ATMEGA2561V-8AU Product Details

ATMEGA2561V-8AU Overview


Packaged in a 64-TQFP format, this MCU is available in a compact size. There are 54 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 256KB 128K 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, 64 terminations were applied to the IC chip. 8-bits are used in Microcontroller. The MCU chip's supply output is 3V volts. Currently, MCU chip has NO DMA channels. 256kB memory size belongs to the Chip part. Alternatives can be found by looking at the base part number ATMEGA2561. In the case of 8MHz frequency operation, it can perform efficiently. There are YES PWM channels on the device. The chip has 64 pins. The clock has 6 timers/counters to keep track of the time. 64 pins are counted on this board. This device is embedded with a AVR RISC processor family, which is a powerful and efficient CPU. As a few examples, there are additional features like ALSO OPERATES AT 1.8V MINIMUM SUPPLY AT 2 MHZ that are available in the software. A total of 8 ADC channels are present in this device. There are 10 PWM channels that are used by the device. An 1-channel PWM controller is used by the device.
