8/16-Bit AVR XMEGA Microcontrollers
Atmel AVR XMEGA microcontrollers deliver the best possible combination of real-time performance, high integration and low power consumption for 8/16-bit MCU applications.
Atmel AVR XMEGA devices employ advanced analogue-to-digital converters (ADCs) that deliver both high speed and high resolution. These ADCs offer up to four conversion channels with different result registers, which can have different setup and configuration processes. This provides easier use since different software modules can access and use an ADC independently.
The Event System facilitates inter-peripheral signaling for short and 100% predictable response time. This ensures real-time control, and also offloads the CPU because each time an event is used, one interrupt with context switch is eliminated. Most of the peripherals and the DMA controller are connected to the Event System. The AVR XMEGA E series features an asynchronous peripheral Event System instead.
The AVR XMEGA 4-channel direct memory access (DMA) controller can be used for fast, CPU-independent data transfer between any combination of data memory and peripherals.
AVR XMEGA devices use the Atmel AVR CPU. The instruction set and design of the CPU are tuned to minimize code size and maximize execution speed. Its true single-cycle execution of arithmetic and logic operations means AVR XMEGA microcontrollers perform close to 1MIPS per MHz. The fast-access register file with 32 x 8-bit general-purpose working registers is directly connected to the arithmetic logic unit (ALU). During a single clock cycle, the ALU can be fed two arbitrary registers, do a requested operation, and write back the result. It provides efficient support for 8-, 16- and 32-bit arithmetic.
