AVR series Microcontroller IC 8-Bit 20MHz 32KB (16K x 16) FLASH 32-TQFP (7x7) The ATMEGA328PB-AU is a low-power, high-performance 8-bit AVR microcontroller from Microchip Technology. It is an enhanced version of the widely used ATmega328P, offering additional peripherals while maintaining compatibility. It operates on the AVR RISC architecture, enabling efficient instruction execution with most instructions completed in a single clock cycle. This makes it suitable for embedded systems, industrial control, consumer electronics, and IoT applications. The device comes in a 32-pin TQFP package (AU) and integrates memory, analog features, communication interfaces, and timers into a compact solution.
