ATMEGA644A-PU Overview


There is a 40-DIP (0.600, 15.24mm) package available to save space. Through Hole is used for mounting. Package Tube contains it. A core processor of AVR is present in the device. When working, it is recommended that the temperature be kept at -40°C~85°C TA. FLASH has been assigned to it as a program memory. A total of 32 I/Os are available on this device. To find equivalent components, use its ATMEGA644A base part number. The position of the device is DUAL at terminal. This circuit consists of 40 terminationals. It is a member of the AVR? ATmega series of electrical components. As for the uPs/uCs/peripheral ICs, this gadget has MICROCONTROLLER, RISC. A number of 40 pins are used to construct it. A method of mounting is used, which is Through Hole. This component is a part of Microcontrollers. Data and programs can be stored on the devices with a memory size of 64kB. A maximum supply current of 9mA is set. There is a source of power of 2/5V that powers this device. This device achieves excellent efficiency at frequencies of 20MHz. 3 timers/counters are in use. The oscillator type Internal is used to operate the device.
