2. DIFFERENCES BETWEEN

µPD67, 67A, 68, 68A, 69, 69A, AND µPD6P9

Table 2-1 shows the differences between the

µPD67, 67A, 68, 68A, 69, 69A, and µPD6P9.

The only differences between these models are the program memory, data memory, timer, POC detection

voltage, and supply voltage; the other CPU functions and internal peripheral hardware are the same.

The electrical specifications also differ slightly. For the electrical specifications, refer to the data sheet of each

model.
