Description
The ATmega328PB-ANR is an enhanced 8-bit AVR microcontroller from Microchip, based on the popular ATmega328P but with additional features. It includes 32KB Flash, 2KB SRAM, and 1KB EEPROM, along with improved peripherals like two UARTs, two I²C, and two SPI interfaces.
Key upgrades over the ATmega328P include:
- Dual USART for enhanced serial communication.
- Independent PLL clock for USB and other peripherals.
- More timers (four 16-bit) and additional PWM channels.
- Better noise immunity and lower power consumption.
It operates at 1.8V–5.5V, making it suitable for battery-powered and industrial applications. The -ANR suffix indicates a TQFP-32 package, ideal for compact designs.
Common uses include Arduino-compatible boards, embedded systems, and IoT devices. Its backward compatibility with the ATmega328P allows easy migration for existing projects.
For detailed specs, refer to the Microchip datasheet.
