ATMEGA644P-20MQ Product Details
ATMEGA644P-20MQ Overview
Packaged in a 44-VFQFN Exposed Pad format, this MCU is available in a compact size. There are 32 I/Os on the Microcontroller. It is important to note that the Microcontroller has a Surface Mount mounting type. 8-Bit core is the basis for this Microcontroller. This program has a type of memory called FLASH for this MCU's program memory. Temperatures in this range are operated by this Microcontroller. The AVR® ATmega series includes this electrical component. There is 64KB 32K x 16 bytes of program memory in MCU, which corresponds to the size of the program. With a AVR Core processor, MCU is equipped with the latest technology available. This is a MICROCONTROLLER, RISC uPs/uCs/Peripheral IC. During the manufacturing process, 44 terminations were applied to the IC chip. 8-bits are used in Microcontroller. The MCU chip's supply output is 5V volts. Currently, MCU chip has NO DMA channels. 64kB memory size belongs to the Chip part. Alternatives can be found by looking at the base part number ATMEGA644P. In the case of 20MHz frequency operation, it can perform efficiently. There are YES PWM channels on the device. The chip has 44 pins. The clock has 3 timers/counters to keep track of the time. There is a FLASH memory feature on this equipment. With AVR core architecture, it offers high performance. A total of 32 programmable I/Os are available on this board. As a few examples, there are additional features like OPERATES AT 2.7 V MIN @ 10 MHZ that are available in the software.
