The ATXMEGA192A3U-MHR from Microchip is a low-power AVR XMEGA microcontroller in a 64-VFQFN package. It operates at 32MHz with 192KB flash and 16K RAM. With a supply range of 1.6V to 3.6V, it integrates brown-out reset, DMA, POR, PWM, and WDT for energy-efficient embedded applications.
- Ultra-low voltage (1.6V) enables single-cell battery operation.
- DMA offloads data movement, reducing power consumption.
- 192KB flash supports complex application code.
- Compact VFQFN package saves board space.
Battery-Powered IoT Sensors
1.6V operation extends battery life; DMA transfers sensor data with minimal CPU wake time.
Portable Medical Devices
Low voltage and 32MHz speed enable real-time ECG filtering; 192KB flash stores patient logs.
Smart Home Controllers
PWM drives LED dimmers; brown-out reset ensures reliable state recovery.
Data Loggers
16K RAM buffers samples; DMA writes to external SPI flash without CPU overhead.
Wearable Fitness Trackers
VFQFN package is compact; 1.6V rail allows direct coin-cell operation.
Industrial Sensor Nodes
WDT and POR provide robustness in remote installations; 85°C rating covers most enclosures.
