ATMEGA645A-AU Overview
For space savings, it is available in the 64-TQFP package. Using Surface Mount, it is mounted. You can find it in the package of Tray. The device runs in AVR core processor. When working, the temperature should be kept at -40°C~85°C TA. FLASH is its program memory type. It has a number of 54I/Os. Based on its base part number of ATMEGA645A, other similarly-sized components can be found. A QUAD position is assigned to its terminals. This circuit consists of 64 terminationals. This electrical component is part of the AVR? ATmega series. Because of the 5V voltage of the supply, high efficiency can be achieved. MICROCONTROLLER, RISC is the uPs/uCs/Peripheral IC chip in this gadget. For its construction, 64 pins are used. Mounting is performed in accordance with Surface Mount. In the subcategory of Microcontrollers, this component is included. It is possible to store programs and data on the devices, as they have a memory size of 64kB. Power is provided by a source of 2/5V. This device achieves excellent efficiency at frequencies of 16MHz. It appears that there are 3 timers/counters in use. Using an oscillator type Internal, it operates.
