A wide selection of microcontrollers from the AVR family
Our store's offer includes many different systems from the AVR family by Microchip. It is a family of 8-bit microcontrollers based on the Harvard RISC architecture. On the one hand, these microcontrollers are very simple to implement - many of the AVR family systems only need power supply (5 V or 3.3 V) to operate. These microcontrollers often have a built-in RC oscillator , which allows the generation of a clock waveform to clock the core. Additionally, AVR systems also have built-in RAM and program memory , as well as various optional peripherals . Thanks to such a high degree of integration, a microcontroller alone is often enough to operate the device. The AVR microcontroller is one of the most frequently purchased elements in our store.
AVR - Systems available in housings for various types of installation
Our store offers microcontrollers from the AVR family from Microchip in a wide range of different housings. Through-hole mounting systems (THT) are available, ideal for use, e.g. on breadboards, as well as simpler, larger PCBs and in surface-mount housings (SMD), often with a larger number of pins, but whose assembly is a little more complicated. complicated due to the smaller size of the legs. THT elements have from 8 to 40 pins, and in SMD housings from 8 to 64 pins.
A wide selection of systems with various possibilities
The AVR family is divided into two groups of systems - ATtiny and ATmega . These microcontrollers differ in the number of peripherals and the capacity of program memory and RAM. The ATtiny series systems generally lack interfaces such as a hardware serial port, have only one interrupt and are equipped with a much smaller amount of RAM and program memory. In turn, ATmega microcontrollers have one or more UART ports, two interrupts (or more) and a significantly larger amount of RAM. Additionally, ATtiny systems have a small to medium number of pins - GPIO - and ATmega systems have a medium to large number. Systems from both series of the AVR family are available in our store.
Various peripherals in AVR systems
The microcontroller consists of a central processing unit - CPU - RAM, program memory (usually ROM or Flash, currently less often EEPROM) and extensive input-output systems. In the AVR family, as well as in other similar microcontrollers, it is the wide selection of peripheral systems that gives them their strength in electronic systems. The AVR microcontrollers offered by our store are equipped with a very diverse set of digital and analog input and output systems. In addition to general-purpose digital I/O lines (GPIO), AVR systems also include other digital serial interfaces, such as UART, I2C or SPI, as well as USB (as a device). Analog inputs are also available - the system has a built-in analog-to-digital converter (ADC) with an input multiplexer. These microcontrollers also have built-in timers with the ability to generate waveforms with variable duty cycle (PWM), counters, etc.
