ATMEGA645A-MUR Overview


A space-saving advantage is that it is included in the 64-VFQFN Exposed Pad package. A Surface Mount mounting method is used. There is a Tape & Reel (TR) package available for it. AVR core processor is present on the device. Maintain a temperature of -40°C~85°C TA while working. It has a type of program memory of FLASH. It has a number of 54I/Os. A component with the same part number as ATMEGA645A can be compared to other similar components. The terminals of this device are located at QUAD. It has 64 terminationals. The electrical component is part of the series AVR? ATmega. Because of the 5V voltage of the supply, high efficiency can be achieved. The gadget has MICROCONTROLLER, RISC for its uPs, uC, and peripheral ICs. It is constructed using 64 pins. The mounting of this device is carried out following the method of Surface Mount. Subcategory Microcontrollers includes this component. Data and programs can be stored on the devices with a memory size of 64kB. In this case, 12mA represents the maximum current supply. There is a source of power of 2/5V that powers this device. This device works well at 16MHz frequency when it is operating at a high rate of efficiency. There are currently 3 timers/counters set up on the system. In addition, it is also capable of having the property ALSO OPERATES AT 2.7 V MINIMUM SUPPLY AT 8 MHZ AND 1.8 V MINIMUM SUPPLY AT 4 MHZ. Normal operation requires a supply voltage (Vsup) that is higher than 4.5V. Using a Internal oscillator type, it works well.
