ATXMEGA64A3U-AU Product Details

ATXMEGA64A3U-AU Overview


The package is 64-TQFP-shaped. There are 50 I/Os. In the case of the IC chip, the type of mounting is Surface Mount. Microcontroller is based on the 8/16-Bit core architecture. The type of program memory it uses is FLASH. Temperatures in the range of -40°C~85°C TA are operated by this Microcontroller. It is part of the AVR® XMEGA® A3U series of electrical components. Having a size of 64KB 32K x 16, Microcontroller has a program memory of X bytes. A AVR Core Processor is at the core of this Microcontroller. This device belongs to the MICROCONTROLLER, RISC uPs/uCs/Peripheral ICs category. IC Chip 64 has 64 terminations. 16-bits are used for its size. IC Chip has 3V volt supply outputs. With YES DMA channels, Microcontroller chip can handle large data transfers. 64kB is the size of the memory in the IC part. Using the base part number ATXMEGA64, you will be able to find alternatives for the part. Using a 32MHz frequency, this electronic part can perform efficiently. Devices work in YES PWM channels. On the chip, 64 pins are accessible. In total, there are 7 timers/counters on the device. The pin count is 64. There is an embedded the AVR RISC CPU family inside the device, which makes it a powerful device. In addition to the above, there are other features such as OPERATES AT 1.8 V MINIMUM SUPPLY AT 12 MHZ, to name but a few. The ADC channel count on this device totals up to 16 channels. In order for the device to function, it uses 22 PWM channels.
