Product Overview

The ATXMEGA128A1-AU is a 8-bit low power High Performance Microcontroller 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 Atmel 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 program and debug interface (PDI), a fast, two-pin interface for programming and debugging is available.
  • Non-volatile program and data memories
  • Four-channel DMA controller
  • Eight-channel event system
  • Eight USARTs with IrDA support for one USART
  • Four two-wire interfaces with dual address match (I²C and SMBus compatible)
  • Four serial peripheral interfaces (SPIs)
  • AES and DES crypto engine
  • 16-bit Real time counter (RTC) with separate oscillator
  • Four analog comparators (ACs) with window compare function and current sources
  • Programmable watchdog timer with separate on-chip ultra low power oscillator
  • QTouch® library support capacitive touch buttons, sliders and wheels
  • Power-on reset and programmable brown-out detection
  • Internal and external clock options with PLL and prescaler
  • Programmable multilevel interrupt controller
  • Five sleep modes
