5. DIFFERENCES BETWEEN PD75P3036 AND PD753036
The PD75P3036 replaces the internal mask ROM in the program memory of the PD753036 with a one-time PROM or
EPROM. The PD75P3036’s Mk I mode supports the Mk I mode in the PD753036 and the PD75P3036’s Mk II mode
supports the Mk II mode in the PD753036.
Table 5-1 lists differences among the PD75P3036 and the 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.
