<p>PURPOSE:To provide a microcomputer controller whereby the arithmetic ability of a microcomputer is improved by providing a means for setting the access cycle number of the microcomputer as to a memory circuit inside a cycle number setting circuit at an optimum value. CONSTITUTION:The program ROM 10 and the static RAM 12 of this microcomputer controller store processing instruction data of the microcomputer 14 and data which is arithmetically processed by the microcomputer 14. A temp. sensor 36 measures the internal temp. of the controller and an A/D converter 92 converts the power source voltage of the controller. A latch circuit 44 sets the access cycle number which is operated by the microcomputer 14 based on inter-controller temp. and the power source voltage.</p> |
