- 67. There are a lot of applications of Microprocessor in general life. Some of the applications are given below: Mobile Phones Digital Watches Washing Machine Computer Lighting Control Traffic Control LAPTOP Modems Power Stations Television CD Player Multimeter CRO Wave generator More applications in medical
- 68. Coffee Makers A coffee maker’s microprocessor executes its programming to consistently and correctly deliver a precise volume of water at an exact temperature perfect for brewing coffee. Remote controls The first TV remote controls used a beam of light to conduct basic functions: TV on/off, change channels, and mute. Microprocessors enhance the remote control with a multitude of pre-programmed options such as: sleep timer, last/previous, TV settings, guide, etc. Remote controls are also designed to work with a specific TV, but microprocessors have made the universal remote possible.
- 69. Dishwashers Modern dishwashers use microprocessors to increase their functionality. An increased number of options has led to specific types of run cycles. Options including the mixture of soap and water, water distribution, cleaning intensity, timing, and drying temperature. Watches Microprocessors enhanced the wristwatch from keeping time to a multi-functional machine. Microprocessor- based watches can sync with smartphones, download applications, read GPS coordinates, act as an alarm clock or timer, and sense temperature. Further, they add to the Millennial’s culture of health by tracking exercise, diet, and cardiovascular health.
- 70. Central Heating System The microprocessor in a central heating system interprets the measurements taken from the temperature sensors. Heating has become more exact through the constant regulation of climate control. Microprocessors have increased efficiency by measuring and minimizing energy output. Security Systems Security systems run throughout the house via a myriad of systems (motion sensors, locks, cameras, alarms) to protect from home invasion. The microprocessor at the central hub consistently processes the data being sent and waits for an “emergency” code. Security can be linked and monitored by computer or smartphone, assuring optimum safety.
- 71. Microwaves Sophisticated microprocessors expand the microwaves daily use. Now, they reheat according to food, weight, and desired temperature. Pre-programmed options remove the guesswork for defrosting and heating times. Microprocessors offer temperature consistency and remove hot spots. Car remote People are accustomed to unlocking and locking their vehicles through the use of a car remote. The car remote functions through a microprocessor allowing it to: locate, lock from a distance, open the trunk, and start the vehicle. High-end cars are now offering an option to connect directly to a smartphone, eliminating the need for a car remote and consolidating functions to one device.
- 72. Motorcycle Helmets Using an array of cameras, sensors, and microprocessors, helmets can communicate with the motorcycle to create an innovative heads-up display (HUD) in the visor. The Skully AR-1 telemetry helmet has been binding technology with safety to minimize accidents.
- 73. The availability of low cost, low power and small weight, computing capability makes it useful in different applications. Now a days, a microprocessor based systems are used in instructions, automatic testing product, speed control of motors, traffic light control , light control of furnaces etc. Some of the important areas are mentioned below:
- 74. Instrumentation: it is very useful in the field of instrumentation. Frequency counters, function generators, frequency synthesizers, spectrum analyses and many other instruments are available, when microprocessors are used as controller. It is also used in medical instrumentation Control: Microprocessor based controllers are available in home appliances, such as microwave oven, washing machine etc., microprocessors are being used in controlling various parameters like speed, pressure, temperature etc. These are used with the help of suitable transduction.
- 75. Communication: Microprocessors are being used in a wide range of communication equipments. In telephone industry, these are used in digital telephone sets. Telephone exchanges and modem etc. The use of microprocessor in television, satellite communication have made teleconferencing possible. Railway reservation and air reservation system also uses this technology. LAN and WAN for communication of vertical information through computer network. Office Automation and Publication: Microprocessor based micro computer with software packages has changed the office environment. Microprocessors based systems are being used for word processing, spread sheet operations, storage etc. The microprocessor has revolutionize the publication technology.

- 77. Altera AMD ARM ATMEL FAIRCHILD SEMICONDUCTOR FREESCALE SEMICONDUCTOR FUJITSU HITACHI RENESAS ELECTRONICS TOSHIBA WESTERN DIGITAL ZILOG NATIONAL SEMICONDUCTORS XILINX
- 78. Features: It is a programmable device. It has 24 I/O programmable pins like PA,PB,PC (3-8 pins). T T L compatible. Improved dc driving capability
- 80. Data bus(D0-D7):These are 8-bit bi-directional buses, connected to 8085 data bus for transferring data. CS: This is Active Low signal. When it is low, then data is transfer from 8085. Read: This is Active Low signal, when it is Low read operation will be start. Write: This is Active Low signal, when it is Low Write operation will be start.
- 82. RESET: This is used to reset the device. That means clear control registers. PA0-PA7:It is the 8-bit bi-directional I/O pins used to send the data to peripheral or or to receive the data from peripheral. PB0-PB7:Similar to PA PC0-PC7:This is also 8-bit bidirectional I/O pins. These lines are divided into two groups. 1. PC0 to PC3(Lower Groups) 2. PC4 to PC7 (Higher groups) These two groups working in separately using 4 data’s.
