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 AVR XMEGA E5 devices provide the following features: in-system programmable flash with read-while-write

capabilities; internal EEPROM and SRAM; four-channel enhanced DMA (EDMA) controller; eight-channel event system

with asynchronous event support; programmable multilevel interrupt controller; 26 general purpose I/O lines; CRC-16

(CRC-CCITT) and CRC-32 (IEEE 802.3) generators; one XMEGA Custom Logic module with timer, counter and logic

functions (XCL); 16-bit real-time counter (RTC) with digital correction; three flexible, 16-bit timer/counters with compare

and PWM channels; two USARTs; one two-wire serial interface (TWI) allowing simultaneous master and slave; one

serial peripheral interface (SPI); one sixteen-channel, 12-bit ADC with programmable gain, offset and gain correction,

averaging, over-sampling and decimation; one 2-channel 12-bit DAC; two analog comparators (ACs) with window mode

and current sources; 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 AVR XMEGA E5 devices have five software selectable power saving modes. The idle mode stops the CPU while

allowing the SRAM, EDMA controller, 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, 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. In each power save, standby or extended standby mode, the low power mode of the

internal 8MHz oscillator allows very fast startup time combined with very low power consumption.

To further reduce power consumption, the peripheral clock to each individual peripheral can optionally be stopped in

active mode and idle sleep mode and low power mode of the internal 8MHz oscillator can be enabled.

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 can

continue to run. 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.
