ATMEGA644P-20PQ Overview


Due to the benefits of saving space, it is available in the 44-TQFP package. A Surface Mount mounting method is used. It comes in a Tube package. With a processor of AVR cores, the device is powered. It is important to keep the temperature at -40°C~105°C TA while working. In terms of its program memory type, it is FLASH. The device has 32 I/Os. To find comparable components, use the ATMEGA644P base part number. A DUAL position is assigned to its terminals. As far as terminations are concerned, there are 40 terminations present. There are a number of electrical components in the AVR? ATmega series, including this one. By using a 5V voltage supply, high efficiency is possible. This gadget has MICROCONTROLLER, RISC as its uPs/uCs/Peripheral IC. A total of 40 pins are required to construct this device. It is mounted based on the method of Through Hole. A device with a memory size of 64kB can store programs and data. The system is highly efficient when working at a frequency of 20MHz. In total, there are 3 timers and counters. In addition, it is also capable of having the property OPERATES AT 2.7 V MIN @ 10 MHZ. A supply voltage (Vsup) above 4.5V is necessary for normal operation. There is an oscillator type Internal used in this circuit.
