ATmega328PB AVR Atmel QFN-32

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 1MIPS per MHz. This empowers system designers to optimize the device for power consumption versus processing speed.

ATmega328PB is not a drop-in replacement for ATmega328 variants, but a new device. However, the functions are backward compatible with the existing ATmega328 functions. Existing code for these devices will work in the new devices without changing existing configuration or enabling new functions. The code that is available for your existing ATmega328 variants will continue to work on the new ATmega328PB device.

The ATmega328PB is the first 8-bit Atmel AVR® device to feature the successful Atmel QTouch® Peripheral Touch Controller (PTC).
