2. DIFFERENCES AMONG

µPD62, 63, 63A, 64, AND µPD6P4B

Table 2-1 shows the differences among the

µPD62, 63, 63A, 64, and µPD6P4B.

The only differences among these models are the program memory, supply voltage, system clock frequency,

oscillation stabilization wait time, and POC circuit (mask option), and the CPU function and internal peripheral

hardware are the same.

The electrical characteristics also differ slightly. For the electrical characteristics, refer to the Data Sheet of each

model.

consumption, differ. For details, refer to Data Sheet of each model.

Note It is necessary to design the application circuit so that the RESET pin goes low when the supply voltage

is less than 2.7 V.
