APPENDIX A.

DIFFERENCES BETWEEN

µPD17236 AND µPD17P236

µPD17P236 is equipped with PROM to which data can be written by the user instead of the internal mask ROM

(program memory) of the

µPD17236.

Table A-1 shows the differences between the

µPD17236 and µPD17P236.

The CPU functions and internal hardware of the

µPD17P236, 17230, 17231, 17232, 17233, 17234, 17235, and

17236 are identical. Therefore, the

µPD17P236 can be used to evaluate the program developed for the µPD17231,

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

µPD17P236 are different from those of the

µPD17231, 17232, 17233, 17234, 17235, and 17236.
