3. Overview
The ATmega48PB/88PB/168PB 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/88PB/168PB achieves
throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus
processing speed.

The AVR core combines a rich instruction set with 32 general purpose working registers. All the 32 registers are
directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in one
single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving
throughputs up to ten times faster than conventional CISC microcontrollers.
The ATmega48PB/88PB/168PB provides the following features: 4/8/16Kbytes of In-System Programmable Flash
with Read-While-Write capabilities, 256/512/512 bytes EEPROM, 512/1K/1Kbytes SRAM, 27 general purpose I/O
lines, 32 general purpose working registers, three flexible Timer/Counters with compare modes, internal and
