Electrically programmable circuit for generating internal supply voltage

摘要

a) Electrically programmable circuit for generating internal supply voltage. b) Circuit for generating internal supply voltage characterised in that it comprises: voltage detection means (100) intended for detecting a voltage applied to a given attenuator (10); reference voltage control means linked to the voltage detection means so as to control a given reference voltage produced by a reference voltage generator (50), so as to produce the reference voltage or the external supply voltage; and means (400) for generating internal supply voltage and which are linked to the reference voltage control means to produce the internal supply voltage as a function of the output signal from the reference voltage control means. <IMAGE>
