How do you burn the software on a 8051 microcontroller?
You will need a 8051 device programmer that connect to a PC with software to drive the programmer
What are the Advantages of at89c52 microcontroller over 8051 microcontroller?
The at89c52 are ones that are more advanced. This means that they are programmable compared to the 8051 which is not. So this makes a really big difference.
What is the advantage of bit addressability for 8051 ports?
a powerful feature of 8051 I/O ports is their capability to access individual bits of the port without altering the rest of the bits in that port. of the four 8051 ports we can access either the entire 8 bits or any single bit without altering the rest
Why there is no driver circuit needed between 8051 microcontroller and an optoisolater?
Are you referring to the original Intel 8051, or one of the many variants? The 8051 has weak internal pullups on the i/o pins, and can source only about 60 ua, but can sink 1.6 ma, still not much when it comes to driving the led in an opto. Some 8051-based dervatives can sink much more current. Atmel's 89C2051 for instance, can sink up to 20 ma per i/o pin. This can directly drive most optos.
What are the advantages of PIC micro-controller over 8051?
In general, personal preference and experience is what it comes down to. There are some PIC's that have built in RF systems; I don't believe there are any 8051's with this capability.
Is 8051 is von nuemann or Harvard architecture?
Atmel's family say that 8051 controller follows the von-nuemann architecture. because register to register operation not possible in all 8051 family. if it is harvard means, it must support register to register transfer.Hence it concludes that 8051 followed by von-nuemann or Princeton architecture...
What is the 16 bit register in the 8051?
pc and stack pointer
Size of stack memory and stack pointer register in 8051 microprocessor?
8 bit
Why the name 8051 as 8051?
because i said so thats why
Who is first invented 8051 microcontroller or 8051 microprocessor?
Intel
How many instruction in 8051 microcontroller?
how many interrupts in 8051
What is the difference between microcontroller 8051 and avr atmega16?
avr is high speed cmpar to 8051.in 8051 there are less number of instructions
What is the function of the register MAR?
it store address.
How much voltage is required to energize the 8051 microcontroller?
The 8051 runs on +5vdc.
Function of flag register?
The main function of flag register is show the status of result stored in accumulator after execution of an instruction. Amar oli Dang,Nepal
What is fullform SBUF?
if you are talking about micro controller, it is "serial buffer". it is used to store the the data if RAM is full! just like queue.
Explain about pin diagram of 8051 micro controller?
The microcontrollers have an 8-bit data bus. They are capable of addressing 64K of program memory and a separate 64K of data memory. The 8051 has 4K of code memory implemented as on-chip Read Only Memory (ROM). The 8051 has 128 bytes of internal Random Access Memory (RAM). The 8051 has two timer/counters, a serial port, 4 general purpose parallel input/output ports, and interrupt control logic with five sources of interrupts. Besides internal RAM, the 8051 has various Special Function Registers (SFR), which are the control and data registers for on-chip facilities. The SFRs also include the accumulator, the B register, and the Program Status Word (PSW), which contains the CPU flags. << SHARMILA TANDEL (B.E) ELECTRONICS >>
