ATmega328PB
AVRВ® Microcontroller with Core Independent Peripherals
and PicoPowerВ® Technology
Introduction
В® В® 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. Features
High Performance, Low-Power AVRВ® 8-bit Microcontroller Family Advanced RISC Architecture
– 131 Powerful Instructions
– Most Single Clock Cycle Execution
– 32 x 8 General Purpose Working Registers
– Fully Static Operation
– Up to 20 MIPS Throughput at 20 MHz
– On-Chip 2-Cycle Multiplier High Endurance Nonvolatile Memory Segments
– 32 KB of In-System Self-Programmable Flash program memory
– 1 KB EEPROM
