ATMEGA644P-20MQ Overview
It is available in the 44-VFQFN Exposed Pad package for the benefit of saving space. This is mounted using the Surface Mount method. There is a Tray package available for it. A AVR core processor powers the device. Maintain a temperature of -40°C~105°C TA while working. It has a type of program memory of FLASH. The device has 32 I/Os. In order to find similar components, it has a base part number of ATMEGA644P. QUAD is the location of its terminals. There are a total of 44 terminations in it. Part of the AVR? ATmega series, this electrical component is used in a variety of applications. Because of the 5V voltage of the supply, high efficiency can be achieved. UPs/UCS/Peripheral ICs of this gadget are MICROCONTROLLER, RISC in order to monitor their performance. It is constructed with 44 pins. As a result, it is mounted in accordance with Surface Mount. The devices have a memory size of 64kB that can be used to store programs and data. The system is highly efficient when working at a frequency of 20MHz. The number of timers and counters is 3. There is also the property of OPERATES AT 2.7 V MIN @ 10 MHZ. Normal operation requires a supply voltage (Vsup) that is higher than 4.5V. Using an oscillator type Internal, it operates.
