Description
The 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 designer to optimize the device for power
consumption versus processing speed.
The 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 a 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 ATmega328PB provides the following features: 32Kbytes of In-System Programmable Flash with
Read-While-Write capabilities, 1Kbytes EEPROM, 2Kbytes SRAM, 27 general purpose I/O lines, 32
general purpose working registers, five flexible Timer/Counters with compare modes, internal and
external interrupts, two serial programmable USART, two byte-oriented 2-wire Serial Interface (I2C), two
SPI serial ports, a 8-channel 10-bit ADC in TQFP and QFN/MLF package, a programmable Watchdog
Timer with internal Oscillator, Clock failure detection mechanism and six software selectable power
saving modes. The Idle mode stops the CPU while allowing the SRAM, Timer/Counters, USART, 2-wire
Serial Interface, SPI port, and interrupt system to continue functioning. PTC with enabling up to 24 selfcap and 144 mutual-cap sensors. The Power-down mode saves the register contents but freezes the
Oscillator, disabling all other chip functions until the next interrupt or hardware reset. In Power-save
mode, the asynchronous timer continues to run, allowing the user to maintain a timer base while the rest
of the device is sleeping. Also ability to run PTC in power-save mode/wake-up on touch and Dynamic
on/off of PTC analog and digital portion. The ADC Noise Reduction mode stops the CPU and all I/O
modules except asynchronous timer, PTC, and ADC to minimize switching noise during ADC
conversions. In Standby mode, the crystal/resonator Oscillator is running while the rest of the device is
sleeping. This allows very fast start-up combined with low power consumption.
The device is manufactured using high density non-volatile memory technology. The On-chip ISP Flash
allows the program memory to be reprogrammed In-System through an SPI serial interface, by a
conventional nonvolatile memory programmer, or by an On-chip Boot program running on the AVR core.
The Boot program can use any interface to download the application program in the Application Flash
memory. Software in the Boot Flash section will continue to run while the Application Flash section is
updated, providing true Read-While-Write operation. By combining an 8-bit RISC CPU with In-System
Self-Programmable Flash on a monolithic chip, the ATmega328PB is a powerful microcontroller that
provides a highly flexible and cost effective solution to many embedded control applications.
The ATmega328PB is supported with a full suite of program and system development tools including: C
Compilers, Macro Assemblers, Program Debugger/Simulators, In-Circuit Emulators, and Evaluation kits.

Port B (PB[7:0]) XTAL1/XTAL2/TOSC1/TOSC2
Port B is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each pin). The Port B
output buffers have symmetrical drive characteristics with both high sink and source capability. As inputs,

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.
If the Internal Calibrated RC Oscillator is used as chip clock source, PB[7:6] is used as TOSC[2:1] input
for the Asynchronous Timer/Counter2 if the AS2 bit in ASSR is set.
5.1.4
Port C (PC[5:0])
Port C is a 7-bit bi-directional I/O port with internal pull-up resistors (selected for each pin). The PC[5:0]
output buffers have symmetrical drive characteristics with both high sink and source capability. As inputs,
Port C pins that are externally pulled low will source current if the pull-up resistors are activated. The Port
C pins are tri-stated during a reset condition even if the clock is not running.
5.1.5
PC6/RESET
If the RSTDISBL Fuse is programmed, PC6 is used as an I/O pin. Note that the electrical characteristics
of PC6 differ from those of the other pins of Port C.
If the RSTDISBL Fuse is unprogrammed, PC6 is used as a Reset input. A low level on this pin for longer
than the minimum pulse length will generate a Reset, even if the clock is not running. Shorter pulses are
not guaranteed to generate a Reset.
The various special features of Port C are elaborated in the Alternate Functions of Port C section.
5.1.6
Port D (PD[7:0])
Port D is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each pin). The Port D
output buffers have symmetrical drive characteristics with both high sink and source capability. As inputs,
Port D pins that are externally pulled low will source current if the pull-up resistors are activated. The Port
D pins are tri-stated during a reset condition even if the clock is not running.
5.1.7
Port E (PE[3:0])
Port E is an 4-bit bi-directional I/O port with internal pull-up resistors (selected for each pin). The Port E
output buffers have symmetrical drive characteristics with both high sink and source capability. As inputs,
Port E pins that are externally pulled low will source current if the pull-up resistors are activated. The Port
E pins are tri-stated during a reset condition even if the clock is not running.
5.1.8
AVCC
AVCC is the supply voltage pin for the A/D Converter, PC[3:0], and PE[3:2]. It should be externally
connected to VCC, even if the ADC is not used. If the ADC is used, it should be connected to VCC through
a low-pass filter. Note that PC[6:4] use digital supply voltage, VCC.
5.1.9
AREF
AREF is the analog reference pin for the A/D Converter.
5.1.10
ADC[7:6] (TQFP and VFQFN Package Only)
In the TQFP and VFQFN package, ADC[7:6] serve as analog inputs to the A/D converter. These pins are
powered from the analog supply and serve as 10-bit ADC channels.

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.
For I/O Registers located in extended I/O map, “IN”, “OUT”, “SBIS”, “SBIC”, “CBI”, and “SBI” instructions
must be replaced with instructions that allow access to extended I/O. Typically “LDS” and “STS”
combined with “SBRS”, “SBRC”, “SBR”, and “CBR”.
