ATMEGA644-20AUR Product Details

ATMEGA644-20AUR Overview


Packaged in a 44-TQFP format. A total of 32 I/Os are on the Microcontroller. Surface Mount is the mounting type of the Microcontroller that is attached to the panel. This Microcontroller is based on a core called 8-Bit. The type of its program memory is FLASH. In this Microcontroller, temperature is controlled within the range -40°C~85°C TA. A AVR® ATmega series electrical component is used in this application. This program has a program memory of 64KB 32K x 16 bytes, which is the size of the program. With a AVR Core Processor, Microcontroller is fast and efficient. ICs for MICROCONTROLLER, RISC uPs/uCs/peripheral parts. There are 44 terminations on the IC chip, which means there are 44 terminations on the integrated circuit chip. In addition, MCU chip comes with a 8-bit size. Microcontroller chip has outputs of 5V volts. The system has NO channels for DMA communication. There is 64kB memory size assigned to the part. Alternatives can be found by searching through the base part number ATMEGA644 to find them. At a frequency of 20MHz, Microcontroller can operate efficiently. This MCU Chip uses YES PWM channels to operate. Chips have 44 pins. There are 3 timers/counters in this device. The AVR RISC CPU family is embedded in the device, so it can handle a wide range of operations. The equipment has a FLASH memory that is built in. It is equipped with a AVR core architecture which is integrated into it. As an example, one of the additional features that you can use is ALSO OPERATES AT 2.7V SUPPLY AT 10 MHZ.
