ATMEGA328-PU Overview


There is a 28-DIP (0.300, 7.62mm) package available to save space. It is mounted using the way of Through Hole. Tube is the package that contains it. There is a AVR as core processor in this device. When working, the temperature should be kept at -40°C~85°C TA. Memory type FLASH is used for program memory. There are 23 I/Os on the board. It has a base part number of ATMEGA328 that can be used to find other components that are comparable. The terminals of this device are located at DUAL. Currently, it consists of 28 terminationals. AVR? ATmega is the series number of this electrical component. Because the supply voltage is 5V, high efficiency can be achieved. uPs/uCs/Peripheral IC for this gadget is MICROCONTROLLER, RISC. It is constructed using 28 pins. This mount is done in accordance with the method of Through Hole. This is a component included in Microcontrollers. Using the devices' 32kB memory size, you can store programs and data. A 2/5V source of power is being used to run it. It is highly efficient when it works at a frequency of 20MHz. A total of 3 timers/counters have been set up. During normal operation, the supply voltage (Vsup) should be kept above 4.5V. There is an oscillator type Internal used in this circuit.
