DIFFERENCES BETWEEN

µPD17P218 AND µPD17215/17216/17217/17218

The

µPD17P218 is a model of the µPD17218 provided with a one-time PROM as the program memory, to which

the user can write data, instead of an internal mask ROM.

Table 1-1 shows the differences among the

µPD17P218, µPD17215, 17216, 17217, and 17218.

These five products have different memory capacities and mask options but the same CPU function and internal

hardware. Therefore, the

µPD17P218 can be used to evaluate the program of a system using the µPD17215, 17216,

17217, or 17218. Note that part of the electrical specifications of the

µPD17P218 such as supply current and low-

voltage detection voltage are different from those of the

µPD17215, 17216, 17217, and 17218.

For the detail of the CPU functions and internal hardware, refer to the Data Sheet of the

µPD17215, 17216, 17217,

and 17218.
