ATXMEGA128A1U-AU.pdf

Introduction The AVR® XMEGA® AU is a family of low power, high performance, and peripheral rich 8/16-bit microcontrollers based on the AVR enhanced RISC architecture. The XMEGA A1U is a 100-pins device ranging from 64KB to 128KB Flash, with 4KB to 8KB SRAM, 2KB EEPROM and up to 8KB boot section. The ATxmegaA1U devices operate at a maximum frequency of 32MHz. By executing instructions in a single clock cycle, the devices achieve CPU throughput approaching one million instructions per second (MIPS) per megahertz, allowing the system designer to optimize power consumption versus processing speed.
