Microchip AVR, XMEGA A4U Microcontroller, 32 MHz, 32kB FLASH, 44-Pin TQFP

The Microchip 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.

• Four-channel DMA controller
• Eight-channel event system
• Five 16-bit timer/counters
• Three timer/counters with 4 output compare or input capture channels
• Two timer/counters with 2 output compare or input capture channels
• High-resolution extensions on all timer/counters
• Advanced waveform extension (AWeX) on one timer/counter
