ATMEGA644PA-PU Product Details

ATMEGA644PA-PU Overview


The package is in 40-DIP (0.600, 15.24mm) format. The MCU has 32 I/O ports. There is a mounting type Through Hole associated with this Microcontroller. This Microcontroller is based on the 8-Bit core. There is a memory type of FLASH in its program memory. The temperature range that this Microcontroller operates at is -40°C~85°C TA. The electrical component that you are looking at belongs to the AVR® ATmega series of components. Microcontroller has abundant program memory size of 64KB 32K x 16. The AVR Core Processor powers the device and is one of its key features. This Microcontroller belongs to the MICROCONTROLLER, RISC uPs/uCs/peripheral ICs type. During the manufacture of the IC chip, there is a number 40 of terminations. A 8-bit operation is performed by this part. A total of NO DMA channels are available on MCU chip. This MCU is implemented with 64kB memory. ATMEGA644PA serves as a base part number to find alternatives. It exhibits good efficiency when it operates at a frequency of 20MHz and it is able to operate at a high frequency. It is possible for the device to work with the motor using the PWM channel YES. It is possible to access the 40 pins on the chip through the 40 pins. It is equipped with 3 timers and counters. It consists of 40 pins. As far as the CPU is concerned, it is embedded with the the AVR RISC family of processors. There are a total of 8 channels for the ADC on this board, so it has a total of 8 channels. An 6-channel PWM controller is used by the device. In this device, there's an 1-channel PWM controller. A total of 2 serial I/Os are included in the electronic part. An external interrupt is included with the chip part, which consists of 3 interrupts. An entire Microcontroller chip has 3 bits.
