ATMEGA644P-20AUR Overview


There is an option to purchase it in the 44-TQFP package, which saves space. The way of mounting it is Surface Mount. In the package Tape & Reel (TR), it is included. With a processor of AVR cores, the device is powered. When working, it is recommended that the temperature be kept at -40°C~85°C TA. Memory type FLASH is used for program memory. The device has 32 I/Os. To find comparable components, use the ATMEGA644P base part number. QUAD is the position of its terminals on the board. 44 terminations are present in it. It is a member of the AVR? ATmega series of electrical components. The 5V supply voltage enables high efficiency. The gadget has MICROCONTROLLER, RISC as its uPs/uCs/peripheral IC. A total of 44 pins are used in its construction. Mounting is performed in accordance with Surface Mount. In the subcategory of Microcontrollers, this component is included. Data and programs can be stored on the devices with a memory size of 64kB. The maximum supply current is 9mA. Using a frequency of 20MHz, it is very efficient. There are currently 3 timers/counters set up on the system. There is also the property of OPERATES AT 2.7 V MIMIMUM SUPPLY AT 10 MHZ. For normal operation, the supply voltage (Vsup) should be kept above 4.5V. An oscillator type Internal is required for it to work.
