APPENDIX A
DIFFERENCES BETWEEN
μ
PD17246 AND
μ
PD17P246
The
μ
PD17P246 is equipped with PROM to which data can be written by the user instead of the internal mask ROM
(program memory) of the
μ
PD17246.
Table A-1 shows the differences between the
μ
PD17246 and
μ
PD17P246.
The CPU functions and internal hardware of the
μ
PD17P246, 17240, 17241, 17242, 17243, 17244, 17245, and
17246 are identical. Therefore, the
μ
PD17P246 can be used to evaluate the program developed for the
μ
PD17240,
17241, 17242, 17243, 17244, 17245, and 17246 system. Note, however, that some of the electrical specifications
such as supply current and low-voltage detection voltage of the
μ
PD17P246 differ from those of the
μ
PD17240, 17241,
17242, 17243, 17244, 17245, and 17246.
