µPD75P3116 AND µPD753104, 753106, 753108

The 

µPD75P3116 replaces the internal mask ROM in the µPD753104, 753106, and 753108 with a one-time PROM

and features expanded ROM capacity.  The 

µPD75P3116’s Mk I mode supports the Mk I mode in the µPD753104, 753106,

and 753108 and the 

µPD75P3116’s Mk II mode supports the Mk II mode in the µPD753104, 753106, and 753108.

Table 5-1 lists differences between the 

µPD75P3116 and the µPD753104, 753106, and 753108.  Be sure to check the

differences between 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 of the CPU functions and internal hardware, refer to the User’s Manual.
