It is based on 8-bit and 8051 core platform. The low-power, low-voltage device is ideal for use in portable appliance, industrial control, home appliances and other embedded systems, with potential applications including metering and counting, motor speed control, audio frequency control and power supply. It also has some of the features of digital communications, motor control and LCD control.
2 Application field
The DF2145BFA20V has a number of features that make it suitable for many applications. It is a low-power and low-voltage microcontroller that is ideal for use in portable appliances, industrial control, home appliances and other embedded systems. In addition, due to its various integrated peripherals and timers, it can be used for a variety of applications including metering, counting, motor speed control, audio frequency control and power supply, as well as for digital communications, motor control and LCD control.
For example, it is suitable for integration into energy-saving lighting control systems. The integrated timer and pulse width modulation (PWM) output can be used to control the power supply voltage, which can save energy by dimming or turning off the lights automatically when it’s not needed. Also, it can be used in remote monitoring systems, as the built-in communication peripheral devices, such as RS-232, CAN, SPI and I2C, provide a means of connecting to external sensors and other nodes.
In industrial control applications, it can be used for motor speed, torque and position control, as well as for power supply and logic control. Its ADC, DAC and EEPROM support functions can be used for data recording and processing. The integrated LCD interface can be used for data display.
3 Working Principle
The working principle of DF2145BFA20V can be divided into several parts. First, it is based on an 8-bit, 8051-core platform. This means that the MCU can execute 8-bit operations. It also has a bus interface unit that can connect to external memory and peripherals, such as LCD displays and communications interfaces. Second, it has an internal memory map, which divides the address space into different areas. Each area is designated to a specific type of memory, such as program memory, data memory, port pins or peripherals.
The MCU is controlled by the program stored in program memory. The program is made up of instructions that contain the opcodes for operations, as well as the required data. The internal timers and counter are then used to monitor the program execution and to control the peripherals. Finally, the data is stored in the data memory, and then the results of the execution are sent back to the port pins.
4 Conclusion
In conclusion, the DF2145BFA20V is a 40-pin single-chip microcontroller that belongs to the embedded microcontroller. It is based on 8-bit and 8051-core platform, and has a number of features that make it suitable for use in a variety of applications. These features include its low-power, low-voltage design, integrated peripherals and timers, as well as its programmable port pins, ADC, DAC and EEPROM. Finally, the working principle of the MCU is based on its 8-bit, 8051-core platform, memory map and internal timers and counter.
