ATXMEGA256A3BU-MH Product Details
ATXMEGA256A3BU-MH Overview
In a 64-VFQFN Exposed Pad package, the MCU is available. 47 I/Os are available. The Microcontroller has a mounting type of Surface Mount, which indicates that it is mounted conveniently. The 8/16-Bit core is the core of the MCU. There is a FLASH type of memory for its program. There is a temperature range of -40°C~85°C TA that is operated by this Microcontroller. AVR® XMEGA® A3BU series components make up this electrical component. 256KB 128K x 16 is the size of its program memory. A AVR Core processor is used to power the device. This device falls under the MICROCONTROLLER, RISC uPs/uCs/Peripheral ICs category. 64 is the number of terminations on the IC chip that are present. This part works in a 16-bit manner. There is a 3V volt supply output on the chip. DMA channels number YES. 256kB is the memory size of the part. The base part number ATXMEGA256 can be used to find alternatives. The efficiency of this device can be improved when operating at a frequency of 32MHz. The device works in YES PWM channels. Located on the chip are 64 pins. The clock has 7 timers or counters on it. There are 64 pins on it. In this device, there is a AVR RISC CPU embedded within it. It programs in 50 Programmable I/O. I would like to mention a few additional features such as IT ALSO OPERATES IN 12 MHZ AT 1.6V MIN in order to name a few. 6 UART channels are available on it. A total of 16 channels of ADC are available on this device. The device uses 22 PWM channels. There are 2 I2C channels included in the part, which has been designed for the purpose.
