Abstract

Embodiments of the invention provide an airflow sensor chip and a memory programming method thereof, and an electronic cigarette. The airflow sensor chip comprises a chip body, a multifunctional power supply pin, an airflow sensor and a storage chip, wherein the chip body is used for bearing the multifunctional power supply pin, the airflow sensor and the storage chip; the multifunctional power supply pin is arranged at the edge of the chip body, is electrically connected with the airflow sensor and the storage chip, and is used for providing a power supply for the airflow sensor, loading a programming signal and transmitting the programming signal to the storage chip; and the storage chip is used for storing memory information in the programming signal.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of airflow sensor chips, and more specifically, to an airflow sensor chip, a memory programming method thereof, and an electronic cigarette. Background technique [0002] The airflow sensor is a key component in the application of electronic cigarettes, and the chip plays an important role in the analysis and control of the airflow sensor. Due to space constraints, electronic cigarettes require a small chip area and a small number of external pins. However, with the evolution of technology, the requirements for chip functions and accuracy are getting higher and higher, so built-in memory is required to program key parameters. [0003] At present, the memory programming on the airflow sensor chip of the electronic cigarette requires an additional pin to communicate with the internal memory through the one-wire interface OWI (One Wire Interface) in addition to the pin of the airflow sens...
