ATmega328PB Summary Datasheet

Introduction

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 Port B pins that are externally pulled low will source current if the pull-up resistors are activated. The Port B pins are tri-stated during a reset condition even if the clock is not running. Depending on the clock selection fuse settings, PB6 can be used as input to the inverting Oscillator amplifier and input to the internal clock operating circuit. Depending on the clock selection fuse settings, PB7 can be used as output from the inverting Oscillator amplifier.

ATmega328PB 6. I/O Multiplexing Each pin is by default controlled by the PORT as a general purpose I/O and alternatively it can be assigned to one of the peripheral functions. The following table describes the peripheral signals multiplexed to the PORT I/O pins. Table 6-1.

ATmega328PB 8. About Code Examples This documentation contains simple code examples that briefly show how to use various parts of the device. These code examples assume that the part specific header file is included before compilation. Be aware that not all C compiler vendors include bit definitions in the header files and interrupt handling in C is compiler dependent. Confirm with the C compiler documentation for more details.
