ATMEGA644-20MUR Product Details

ATMEGA644-20MUR Overview


A 44-VFQFN Exposed Pad package is included. In total, it has 32 inputs and outputs. This Microcontroller is mounted using the Surface Mount mounting type. Powered by the 8-Bit core, it offers a wide range of capabilities. The type of memory that the program uses is FLASH. The temperature range of this Microcontroller is within the range of -40°C~85°C TA. AVR® ATmega series components belong to this electrical component. Its program memory size is 64KB 32K x 16. There is a AVR Core Processor inside MCU that provides this device with its power. MICROCONTROLLER, RISC uPs, uCs, and peripheral ICs make up the Microcontroller. Microcontroller is known that the chip has 44 terminations in total. The part works on a 8-bit basis. An output voltage of 5V volts is available for this Microcontroller chip. The Microcontroller chip has NO DMA channels. 64kB memory size belongs to the part. ATMEGA644 is the base part number that you can use to find alternatives. A good performance can be achieved at a frequency of 20MHz, as long as it is operated at a low power consumption. In order for the device to work with the motor, it utilizes the PWM channel YES. On the chip, there are 44 pins that are accessible. A total of 3 timers/counters are included in the package. Devices based on the AVR RISC series of CPUs are embedded in the device. There's built-in FLASH memory in the equipment. It is built on a AVR core architecture. This 8 Programmable I/O section allows you to program the device in many different ways depending on what you need. As a few examples, there are additional features like ALSO OPERATES AT 2.7V SUPPLY AT 10 MHZ that are available in the software.
