Embedded microcontrollers provide a wide range of applications and help users achieve numerous technical objectives.AT90PWM81-16MN microcontroller is one of the most popular among developers these days. It provides a unique mix of enhanced performance, low voltage operation and an on-board serial communication interface, allowing communication with other devices such as sensors, LCD and other peripherals.In this article, we’ll explore the application field and working principle of AT90PWM81-16MN.

AT90PWM81-16MN is a 8-bit microcontroller based on the Harvard architecture with a 16-bit PWM output.It is specifically designed for applications including motor speed control and light dimming.It features 8K Bytes of in-system programmable Flash, certain data EEPROM, 128 bytes of internal RAM, and three 16-bit Timers/Counters. The device also provides an integrated timer with auto-reload capability, up to four PWM Channels, an I2C-bus interface and built-in voltage regulator.

The most commonly used application of AT90PWM81-16MN is motor speed control. The device is highly suitable for controlling DC motors as it features high PWM resolution and frequency. The motor can be controlled through the I2C-bus or the serial interface. By controlling the PWM duty cycle, the user can set what level of torque and speed the motor should operate at.

Another useful application of AT90PWM81-16MN is light dimming. Users can adjust the brightness of an LED or any other type of lighting unit by changing the PWM duty cycle. In this manner, they can achieve the desired illumination level. Apart from this, the device can also be used for several other applications such as controlling fans and pumps, or switching high current loads.

When it comes to the working principle of AT90PWM81-16MN, the microcontroller is designed around the idea of Pulse-Width Modulation (PWM). PWM is the process of controlling the duty cycle of a signal to control the output. In this case, the duty cycle of the signal is adjusted by changing the CPU timer’s register value that is associated with the PWM channel.The microcontroller is capable of generating up to four PWM channels with up to 16-bit resolution.The duty cycle and frequency of each channel is adjustable and can be adjusted by the user to achieve the desired output.

In conclusion, AT90PWM81-16MN is a high-performing microcontroller that is extremely useful for various applications. Its on-board serial communication interface and an integrated timer allow communication with other devices while its ability to generate up to four PWM channels with up to 16-bit resolution makes it perfect for motor speed control and light dimming. The working principle of this microcontroller is also quite simple, it operates on the idea of Pulse-Width Modulation which is used to adjust the duty cycle of a signal in order to control the output.
