Air Conditioning System

Application example:

V850 Series Device Features

• LCD controller/driver on chip from 5 x 4 up to 48 x 48 Segments - For displaying temperature or control information.
• 10 Bit A/D converter - For air temperature and humidity measurements.
• Key return ports - For keyboard interface
• UART, SBI or I2C interfaces - For remote communications e.g. for controlling remote motors and additional sensors
• 32 kHz real time clock timer unit - For time and 7 day programming.
• High current output, (20mA) for transistor switch
• Interrupt and timer processing unit for IR decoding function
