ATMEGA88PB-AU 8-bit ATMega AVR® microcontroller, 8 kB, 20 MHz, TQFP-32

The ATmega48PB/88PB/168PB is a low-power CMOS 8-bit microcontroller based on the AVR® enhanced RISC architecture. By executing powerful commands in a single clock cycle, the ATmega48PB/88PB/ 168PB achieves throughputs of nearly 1 MIPS per MHz, allowing system designers to optimise power consumption against processing speed.
