ATMEGA644-20PU Overview


There is a 40-DIP (0.600, 15.24mm) package available. The MCU has 32 I/O ports. The Microcontroller has a mounting type of Through Hole, which indicates that it is mounted conveniently. The 8-Bit core is the core of the MCU. There is a FLASH type of memory for its program. The temperature range that this Microcontroller operates at is -40°C~85°C TA. An electrical component of this type belongs to the AVR® ATmega series. Having a size of 64KB 32K x 16, Microcontroller has a program memory of X bytes. There's a AVR Core Processor inside. The device belongs to MICROCONTROLLER, RISC uPs/uCs/Peripheral ICs Type. This chip has a total of 40 terminations on MCU chip. You get a 8-bit size. Input voltage for the chip is 5V volts. The Microcontroller chip has NO DMA channels. 64kB is the memory size of the part. Alternatives can be found by searching through the base part number ATMEGA644 to find them. 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 to access the 40 pins on the chip. There are 3 timers/counters in this device. The ADC channel count on this device totals up to 8 channels. A total of 6 PWM channels are used by the device. 1 channels of I2C have been incorporated into the design of the part.
