Bus Structure & Control Signals of 8085 Microprocessor (Part 1) Microprocessor (Part 1) The 8085 microprocessor uses a bus structure to connect its internal parts to external memory and peripheral devices. It is essential to know the bus architecture in order to understand how the microprocessor communicate and performs instructions. The bus structure of the […]

8085 Microprocessor Architecture The 8085 is called an 8-bit processor since its data length and data bus width is 8-bits. It has an addressing capability of 16 bits, that is, it can address 216 = 64 KB of memory (1 KB = 1024 bytes). 8085 microprocessors generally available in 40 pin IC package and uses

8085 Microprocessor Pin Diagram Intel 8085 has 40 pins, operated at 3 MHz clock frequency, and requires +5V for power supply. The 8085 is available with 40 pins as a Dual in-Line Package (DIP). The signals can be classified into Seven (7) categories: Power Supply and Frequency Signals Data Bus and Address Bus Control and

Memory Unit of Microprocessor Memory Unit is an integral part of any microprocessor system. Its primary purpose is to hold program and data. The main objective of the memory unit design is to enable it to operate at a speed close to that of the processor. Advanced technology supports the design of high-speed memory, whereas

Origin & Timeline Of Microprocessor Evolution Origin of Microprocessors Microprocessor evolution started with the earlier mechanical calculating devices, in the 1930s. These devices used mechanical relays, later on in the 1950s, these devices were replaced by vacuum tubes. The vacuum tubes were quickly replaced by transistors. The breakthrough in transistor technology led to the introduction

Microprocessors Vs Microcontrollers Features and Basic Differences Features of a Microprocessor Microprocessors are the integrated circuits at the core of every modern computer and electrical gadget.
