ATMEGA644P-20MUR Product Details

ATMEGA644P-20MUR Overview


The package is 44-VFQFN Exposed Pad-shaped. There are 32 I/Os. In the case of the IC chip, the type of mounting is Surface Mount. Microcontroller is based on the 8-Bit core architecture. The type of program memory it uses is FLASH. Temperatures in the range of -40°C~85°C TA are operated by this Microcontroller. It is part of the AVR® ATmega series of electrical components. Having a size of 64KB 32K x 16, Microcontroller has a program memory of X bytes. A AVR Core Processor is at the core of this Microcontroller. This device belongs to the MICROCONTROLLER, RISC uPs/uCs/Peripheral ICs category. IC Chip 44 has 44 terminations. 8-bits are used for its size. IC Chip has 5V volt supply outputs. With NO DMA channels, Microcontroller chip can handle large data transfers. 64kB is the size of the memory in the IC part. Using the base part number ATMEGA644P, you will be able to find alternatives for the part. Using a 20MHz frequency, this electronic part can perform efficiently. Devices work in YES PWM channels. There is an embedded the AVR RISC CPU family inside the device, which makes it a powerful device. In addition to the above, there are other features such as OPERATES AT 2.7 V MIMIMUM SUPPLY AT 10 MHZ, to name but a few.
