1-20PCS ATMEGA328PB-AU TQFP-32 ATMEGA328PB ATMEGA328 328PB 20MHz 32KB Flash low-power CMOS 8 Bit AVR Microcontroller chip

Introduction
The picoPower® ATmega328PB is a low-power CMOS 8-bit microcontroller based on the AVR® enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega328PB achieves throughputs close to 1 MIPS per MHz. This empowers system designers to optimize the device for power consumption versus processing speed.
