Question

what is the difference btn microprocessor 8085 and 8051

Answer 1

Answer:

CONTROL UNIT: It provides the necessary timing and control signals to all the operations in the microprocessors. It controls the flow of data between the microprocessor and memory and peripherals. 8035. ... The 8051 is an 8-bit processor, meaning that the CPU can work on only 8 bits of data at a time

Answer 2

8051 Microcontroller

8051 is the microcontroller developed by Intel. Following are the features of 8051 Microcontroller:  

• It houses 8 bit CPU.  

• 4 KByte ROM used for code or program storage  

• 128 Byte RAM to store data or variables used in program  

• 32 Input/Output lines with 4 ports ( 8 lines per port)  

• 2 Timers used for introducing delay and for setting the baud rate for data communication.

8085 Microprocessor

8085 is the microprocessor developed by Intel. Following are the features of 8085 Microprocessor:  

• It is 8 bit size processor developed as single chip using N-MOS.  

• It has multiplexed address and data bus on 8 lines AD0 to AD7.  

• The maximum clock frequency used in 8085 is 3 MHz.  

• It has 40 pins and runs at 5V power supply.  

• There are 5 hardware interrupts viz. TRAP, INTR, RST5.5, RST6.5, RST7.5
