APPENDIX A. DIFFERENCES AMONG
μ
PD17225, 17226, 17227, 17228 AND
μ
PD17P218
μ
PD17P218 is equipped with PROM to which data can be written by the user instead of the internal mask ROM
(program memory) of the
μ
PD17228.
Table A-1 shows the differences between the
μ
PD17225, 17226, 17227, 17228 and
μ
PD17P218.
The differences among these five models are the program memory and mask option, and their CPU functions and
internal hardware are identical. Therefore, the
μ
PD17P218 can be used to evaluate the program developed for the
μ
PD17225, 17226, 17227, and 17228 system.
Note, however, that some of the electrical specifications such
as supply current and low-voltage detection voltage of the
μ
PD17P218 are different from those of the
μ
PD17225, 17226, 17227, and 17228.
