The Microchip ATXMEGA128A1U-AN is an extended-temperature AVR microcontroller with 128KB flash and 8KB SRAM. Operating from 1.6V to 3.6V at 32MHz, it features DMA and PWM in a 100-TQFP package. Designed for harsh environments requiring -40°C to 105°C operation.
- Extended temperature range: -40°C to 105°C for automotive and industrial use.
- Low voltage operation: 1.6V minimum reduces power consumption.
- High integration: DMA and PWM reduce external components.
- Proven AVR core: Reliable and easy-to-program architecture.
Automotive Engine Control
The 105°C rating allows operation under hood where ambient temperatures are extreme.
Oil and Gas Drilling Equipment
High-temperature tolerance and DMA support reliable data acquisition in downhole tools.
Industrial Furnace Controllers
With 32MHz and PWM, it can manage precise temperature profiles in high-heat environments.
Avionics Sensors
Extended temperature range and low power make it suitable for cabin pressure and temperature monitoring.
Outdoor Telemetry Units
Robust operation from -40°C to 105°C ensures performance in desert or arctic installations.
Power Grid Monitors
DMA and ADC capabilities enable continuous voltage/current monitoring in substations.
