ATMEGA644PA-AUR Overview


For space savings, it is available in the 44-TQFP package. Surface Mount is the way to mount it. In the package Tape & Reel (TR), it is included. Device with AVR core processor issupported. It is important to keep the temperature at -40°C~85°C TA while working. FLASH has been assigned to it as a program memory. 32 I/Os have been provided by the device. Based on the ATMEGA644PA base part number, it can be compared with other components. The terminals of this device are located at QUAD. It has 44 terminationals. This electrical component is part of the AVR? ATmega series. This gadget has MICROCONTROLLER, RISC as its uPs/uCs/Peripheral IC. A total of 44 pins are used in its construction. According to Surface Mount, it is mounted. This component is a part of Microcontrollers. Data and programs may be stored on the devices which have a memory size of 64kB. It should be noted that 9mA represents the maximum supply current. There is a source of power of 2/5V that powers this device. Using a frequency of 20MHz, it is very efficient. There are currently 3 timers/counters set up on the system. In order to maintain normal operation, Vsup must be above 1.8V. Using oscillator type Internal makes it work.
