PC microprocessors are always at least 32-bit and commonly now 64-bit. Most people start with a DIL (Dual In Line) 28-pin chip like the ATmega328 or the 40-pin ATmega16 or ATmega32. AVRs are available with 8-pins to 100-pins, although anything 64-pin or over is surface mount only.

If you tried this with a microprocessor, bang!ĪVR microntrollers come in different packages,some designed for through-hole mounting and some surface mount.

On that motherboard is a microprocessor (Intel, AMD chips) that provides the intelligence, RAM and EEPROM memories and interfaces to rest of system, like serial ports (mostly USB ports now), disk drives and display interfaces.Ī microcontroller has all or most of these features built-in to a single chip, so it doesn’t need a motherboard and many components, LEDs for example, can be connected directly to the AVR. The easiest way of thinking about it is to compare a microcontroller with your PC, which has a motherboard in it. In applications where voltage impulses, spikes, and transients are a significant concern, you should also consider Transient Suppression as a critical feature.An AVR microcontroller is a type of device manufactured by Atmel, which has particular benefits over other common chips, but first what is a microcontroller? The five characteristics listed above are critical for an automatic voltage regulator to perform reliably in demanding applications. Typically, automatic voltage regulators function in circuits where voltage regulation can not be achieved by changing the size of the conductor. The primary job of an automatic voltage regulator is to make voltage levels more accurate, but what is the optimal accuracy level for your application? Voltage accuracy is dependent on the critical load requirement. To prevent instability, the regulator's speed of response must be designed to work with the electronic power supplies used in much of today's equipment. High performing automatic voltage regulators should be able to handle loads with high starting currents, all power factors, and high crest factors. Voltage regulation solutions must be compatible with the specified load to ensure its operation and to avoid interfering with the operation of other loads connected to the same power source. Ideally, your automatic voltage regulator would avoid all of this if it had low impedance. Interaction between the load current and source impedance can cause low voltage, harmonic distortion, and voltage unbalance. The goal of an automatic voltage regulator is to achieve low impedance. Impedance is the resistance of a component to the flow of electrical current, measured in ohms. It also allows the automatic voltage regulator to be more configurable to all buck or boost, giving it maximum voltage correction for extreme cases. This feature allows for more low correction, rather than high correction. The input voltage range should be broad and shifted because line voltages drop more than they increase. The first step in selecting the best automatic voltage regulator is specifying your input voltage range. This requirement eliminates three-phase unbalance problems and minimizes voltage deviations. Regardless of these potential obstacles, voltage regulation must be selectable to an accuracy of ☑%. Several factors can affect voltage regulation, including wire and cable size and type, transformer reactance and cables, motor starter, circuit design, and power factor. Optimal voltage regulation is achieved when the value of voltage is equivalent to all electrical equipment loads.
