Product Overview

The ATXMEGA128A1-CU is a low power, high-performance 16-bit Microcontroller based on the AVR enhanced RISC architecture. By executing instructions in a single clock cycle, the AVR XMEGA devices achieve CPU throughput approaching 1MIPS per MHz 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 AVR XMEGA A1 device provides 128kB self-programming flash program memory, 8kB boot code section, 8kB SRAM, 2048byte EEPROM and up to 32MIPS throughput at 32MHz.
  • Power-on reset and programmable brown-out detection
  • Internal and external clock options with PLL and prescaler
  • Programmable multilevel interrupt controller
  • Sleep modes - Idle, power-down, standby, power-save, extended standby
  • Programming and debug interfaces - JTAG (IEEE 1149.1 com) interface, including boundary scan, PDI
  • 4-channel DMA Controller
  • 8-channel Event system
  • Eight 16-bit timers/counters
  • Eight USARTs with IrDA support for one USART
  • Four 2-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
  • Two 16-channel, 12-bit, 2MSPS analog-to-digital converters
  • Two 2-channel, 12-bit, 1MSPS digital to analog converters
  • Four analog comparators (ACs) with window compare function and current sources
  • External interrupts on all general purpose I/O pins
  • Programmable watchdog timer with separate on-chip ultra low power oscillator
  • QTouch® library support
