µPD75P3036

5. DIFFERENCES BETWEEN µPD75P3036 AND µPD753036

The µPD75P3036 replaces the internal mask ROM in the program memory of the µPD753036 with a one-time PROM or

EPROM. The µPD75P3036’s Mk I mode supports the Mk I mode in the µPD753036 and the µPD75P3036’s Mk II mode

supports the Mk II mode in the µPD753036.

Table 5-1 lists differences among the µPD75P3036 and the µPD753036. 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.

Note 217/fX is 21.8 ms during 6.0-MHz operation, and 31.3 ms during 4.19-MHz operation.

215/fX 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).
