ATMEGA644-20PU Overview


There is an option to purchase it in the 40-DIP (0.600, 15.24mm) package, which saves space. Through Hole is used for mounting. This item can be found in package Tube. There is a AVR as core processor in this device. It is important to keep the temperature at -40°C~85°C TA while working. There is FLASH program memory in it. A total of 32 I/Os are present. In order to find similar components, it has a base part number of ATMEGA644. DUAL is the location of its terminals. A 40 termination is contained within it. AVR? ATmega is the series number of this electrical component. The supply voltage of 5V allows for high efficiency. The gadget has MICROCONTROLLER, RISC as its uPs/uCs/peripheral IC. A total of 40 pins are required to construct this device. As a result, it is mounted in accordance with Through Hole. In the subcategory of Microcontrollers, this component is included. A device with a memory size of 64kB can store programs and data. It should be noted that 9mA represents the maximum supply current. The system is highly efficient when working at a frequency of 20MHz. The number of timers and counters is 3. In order to ensure normal operation, the supply voltage (Vsup) must remain above 4.5V. The oscillator type Internal is used to operate the device.
