Because its a microcontroller with an 8 bit data bus width.
It is program status register.It i 8 bit ,bit addressable register.It consists of four maths flag.
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
65536 bytes, because the 8051 family has a 16 bit external address buss.
The 8051 is a microcontroller, not a microprocessor. To add or subtract, use the ADD or SUBB opcodes.
Yes, the 8051 microcontroller can perform 16-bit division, but it does not have a dedicated 16-bit DIV instruction. Instead, you can implement 16-bit division by breaking it down into two 8-bit division operations. This involves dividing the high byte and low byte of the dividend separately while managing any remainders appropriately. The process requires additional code to handle the logic for the division.
A: Because it can only control 8 bits of data.
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...
8 bit
Because it is 8- 8-bit controller (8000 series) 5- It has 5 interrupts 1- It has only one serial communication port
It is program status register.It i 8 bit ,bit addressable register.It consists of four maths flag.

89c51 is an microcontroller of 8051 series it is an 8-bit device packed in 40-pin package.
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.
