3. Overview
8134I–AVR–12/10
The Atmel
CMOS 8/16-bit microcontrollers based on the AVR
powerful instructions in a single clock cycle, the XMEGA D3 achieves throughputs approaching
1 Million Instructions Per Second (MIPS) per MHz 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 the
32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent
registers to be accessed in one 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 XMEGA D3 devices provide the following features: In-System Programmable Flash with
Read-While-Write capabilities, Internal EEPROM and SRAM, four-channel Event System, Pro-
grammable Multi-level Interrupt Controller, 50 general purpose I/O lines, 16-bit Real Time
Counter (RTC), five flexible 16-bit Timer/Counters with compare modes and PWM, three
USARTs, two Two-Wire Interface (TWIs), two Serial Peripheral Interfaces (SPIs), one 16-chan-
nel 12-bit ADC with optional differential input with programmable gain, two analog comparators
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 2-pin interface for programming and debugging,
is available.
The XMEGA D3 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 appli-
cation to maintain a timer base while the rest of the device is sleeping. In Standby mode, the
Crystal/Resonator Oscillator is kept running while the rest of the device is sleeping. This allows
very fast start-up from 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 for each individual peripheral can optionally be
stopped in Active mode and Idle sleep mode.
The device is manufactured using Atmel's high-density nonvolatile memory technology. The pro-
gram Flash memory can be reprogrammed in-system through the PDI. A Bootloader running in
the device can use any interface to download the application program to the Flash memory. The
Bootloader 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 Atmel XMEGA D3 is a powerful microcon-
troller family that provides a highly flexible and cost effective solution for many embedded
applications.
The XMEGA D3 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.
