Generally known excellent properties of 8 bit RISC processors AVR Atmega, were further improved by developers in Atmel Corporation in this new line of 8/16 bit AVR XMEGA processors. That they succeeded, testifies this concise overview of innovations:
- fast precise 12 bit AD converter (ADC)
- fast 12 bit DA converter (DAC)
- DMA controller for CPU independent data transfer
- event system, most of peripherials and the DMA controller can use it, what significantly offloads CPU
- ultra low power consumption - picoPOWER technology for a minimal consumption of 100nA in the Power down mode
- EBI bus for RAM extension, peripherials (LCD) or memory-mapped devices
- free Qtouch library for operation with capacitive touch panels
- full speed USB connectivity without external crystal (at some models)
- free AVR Software Framework including all common USB device classes
- LCD display driver for a direct connection of LCD to processor
- true 1.6V operation and speeds up to 32 MHz
- AES, DES crypting protocols
- 3-level interrupt controller (priority is freely user definable)
- CRC modul (cyclic redundancy check) for data integrity check
- RTC (real time clock) with optional battery backup system
- analog comparators with adjustable hysteresis and propagation delay
- external oscillator failure detection – in case of failure, CPU will start operation with the internal 2MHz oscillator
- supply voltage 1.6 to 3.6V
You can watch the features overview of XMEGA processors in the video under this article. Basic informations will provide you the XMEGA Features overview as well as the Getting started document.
