Abstract
To provide an electronic circuit device that can change a characteristic after package sealing and that achieves a reduction in miscellaneous tasks during characteristic setting. The electronic circuit device includes: a burst detecting circuitfor detecting, from an input and output terminal, a prescribed write activation burst having a length that is larger than or equal to a prescribed time; a signal-pattern detecting circuitfor putting a serial interfaceinto an input-enable state in which setting data can be input, when the write activation burst is detected; and a volatile memoryand a nonvolatile memoryfor storing, in the input-enable state, a setting-data signal input from the input and output terminal. An operation state of a functional circuitis set in accordance with the setting data written in the volatile memoryor the nonvolatile memory
