ATMEGA644P-20AQ Overview
Due to its space-saving qualities, it is available in the 44-TQFP package. This is mounted using the Surface Mount method. Package Tray contains it. Devices with AVR core processors are available. When working, the temperature should be kept at -40°C~105°C TA. The type of memory in which this program is stored is FLASH. The device has 32 I/Os. It has a part number of ATMEGA644P that can be used to locate similar components. At QUAD, its terminals are located. A 44 termination is contained within it. AVR? ATmega is the series number of this electrical component. High efficiency is possible due to the 5V supply voltage. MICROCONTROLLER, RISC is the uPs/uCs/Peripheral IC chip in this gadget. 44 pins are used to construct it. The mounting of this device is carried out following the method of Surface Mount. Using the devices' 64kB memory size, you can store programs and data. Using a frequency of 20MHz, it is very efficient. A total of 3 timers/counters have been set up. The property OPERATES AT 2.7 V MIN @ 10 MHZ is also present in it. Normally, the supply voltage (Vsup) should remain above 4.5V. Using an oscillator type Internal, it operates.
