APPENDIX A
(program memory) of the µ PD17246.
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.
Notes 1. Although the circuit configuration is identical, the electrical characteristics differ depending on the product.
