概要

Description

ATxmega32A4U-AUR is a Microchip/Atmel AVR XMEGA microcontroller. It uses the 8/16‑bit AVR XMEGA core and packs a rich set of peripherals on a single chip.
Key features (typical for this device):
- USB full‑speed device controller
- Multiple serial interfaces (USART/UART, SPI, TWI/I2C)
- 12‑bit ADC (with optional DAC)
- Timers, PWM/capture modules, and a flexible DMA/event system
- On‑chip flash, RAM, and EEPROM memory
- Low‑power modes and wide operating voltage/clock ranges
- Packaging variants indicated by the AUR suffix (AU package, RoHS, etc.)
Common uses:
- USB peripherals, data acquisition, sensing, embedded control, and motor/embedded instrumentation
Note:
Exact memory sizes, pin count, clock limits, and package details vary by variant. Refer to the latest datasheet/product page for precise specs and the AUR package characteristics.

Features
