ROM capacity. The
PD75P3018A’s Mk I mode supports the Mk I mode in the PD753012A,
753016A, and 753017A and the
PD75P3018A’s Mk II mode supports the Mk II mode in the PD753012A, 753016A, and
753017A.
Table 5-1 lists differences among the
PD75P3018A and the PD753012A, 753016A, and 753017A. 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 the CPU functions and internal hardwares, refer to
PD753017 User's Manual (U11282E).

Other
Noise resistance and noise radiation may differ due to the different circuit sizes and mask
layouts.
Note
For 217/fX, during 6.0 MHz operation is 21.8 ms, and during 4.19 MHz operation is 31.3 ms.
For 215/fX, during 6.0 MHz operation is 5.46 ms, and during 4.19 MHz operation is 7.81 ms.
Caution
Noise resistance and noise radiation are different in PROM and mask ROMs. In transferring to mask
ROM version 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).
