XMEGA D4

3. 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 reg-

isters 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 conven-

tional single-accumulator or CISC based microcontrollers.

The AVR XMEGA D4 devices provide the following features: in-system programmable flash with

read-while-write capabilities; internal EEPROM and SRAM; four-channel event system and pro-

grammable multilevel interrupt controller; 34 general purpose I/O lines; 16-bit real-time counter

(RTC); four flexible, 16-bit timer/counters with compare and PWM channels; two USARTs; two

two-wire serial interfaces (TWIs); two serial peripheral interfaces (SPIs); one twelve-channel, 12-

bit ADC with programmable gain; two analog comparators (ACs) with window mode; program-

mable 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 debug-

ging, is available.

The XMEGA D4 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, or pin-change interrupt, or reset.

In power-save mode, the asynchronous real-time counter continues to run, allowing the applica-

tion 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 develop-

ment tools, including: C compilers, macro assemblers, program debugger/simulators,

programmers, and evaluation kits.
