Holtek Semiconductor HT45F3830
The HT45F3830 is a device dedicated for use in ultrasonic nebuliser applications. The application principle for ultrasonic nebulisers is to use electronic high-frequency oscillation and ceramic nebulising chip high-frequency resonance to break up the liquid water molecules thus generating a fine mist without requiring heating or any chemical substances. The device is a Flash Memory type 8-bit high performance RISC architecture microcontroller containing special internal circuitry for ultrasonic nebuliser applications.| Part No. | HT45F3830 |
