Description
The ATmega328PB-MUR is an enhanced 8-bit AVR microcontroller from Microchip, based on the popular ATmega328P but with additional features. It comes in a QFN-32 package (MLF-32) and is designed for surface-mount applications.
### Key Features:
- Enhanced Peripherals: Includes two UARTs, two I²C, and two SPI interfaces (vs. one each in the ATmega328P).
- Clock Speed: Up to 20 MHz with 32KB Flash, 2KB SRAM, and 1KB EEPROM.
- Low Power: Supports multiple sleep modes for energy efficiency.
- Wide Voltage Range: Operates at 1.8V–5.5V, making it suitable for battery-powered devices.
- PWM & ADC: 6 PWM channels and an 8-channel 10-bit ADC.
### Applications:
Ideal for embedded systems, IoT devices, DIY projects (like Arduino-compatible boards), and industrial control systems.
The -MUR suffix indicates a tape-and-reel packaging for automated assembly. Its extended peripheral set makes it a versatile upgrade over the standard ATmega328P.
