ATMEGA328-AU Overview


Due to the benefits of saving space, it is available in the 32-TQFP package. In this case, it is mounted using the method of Surface Mount. A package of Tray contains it. AVR core processor is present on the device. During work, the temperature should remain at -40°C~85°C TA. Its type of program memory is FLASH. It has a number of 23I/Os. It has a base part number of ATMEGA328 that can be used to find other components that are comparable. The position of the device is QUAD at terminal. This circuit consists of 32 terminationals. The AVR? ATmega series includes this electrical component. As a result of the 5V supply voltage, high efficiency is possible. The gadget has MICROCONTROLLER, RISC for its uPs, uC, and peripheral ICs. The structure is constructed from 32 pins. This mount is done in accordance with the method of Surface Mount. This is a component included in Microcontrollers. In the device, there is a memory capacity of 32kB which may be used to store programs and data. There is 2/5V power source in this device. When working at a frequency of 20MHz it is able to achieve excellent efficiency. It appears that there are 3 timers/counters in use. During normal operation, the supply voltage (Vsup) should be kept above 4.5V. There is an oscillator type Internal used in this circuit.
