ATMEGA645A-AUR Overview


A space-saving advantage is that it is included in the 64-TQFP package. The way of Surface Mount is used to mount it. There is a Tape & Reel (TR) package available for it. AVR core processor is present on the device. When working, it is recommended that the temperature be kept at -40°C~85°C TA. It has a type of program memory of FLASH. There are 54 I/Os on it. In order to find similar components, it has a base part number of ATMEGA645A. QUAD is the position of its terminals on the board. There are a total of 64 terminations in it. AVR? ATmega is the series number of this electrical component. Because the supply voltage is 5V, high efficiency can be achieved. UPs/UCS/Peripheral ICs of this gadget are MICROCONTROLLER, RISC in order to monitor their performance. The structure is composed of 64 pins. This mount is done in accordance with the method of Surface Mount. This is a component included in Microcontrollers. The devices have a maximum memory size of 64kB that can be used to store programs and data. It is important to note that the maximum supply current is 12mA. Power is provided by a 2/5V source. This device works well at 16MHz frequency when it is operating at a high rate of efficiency. In total, there are 3 timers and counters. The property ALSO OPERATES AT 2.7 V MINIMUM SUPPLY AT 8 MHZ AND 1.8 V MINIMUM SUPPLY AT 4 MHZ is also present in it. In order to ensure normal operation, the supply voltage (Vsup) must remain above 4.5V. Using an oscillator type Internal, it operates.
