ATMEGA645A-MU Overview
There is a 64-VFQFN Exposed Pad package available to save space. Mounted using Surface Mount. In the package Tray, it is included. With a processor of AVR cores, the device is powered. During work, the temperature should remain at -40°C~85°C TA. Memory type FLASH is used for program memory. There are 54 I/Os on the board. To find comparable components, use the ATMEGA645A base part number. This device has terminals at QUAD. This circuit consists of 64 terminationals. It is a member of the AVR? ATmega series of electrical components. Because the supply voltage is 5V, high efficiency can be achieved. The gadget has MICROCONTROLLER, RISC as its uPs/uCs/peripheral IC. The structure is composed of 64 pins. The method of Surface Mount is used to mount it. Microcontrollers contains this component. The devices have a maximum memory size of 64kB that can be used to store programs and data. Supply current cannot exceed 12mA. Powered by a 2/5V source. At a frequency of 16MHz, it can achieve excellent efficiency. There are 3 timers/counters. 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. 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.
