ATMEGA644PA-AU Overview
As a result, it is available in the 44-TQFP package. Mounted using Surface Mount. Package Tray contains it. With a processor of AVR cores, the device is powered. It is important to keep the temperature at -40°C~85°C TA while working. FLASH is its program memory type. A total of 32 I/Os are present. Other components that are comparable to it have the base part number ATMEGA644PA. At QUAD, its terminals are located. 44 terminationals are present. AVR? ATmega is the series number of this electrical component. In this gadget, MICROCONTROLLER, RISC is the device's uPs/uCs/Peripheral IC. 44 pins are used to construct it. The method of Surface Mount is used to mount it. The component is included in Microcontrollers. The devices have a maximum memory size of 64kB that can be used to store programs and data. Supply current is maximum at 9mA. Power comes from a source of 2/5V. Using a frequency of 20MHz, it is very efficient. There are currently 3 timers/counters set up on the system. Internal is the oscillator type it uses.
