Description
ATXMEGA8E5-MU is Microchip/Atmel’s AVR XMEGA E family 8‑bit microcontroller. It uses an AVR RISC core and is offered in a 32‑pin MU (QFN) package, designed for compact, low‑power embedded control. It typically runs up to ~32 MHz and provides on‑chip flash, RAM, and EEPROM sized for small to mid‑range tasks.
Peripherals commonly include: multiple USART/UARTs, SPI, I2C, several timers (including 16/32‑bit options), PWM channels, an ADC (and analog comparator), and CRC support.
Key features include the Event System for peripheral‑to‑peripheral signaling without CPU involvement and a Peripheral DMA/data‑move capability to reduce CPU load, plus sleep modes, watchdog, and brown‑out detection for power management. Debug and programming are supported via Microchip Studio; programming interfaces typically include SPI (and related debug interfaces).
Typical applications: data logging, sensor interfacing, motor control, and other compact embedded systems. For exact memory sizes, pinout, timing, and electrical specs, consult the datasheet/product page.
