The ATXMEGA32C4-CUR is a high-performance AVR XMEGA microcontroller in a 49-ball VFBGA. It features 32KB flash and 4KB RAM, running at 32MHz from 1.6V to 3.6V. Integrated PWM, POR, BOD, and WDT make it ideal for advanced low-power embedded applications.

  • Large 32KB flash – supports complex firmware and data logging.
  • 4KB SRAM – enables larger buffers and richer data processing.
  • Low 1.6V operation – extends battery life significantly.
  • Compact VFBGA – ideal for space-constrained PCBs.
  • 32MHz AVR core – balances speed and power efficiency.

Advanced Sensor Hubs

With 32KB flash and 4KB RAM, it can aggregate multiple sensor inputs in smart building systems.

Motor Control Drones

PWM outputs and 32MHz speed enable precise ESC control for small quadcopters.

Portable Audio Devices

The low voltage and ample memory support audio processing in compact players.

Industrial Data Loggers

Robust reset features and 4KB RAM buffer data reliably in harsh environments.

Smart Agriculture Nodes

Battery-friendly 1.6V operation suits soil moisture and climate monitoring in fields.

Medical Implantable Devices

The tiny BGA package and low power are suitable for miniaturized implants.
