[HOLTEK New BA45F4140 Dust Detector MCU💨📡]
Holtek is delighted to announce the release of its new dust detector Flash MCU, the BA45F4140. This new device includes a fully integrated dust detector AFE and IR constant current driving circuit, making it excellent use in dust detection products and air quality monitoring applications.
The device contains a 4K×16 Flash Program Memory, a 512×8 Data Memory, a 512×8 EEPROM. With regards to peripheral features, the device also includes multi-functional Timer Modules, a multi-channel 12-bit A/D converter as well as serial communication interfaces. The integrated Multiplier/Divider Unit can be used for dust concentration calculation. The device also includes a temperature sensor which can be used for sensitivity compensation. The high driving current outputs can be used for heater resistor control, and the LDO provides 2.2V/2.5V/3.3V/3.6V outputs to improve system stability. The transmitting, receiving, filtering and amplification circuits, which are required by the dust detector, are all integrated in the device to greatly reduce the need for peripheral components and simplify circuit design.
