APPENDIX A.
DIFFERENCES BETWEEN
μ
PD17236 AND
μ
PD17P236
μ
PD17P236 is equipped with PROM to which data can be written by the user instead of the internal mask ROM
(program memory) of the
μ
PD17236.
Table A-1 shows the differences between the
μ
PD17236 and
μ
PD17P236.
The CPU functions and internal hardware of the
μ
PD17P236, 17230, 17231, 17232, 17233, 17234, 17235, and
17236 are identical. Therefore, the
μ
PD17P236 can be used to evaluate the program developed for the
μ
PD17231,
17232, 17233, 17234, 17235, and 17236 system.
Note, however, that some of the electrical specifications such
as supply current and low-voltage detection voltage of the
μ
PD17P236 are different from those of the
μ
PD17231, 17232, 17233, 17234, 17235, and 17236.
