What is vpp in 8051 pin diagram?
In the 8051 microcontroller pin diagram, Vpp refers to the programming voltage pin, which is used during the programming of the microcontroller's memory. It is typically set at a high voltage (around 12V) to enable the programming mode for the internal flash or EPROM. This pin is crucial for writing data into the memory during the initial programming phase and is not used during normal operation.
Is adc present on chip in 8051 or not?
There is no formal adc input on the 8051. However, the CMOS version of the chip can use a technique involving a resistor, diode, and capacitor, along with a bidirectional pin (or one output pin and one input pin) to implement a "quick and dirty" adc function. You discharge the capacitor and then let it charge to the voltage of the input. You measure the time it takes to see the input pin change, and you calculate the input voltage.
Difference between 8031 8051 and 8751 microcontrollers?
Answer It is both 8 bit processors in a 40 pin package but it is not pin compatible, it have almost the same functions but it is very difficult to compare the two because it is not the same family.
Who is first invented 8051 microcontroller or 8051 microprocessor?
Intel
Advantages of at89c51 microcontroller over 8051 microcontroller?
the 8051 microcontrroller is the name doesnt matter easy or not....but the maiin and imp diff between both is at89s51 represents the 8051 chip no....along with the name of company i.e atmel, so all n all both are same thing ...... 89c51 have RISC architecture and contains less no of opcodes which are easy for programming. so iti is preferred than 8051.
What are the control signals for 8051 micro controller?
EA - External Access PSEN - Program store Enable ALE - Address Latch Enable RST - Reset WR - RD

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.

How many instruction in 8051 microcontroller?
how many interrupts in 8051
Why the name 8051 as 8051?
because i said so thats why
Differences between Intel 8051 and atmel 89c51 micro controller?
The instructions used by Atmel 89CXX and 89CXXXX are the same or subset of 8051 microcontrollers.Fully static operation,flash program memory,less pin count andprecision analog comparator ( in case of 89C20510)are some of the attractions in going for these microcontrollers. Due to many similar features in the architecture and instruction and instruction set as that of 8051, it becomes possible for the 8051 designer to directly start using 89CXX and 89C20XX microcontrollers without any more efforts in learning these microcontrollers.
