ATMEGA644P-20MU Overview


The package has a 44-VFQFN Exposed Pad shape. A total of 32 I/Os are on the Microcontroller. Using the Mounting Type Surface Mount, the MCU is mounted on PCB. Microcontroller is based on the 8-Bit core architecture. The type of memory that the program uses is FLASH. Temperatures in this range are operated by this Microcontroller. AVR® ATmega series components belong to this electrical component. There is 64KB 32K x 16 bytes of program memory in MCU, which corresponds to the size of the program. Powered by a AVR Core processor. The IC chip fits into the MICROCONTROLLER, RISC uPs/uCs/Peripheral ICs category. IC Chip 44 has 44 terminations. 8-bits are used in Microcontroller. This Microcontroller chip is powered by 5V volts. The Microcontroller chip has NO DMA channels. 64kB is the size of the memory in the IC part. The base part number ATMEGA644P provides alternatives. Performing well when operated at frequency 20MHz can be achieved. On the chip, 44 pins are accessible. In total, it has 3 timers and counters in it. The ADC channel count on this device totals up to 8 channels. The device uses 6 PWM channels. An 1-channel PWM controller is used by the device.
