ATXMEGA128B3-AU Product Details

ATXMEGA128B3-AU Overview


The package has a 64-TQFP shape. With 36 I/Os, it's pretty good. The Microcontroller's mounting type is Surface Mount and this IC chip has the following features. As the name implies, this Microcontroller is based on the 8/16-Bit core. As far as its program memory type is concerned, it is FLASH. Temperatures within -40°C~85°C TA range are measured by this Microcontroller. The AVR® XMEGA® B3 series is comprised of this electrical component. The electronic part has a program memory size of 128KB 128K x 8. There's a AVR Core Processor inside. The IC chip fits into the MICROCONTROLLER, RISC uPs/uCs/Peripheral ICs category. There are 64 terminations on the IC chip. 16-bits are the size of the data that comes with MCU. A 3V volt supply is provided by the Microcontroller chip. In addition to that, MCU chip has YES DMA channels. Its memory size is 128kB. It is possible to find alternatives to the base part number ATXMEGA128 by using the part number search tool. An effective performance can be achieved at a frequency of 32MHz. It is possible to access the 64 pins on the chip. A total of 6 PWM channels are being used by the device.
