Various types of microcontrollers are used in automotive applications.

The use of different types of microcontrollers to handle various operations such as machining needs, automobiles, electrical systems, and applications is growing rapidly. The use of microcontrollers can be found in various large equipment, up to small devices, such as mainframes, air conditioners, aviation navigation systems, digital watches, pocket computers, and cell phones. In particular, the presence of various microcontrollers in cars plays a vital role, which is evidenced by the presence of 25-35 ECUs (electronic control units) in a typical Ford car. The range of the ECU in luxury cars, such as the BMW 7 series, is from 60 to 65. Microcontrollers control the functions of the ECU, such as seats, power windows, brakes, steering, tail lights, and headlights. This article discusses various microcontrollers used in cars, as well as their applications.

Different types of microcontrollers
A microcontroller is a small chip used as an embedded system. Some microcontrollers may require operation with a clock frequency and four-bit expressions, which typically include:

8-bit or 16-bit microprocessor.
Flash memory and PPZU
Serial and parallel input-output
Signal generators and timers
Analog-to-digital and digital-to-analog conversion

Together with other electronic control units in automotive electronics, the use of various microcontrollers is increasing. Basically, in cars, different types of microcontrollers are used: AVR microcontroller, 8051 microcontrollers, PIC microcontroller, etc. These types of microcontrollers require a chip that includes a CPU, RAM (random access memory), program memory, and programmable inputs/outputs and outputs. Modern microcontrollers improve the management of the car fleet. This range varies from 8-bit to 32-bit Harvard architecture with inexpensive processors, high performance, and efficient data storage in memory.

Various microcontrollers are used in the automotive industry.
Different microcontrollers used in the car can interact with each other using multiplexing. These microcontrollers can control connected systems individually, using the bus to communicate with other networks when they are called upon to perform a function. A combination of several connected networks includes CAN (controller local area networks). Existing networks of controller zones allow complex interactions that include sensor systems, vehicle speed, interaction with external rain, vehicle temperature with operating commands for air conditioner maintenance, multimedia systems, and audiovisual and brake mechanisms.

Communication in cars, established by different microcontrollers, is managed by both fail-safe systems and automotive fail-safe systems, in which microcontrollers can be used not only to respond to incidents and malfunctions that occur in the car (interference from the anti-lock braking system, broken throttle, and headlights) but also to duplicate as secondary blocks, check the main microcontroller in case of failure of the microcontroller itself. An example of fault tolerance is the situation when car tires slide on a snow-covered road. The incident not only activated the reaction of the car driver but also the incident was detected by the microcontroller of the sensor, which then activates the anti-time braking system when the car driver presses the brake.

 Infineon tri-core microcontroller
Tri-core is a 32-bit microcontroller that is used in more than 50 car brands, which means that every second vehicle designed today includes a Tri-core microcontroller. It is responsible for the lowest possible exhaust gas emissions and fuel consumption. Tri-core microcontrollers are used in gearboxes for injection control, and central control units for ignition of thermal engines: gradually they are also used in electric and hybrid drives of vehicles.

Atmel AVR microcontroller.
Atmel AVR (Alf-Egil-Bogen-Vegard-Wollan-RISK) microcontrollers distribute power, performance, and flexibility in automotive applications. This microcontroller is based on Harvard architecture. Thus, the device works very quickly with a reduced number of instructions at the machine level. AVR microcontrollers are divided into three types: Tiny AVR, Mega AVR, and Xmega AVR. The main features of AVR microcontrollers compared to other microcontrollers include a built-in ADC, 6 standby modes, serial data transfer, an internal generator, etc.

PIC microcontroller
The shortened form of the peripheral interface microcontroller is PIC. It is programmed and controlled in such a way that it performs several tasks and controls the generation line. These microcontrollers are used in many applications, such as smartphones, automobiles, audio accessories, and medical devices. PIC microcontrollers from PIC16F84 to PIC16C84 are currently available on the market and are affordable flash microcontrollers. Where microcontrollers PIC18F458 and PIC18F258 are widely used in cars.

Renesas microcontroller
Renesas is the newest family of automotive microcontrollers that provide high performance and low power consumption for a wide range of devices. This microcontroller offers built-in safety features and functional safety for advanced automotive applications. These microcontrollers offer the world's most useful family of microcontrollers. For example, the RX family offers different types of devices with memory options from 32 KB of flash memory / 4 KB of RAM to an incredible 8 flash memory / 512 KB of RAM. This RX family microcontroller uses an advanced 32-bit Harvard CISC architecture to achieve very high performance.

8051 Microcontroller
The 8051 microcontroller is a 40-pin microcontroller and is based on the Harvard architecture, in which program memory and data memory are different. This microcontroller is used in a large number of machines, such as cars because it can be easily integrated into the machine.

8-bit microcontrollers are mainly used.
A high degree of integration and a low decision-making factor about electromagnetic interference
The design cycle is 3-4 years.
Thus, various types of modern microcontrollers have marked revolutionary changes in all aspects of automotive design and production processes due to their adaptability and flexibility.
