ATMEGA644P-20PU Overview


As a result, it is available in the 40-DIP (0.600, 15.24mm) package. The way of mounting it is Through Hole. Tube is the package that contains it. It is equipped with a AVR core processor. During work, the temperature should remain at -40°C~85°C TA. In terms of its program memory type, it is FLASH. It has a number of 32I/Os. A comparable component can be found by using the base part number ATMEGA644P. The position of the device is DUAL at terminal. In this case, there are 40 terminationals. The electrical component is part of the series AVR? ATmega. The supply voltage of 5V allows for high efficiency. uPs/uCs/Peripheral IC for this gadget is MICROCONTROLLER, RISC. A number of 40 pins are used to construct it. Based on the Through Hole method, it is mounted. The component is included in Microcontrollers. Using the devices' 64kB memory size, you can store programs and data. There is a maximum current supply of 9mA. This device works well at 20MHz frequency when it is operating at a high rate of efficiency. A total of 3 timers/counters are present. In order to maintain normal operation, Vsup must be above 4.5V. Using an oscillator type Internal, it operates.
