The ATMEGA32A is a high-performance 8-bit AVR MCU with 32KB flash and 2KB SRAM. It runs at 16MHz from 2.7V to 5.5V, integrating brown-out reset, POR, PWM, and WDT. The 44-VFQFN package is ideal for space-constrained industrial and automotive boards.
- Wide 2.7-5.5V range – simplifies dual-voltage system design.
- 16MHz AVR core – efficient for mid-range control loops.
- Integrated WDT and brown-out – enhances field reliability.
- Compact VFQFN – reduces PCB area in dense layouts.
Automotive Sensor Interfaces
2.7V min voltage supports 3.3V CAN transceivers; 16MHz handles LIN protocol.
Industrial Process Controllers
PWM and WDT ensure reliable timing for valve actuation and fault monitoring.
Consumer Appliances
