What is psw in 8051?
It is program status register.It i 8 bit ,bit addressable register.It consists of four maths flag.
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
What is the external data memory capacity of 8051 and why?
65536 bytes, because the 8051 family has a 16 bit external address buss.
How do you add and subtract 16 bit numbers using 8051 microprocessor?
The 8051 is a microcontroller, not a microprocessor. To add or subtract, use the ADD or SUBB opcodes.
Who is first invented 8051 microcontroller or 8051 microprocessor?
Intel
Why 8051 is called 8 bit micro controller?
A: Because it can only control 8 bits of data.
8051 pin diagram pin description?
The Intel 8051 is an 8-bit microcontroller which means that most available operations are limited to 8 bits. There are 3 basic "sizes" of the 8051: Short, Standard, and Extended. The Short and Standard chips are often available in DIP form, but the Extended 8051 models often have a different form factor, and are not "drop-in compatable". All these things are called 8051 because they can all be programmed using 8051 assembly language, and they all share certain features (although the different models all have their own special features). Some of the features that have made the 8051 popular are: * 8-bit data bus * 16-bit address bus * 32 general purpose registers each of 8 bits * 16 bit timers (usually 2, but may have more, or less). * 3 internal and 2 external interrupts. * Bit as well as byte addressable RAM area of 16 bytes. * Four 8-bit ports, (short models have two 8-bit ports). * 16-bit program counter and data pointer 8051 models may also have a number of special, model-specific features, such as UARTs, ADC, OpAmps, etc...
Size of stack memory and stack pointer register in 8051 microprocessor?
8 bit
Why 8051 microcontroller called so?
Because it is 8- 8-bit controller (8000 series) 5- It has 5 interrupts 1- It has only one serial communication port
What is psw in 8051?
It is program status register.It i 8 bit ,bit addressable register.It consists of four maths flag.
Write a program to add two 8 bit numbers in microprocessor 8051?
write it in 8085

What is 89c51 microcontroller?
89c51 is an microcontroller of 8051 series it is an 8-bit device packed in 40-pin package.
How do you justify that 8051 is an 8-bit microcontroller?
The 8085 is called an 8 bit microprocessor because the accumulator is 8 bits in size. This means that the primary data size is 8 bits. This is true even though the address bus, certain registers, and certain register operations are 16 bits in size.
How many flags are there in 8051?
8
What is the 16 bit register in the 8051?
pc and stack pointer
