ATXMEGA128A4U-AU Product Details

ATXMEGA128A4U-AU Overview


Packaged in a 44-TQFP format, this MCU is available in a compact size. There are 34 I/Os on the Microcontroller. It is important to note that the Microcontroller has a Surface Mount mounting type. 8/16-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® XMEGA® A4U series includes this electrical component. There is 128KB 64K 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. 16-bits are used in Microcontroller. The MCU chip's supply output is 3V volts. Currently, MCU chip has YES DMA channels. 128kB memory size belongs to the Chip part. Alternatives can be found by looking at the base part number ATXMEGA128. In the case of 32MHz frequency operation, it can perform efficiently. There are YES PWM channels on the device. The chip has 44 pins. The clock has 5 timers/counters to keep track of the time. 44 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 OPERATES AT 1.8 V MINIMUM SUPPLY AT 12 MHZ that are available in the software. A total of 12 ADC channels are present in this device. There are 16 PWM channels that are used by the device. An 2-channel PWM controller is used by the device.
