Abstract

The present invention relates to a semiconductor IC and the microcomputer, a microcomputer with a built-in flash memory, for writing and erasing in a built-in flash memory in a wider external power supply voltage range including low-voltage actions. That is to say, to produce voltage of minimum dependence on power supply voltage (VfixB) by means of basic circuit voltage using the clamping means (44) and within the acceptable range, the voltage level being clamped as a voltage lower than the external single power supply voltage (VCC), thus, by using the surge voltage (writing in and erasing voltage) voltage surge means (45-48) working on clamping voltage (VfixB) without depending on the external power supply voltage (VCC).
