The Microchip ATMEGA328PB-MU is an 8-bit AVR microcontroller in a 32-VFQFN package with exposed pad for thermal management. It operates from 1.8V to 5.5V and runs at up to 20MHz, providing 32KB Flash and 2KB RAM. This enhanced version of the classic ATmega328P adds more peripherals, including additional timers and communication interfaces, while maintaining code compatibility. It is ideal for applications requiring a balance of performance, memory, and low power.
- Enhanced ATmega328P: Offers more peripherals while staying code-compatible with the popular original.
- Wide voltage range (1.8V-5.5V): Flexible for battery or 5V logic systems.
- 32KB Flash: Ample space for complex firmware.
- 20MHz speed: Fast enough for real-time control applications.
- Exposed pad package: Improves heat dissipation for reliable operation.
3D Printer Controllers
The 32KB Flash and 20MHz speed handle G-code interpretation and stepper motor control, with PWM outputs driving motor drivers and heater elements.
Arduino-Compatible Projects
As an enhanced version of the popular ATmega328P, it is drop-in compatible with many Arduino shields, offering additional peripherals for advanced makers.
Industrial Data Loggers
