Its data bus width is 8bit and address bus width is 16bit, thus it can address 216 64 kb of memory. The address bus is a group of 16 lines generally identified as a0 to a15. In this article you will get to know about the definition, architecture, block diagram and working of 8085 microprocessor. Uses data from memory and from accumulator to perform arithmetic.
These flipflops are set or reset according to the data condition of the result in the accumulator and other registers. Each read or writes operation constitutes a machine cycle. Intel 8085 8bit microprocessor intel 8085 is an 8bit, nmos microprocessor. In addition to the above mentioned registers intel 8085 microprocessor also contains. It is a 40 pin c package fabricated on a single lsi chip. Lecture note on microprocessor and microcontroller theory. The microprocessor 8086 is a 16bit cpu available in different clock rates and packaged in a 40 pin cerdip or plastic package. The 8085 architecture consists of control unit, alu, registers, accumulator, flags, program counter, stack pointer, instruction register, memory address register, control register etc. This processor is the updated version of the microprocessor. The applications of 8085 microprocessor include microwave ovens. The builtin clock generator of 8085, in block schematic, is shown below. This 8085 architecture describes 8085 microprocessor internal modules with block diagram.
Before introduction of the microprocessor circa 1960s, hardwired controllers were used in motor drive applications 30. The time for the back cycle of the intel 8085 a2 is 200 ns. In 1971, intel corporation came out with a 4bit microprocessor intel. Draw the block diagram of the builtin clock generator of 8085.
Pin diagram of 8085 microprocessor is as given below. The intel 8085 eightyeightyfive is an 8bit microprocessor produced by intel and introduced. The functional block diagram or architechture of 8085 microprocessor is very important as it gives the complete details about a microprocessor. A linker is a program used to join together several object files into one large object file. Intel 8085 8bit microprocessor shrimati indira gandhi.
