概述

Description

ATxmega8E5-MU is an 8-bit AVR XMEGA microcontroller from Microchip/Atmel, part of the XMEGA-E5 family. It comes in a compact 32-pin MU package and uses the XMEGA core with a rich peripheral set. Peripherals typically include multiple serial interfaces (USART, SPI, I2C), analog peripherals (ADC and DAC), timers/PWM, and a DMA/Event System for peripheral-to-peripheral data routing. It supports low-power modes for battery-powered designs and is aimed at compact control, sensing, and embedded applications. Development is via Microchip Studio/Atmel Studio with GCC toolchains. For exact memory sizes (Flash/RAM), I/O count, and power specs, consult the official datasheet and product page.

Features

Key features of ATXMEGA8E5-MU (XMEGA E5 family):
