ATMEGA48PB-MNR

The ATmega48PB 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 ATmega48PB achieves throughputs approaching 1MIPS/MHz, allowing the system designer to optimize power consumption versus processing speed.
