ATMEGA644-20AUR Overview
Due to its space-saving qualities, it is available in the 44-TQFP package. The way of Surface Mount is used to mount it. In the package Tape & Reel (TR), it is included. There is a AVR as core processor in this device. Maintain a temperature of -40°C~85°C TA while working. The type of memory it uses is FLASH. There are 32 I/Os on the board. A comparable component can be found by using the base part number ATMEGA644. The terminals of this device are located at QUAD. 44 terminationals are present. An electrical component such as this is included in the series AVR? ATmega. By using a 5V voltage supply, high efficiency is possible. As for the uPs/uCs/peripheral ICs, this gadget has MICROCONTROLLER, RISC. It is constructed using 44 pins. A method of mounting is used, which is Surface Mount. Subcategory Microcontrollers includes this component. It is possible to store programs and data on the devices, as they have a memory size of 64kB. The maximum supply current is set at 9mA. This device achieves excellent efficiency at frequencies of 20MHz. There are currently 3 timers/counters set up on the system. ALSO OPERATES AT 2.7V SUPPLY AT 10 MHZ also belongs to it. In order to maintain normal operation, Vsup must be above 4.5V. Using a Internal oscillator type, it works well.
