The Microchip ATXMEGA64A3U-MHR is a low-power AVR XMEGA microcontroller operating at up to 32 MHz. It provides 64 KB of flash memory and 4 KB of RAM. With a supply voltage range of 1.6V to 3.6V, it is optimized for battery-powered applications. The device includes DMA, brown-out detection, POR, PWM, and WDT. Packaged in a 64-VFQFN, it operates from -40°C to 85°C, making it suitable for portable and industrial designs.
- Ultra-low voltage operation: 1.6V minimum enables single-cell battery designs.
- DMA efficiency: Reduces CPU load for data streaming, improving power efficiency.
- High-speed 32 MHz core: Handles complex algorithms while maintaining low power.
- Compact 64-pin package: Balances I/O count with board space.
- Rich analog features: Multiple ADC channels with DMA support for multi-sensor acquisition.
Battery-Powered IoT Sensors
The 1.6V-3.6V range allows direct CR2032 coin cell operation. The 32 MHz core processes sensor data while DMA handles ADC sampling to save power.
Portable Audio Devices
DMA transfers audio samples to DAC without CPU intervention. The 4 KB RAM buffers audio frames for gapless playback.
Smart Home Controllers
With 64 KB flash, it stores Zigbee or proprietary RF protocol stacks. The PWM outputs drive dimmable LED lighting.
Medical Monitoring Wearables
Low-voltage operation extends battery life in heart-rate monitors. The brown-out detection ensures safe shutdown during low battery.
Data Acquisition Systems
DMA and multiple ADC channels enable simultaneous sampling of multiple sensors. The 32 MHz speed supports real-time signal processing.
Industrial Sensor Nodes
The -40°C to 85°C range suits factory floor environments. Its 64-pin package allows integration with CAN transceivers for industrial networks.
