ATXMEGA8E5-AU

Overview

The ATXMEGA8E5-AU is an 8/16-bit microcontroller based on the AVR enhanced RISC architecture, operating at a maximum frequency of 32MHz. It features 8KB of in-system self-programmable flash with a 2KB boot section, 512 bytes of EEPROM, and 1KB of internal SRAM. The device operates within a voltage range of 1.6V to 3.6V and supports frequencies up to 12MHz at 1.6V and 32MHz at 2.7V. It includes a four-channel enhanced DMA controller, an eight-channel event system, three 16-bit timer/counters, two USARTs, one SPI, one TWI, a sixteen-channel 12-bit ADC, and a two-channel 12-bit DAC.
