Overview
The Atmel AVR XMEGA is a family of low power, high performance, and peripheral rich 8/16-bit microcontrollers based
on the AVR enhanced RISC architecture. By executing instructions in a single clock cycle, the AVR XMEGA devices
achieve CPU throughput approaching one million instructions per second (MIPS) per megahertz, allowing the system
designer to optimize power consumption versus processing speed.
The AVR CPU combines a rich instruction set with 32 general purpose working registers. All 32 registers are directly
connected to the arithmetic logic unit (ALU), allowing two independent registers to be accessed in a single instruction,
executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs many times
faster than conventional single-accumulator or CISC based microcontrollers.
The XMEGA C3 devices provide the following features: in-system programmable flash with read-while-write capabilities;
internal EEPROM and SRAM; four-channel event system and programmable multilevel interrupt controller, 50 general
purpose I/O lines, 16-bit real-time counter (RTC); five, 16-bit timer/counters with compare and PWM channels; three
USARTs; two two-wire serial interfaces (TWIs); one full speed USB 2.0 interface; two serial peripheral interfaces (SPIs);
one sixteen-channel, 12-bit ADC with programmable gain; two analog comparators (ACs) with window mode;
programmable watchdog timer with separate internal oscillator; accurate internal oscillators with PLL and prescaler; and
programmable brown-out detection.
The program and debug interface (PDI), a fast, two-pin interface for programming and debugging, is available.
The XMEGA C3 devices have five software selectable power saving modes. The idle mode stops the CPU while allowing
the SRAM, event system, interrupt controller, and all peripherals to continue functioning. The power-down mode saves
the SRAM and register contents, but stops the oscillators, disabling all other functions until the next TWI, USB resume, or
pin-change interrupt, or reset. In power-save mode, the asynchronous real-time counter continues to run, allowing the
application to maintain a timer base while the rest of the device is sleeping. In standby mode, the external crystal
oscillator keeps running while the rest of the device is sleeping. This allows very fast startup from the external crystal,
combined with low power consumption. In extended standby mode, both the main oscillator and the asynchronous timer
continue to run. To further reduce power consumption, the peripheral clock to each individual peripheral can optionally be
stopped in active mode and idle sleep mode.
Atmel offers a free QTouch library for embedding capacitive touch buttons, sliders and wheels functionality into AVR
microcontrollers.
The devices are manufactured using Atmel high-density, nonvolatile memory technology. The program flash memory can
be reprogrammed in-system through the PDI. A boot loader running in the device can use any interface to download the
application program to the flash memory. The boot loader software in the boot flash section will continue to run while the
application flash section is updated, providing true read-while-write operation. By combining an 8/16-bit RISC CPU with
in-system, self-programmable flash, the AVR XMEGA is a powerful microcontroller family that provides a highly flexible
and cost effective solution for many embedded applications.
All Atmel AVR XMEGA devices are supported with a full suite of program and system development tools, including: C
compilers, macro assemblers, program debugger/simulators, programmers, and evaluation kits.
