I'm not quite sure what you mean. A microcontroller is simply a CPU with some RAM, ROM, and peripherals, all on one chip. You could design a circuit around an 8085 which would provide the same functionality, but unless you've got some ancient code that you want to run, there's not much point in that. Much easier would be an off-the-shelf, single-IC microcontroller. The 8051, a widely-used Intel part, will have a similar feel to the 8085, while a PIC or AVR would be a more modern choice.
What else can I help you with?
Is microprocessors use in inverters?
Microprocessor is used where we require more m/m and data. microcontroller is best option for inverters,but in a case if we want to improve, or want to make it advance such as with some conditions then we use microprocessor
Draw a schemetic to demultiplex bus ad0-ad7 using any octal latch in 8085 microprocessor?
The 8085 microprocessor is used IC 74LS373 to latch the address of 8085. Basically latch is consists of 8 flip flops. Generally we used D-flip flops (Delay).The clock of these flip flops are connected together and available as a output pin called enable.Working : The address will appear on AD0 AD7 lines. The ALE will go high and forcingEnable = 1. This will make latch enable and ready to work. Before address disappears ALE = 0. This will make latch disable. AD0 - AD7 will now be used as data bus.Hence, AD0 - AD7 (low order) address bus of the 8085 microprocessor is multiplexed (time-shared) with the data bus. The buses need to be demultiplexed.
What are the advantages and disadvantages of using microcontroller over microprocessor?
disadvantage: microcontrollers have got more comlex architecture than that of microprocessors so to understand it's functionality is quite difficult. advantage: microprocessors have got faster speed of execution than that of microprocessor.Also because of microcontroller embedded system got on the peak of it's development to make new electronc devices.
Why is microcontroller needed?
A microprocessor cant work as a stand alone unit.to make it work we have to interface memory and input out devices and so the PCB of microprocessor based system will be larger.Microcontroller consists of processor,memory and peripherals on a single chip and so needs no interfacing.Microcontroller can be programmed for any specific task.
What are different point s between microprocessor and micro-controller?
Microprocessor = CPU Microcontroller = CPU+peripherals+memory A CPU cannot run independently, it needs peripherals and memory circuits. In embedded systems microcontroller designs are easier than microprocessor design. For example 8051 controllers will have EEPROM, RAM, timer circuit, serial port, SPI, GPIO, etc. If ur application need not have all these, just EEPROM, RAM, GPIO is enough then u can go for 8058 CPU with 8055, EEPROM, RAM. In otherwords CPU designs may provide more flexibility to ur Embedded design. whereas microcontroller designs can make designing easier. Hope this may help u !!
What is bus with reference to microprocessor 8085 system?
A Bus is a set of data/control lines which are basically just a group of wires. e.g if 8085 wants to send 0xFF (255) to an Output device, it would make all the lines of the data bus high, bcoz 0xFF is 11111111 in binary, that is to say all the wires of the bus are 1. (1 means at +5V). -munish
Can we make 8051 microcontroller based plc?
yes

How do you interface nunchuk with microcontroller?
To interface a nunchuk with a microcontroller, you typically connect the nunchuk to the microcontroller's I2C bus, using the SDA and SCL lines. The nunchuk requires power (usually 3.3V) and ground connections. You can then use a library or write custom code to read the data from the nunchuk, which includes joystick position and button states, by sending and receiving I2C messages. Make sure to properly initialize the I2C communication and handle data processing in your microcontroller's firmware.
How load shedding and load balancing is control by using a microcontroller?
Load shedding and load balancing can be controlled using a microcontroller by monitoring the electrical load and system parameters in real-time. The microcontroller can be programmed to disconnect non-essential loads during peak demand (load shedding) while redistributing the remaining loads across available circuits (load balancing) to optimize energy use. By implementing algorithms that prioritize critical loads and using sensors for data collection, the microcontroller can make dynamic adjustments to maintain system stability and efficiency. This approach enhances energy management in various applications, from industrial setups to smart homes.
The difference block diagram between microprocessor and microcontroller?
