ATMEGA644P-20AU Overview
To save space, it is included in the 44-TQFP package. It is mounted using the way of Surface Mount. Package Tray contains it. The device has a AVR core processor. 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 32 I/Os on the board. It has a base part number of ATMEGA644P that can be used to find other components that are comparable. The terminals of this device are set to QUAD. In this case, there are 44 terminationals. An electrical component such as this is included in the series AVR? ATmega. By using a 5V voltage supply, high efficiency is possible. Storage of data is performed using memory type EEPROM, FLASH. This gadget has MICROCONTROLLER, RISC as its uPs/uCs/Peripheral IC. A total of 44 pins are required to construct this device. A method of mounting is used, which is Surface Mount. Subcategory Microcontrollers includes this component. In the device, there is a memory capacity of 64kB which may be used to store programs and data. Supply current is maximum at 9mA. Using a frequency of 20MHz, it is very efficient. A total of 3 timers/counters have been set up. In order to maintain normal operation, the supply voltage (Vsup) should be maintained above 4.5V. An oscillator type Internal is required for it to work.
