The 8051 is an 8-bit microcontroller. Other than these two registers, the 8051 works exclusively with 8-bit values. Multiplication with two operands greater than the number 16 will produce a 16-bit result. Programming Tip: Compared to addition, subtraction, and multiplication, division is a relatively complicated process. Problem – Write a program to subtract two 8-bit numbers with or without borrow where first number is at 2500 memory address and second number is at 2501.

None. A microprocessor is just the processing core - ALU, registers, microcode sequencers, buses, etc. A microCONTROLLER will have peripherals built into the same package and connected to a microprocessor. You will need to check with the specific vendor to see what peripherals are available with which core. Currently, the 8051 is probably the longest lasting, most used 8 bit processor. I suggest looking at data sheets from the following companies: Atmel, Philips, Infineon, and… Read More

Why common cathode connection is used in seven segment display using microcontroller 8051?

The output of 8051 micro controller is active high so we must need to use the common cathode type display . it will work glow when any input is high .
