Hardware communication interfaces: USART, SPI, TWI (I2C) ATMEGA328P-AUATMEGA328P-AU TQFP - Product OverviewThe high-performance Atmel picoPower 8-bit AVR RISC-based microcontroller combines 32KB ISP flash memory.6 channels of 10-bit analog-to-digital converter.Specification of the ATmega328P microcontroller Our offer has also version Atmega328P with installed Arduino bootlader. In order to maintain full functionality of the Arduino, you need to upload the bootloader available on the official website with the help of AVR programmer. The subject of the sale is the ATmega328P microcontroller, Arduino Uno can be purchased separately. In case of damage of the microcontroller, the user can replace it. The Atmega328P chip in a removable, through hole case, has been used in popular modules Arduino Uno. It was used in the popular Arduino Uno module. Microcontroller from AVR family from Atmel in the through hole case (DIP). Product description: AVR microcontroller - ATmega328P-U DIP iNode - sensors and modules Bluetooth Android. ![]() Components for 3D printers construction.By default the fuses of the ATmega328p are configured that the internal 8MHz. Laser cutting machines - engravers, plotters The ATmega328p has two internal oscillators, one clocked at 8MHz and one at 128kHz.A low level on this pin for longer than the minimum pulse length will generate a reset, even if the clock is not running. This blog mainly introduces its pinout, datasheet, applications and other detailed information of ATMEGA328P. If the RSTDISBL fuse is not used, PC6 is used as a reset input. 32KB 16K x 16 FLASH AVR 8-Bit Microcontroller AVR® ATmega Series ATMEGA328P 28 Pin 20MHz 5V 28-DIP (0.300, 7.62mm) ATMEGA328P is a high performance, low power controller from Microchip. If the RSTDISBL fuse is programmed, PC6 is used as an input pin. The port C pins are tri-stated when a reset condition becomes active, even if the clock is not running. As inputs, Port C pins that are externally pulled low will source current if the pull-up resistors are activate. Symmetrical drive characteristics with both high sink and source capability. Port C is a 7-bit bi-directional I/O port with internal pull-up resistors ( for each bit). If the internal calibrate RC oscillator is use as chip clock source, PB7.6 is use as TOSC2.1 input for the asynchronous Timer/Counter2 if the AS2 bit in ASSR is set. The Port B pins are tri-stated when a reset condition becomes active, even if the clock is not running.ĭepending on the clock selection fuse settings, PB6 can be use as input to the inverting oscillator amplifier and input to the internal clock operating circuit.ĭepending on the clock selection fuse settings, PB7 can be use to output from the inverting oscillator amplifier. The Port B output buffers have symmetrical drive characteristics with both high sink and source capability.Īs inputs, port B pins that are externally pull low will source current if the pull-up resistors are activated. Port B is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). Six sleep modes: Idle, ADC noise reduction, power-save, power-down, standby, and extended standbyġ.External and internal interrupt sources.Power-on reset and programmable brown-out detection.Programmable watchdog timer with separate on-chip oscillator.Byte-oriented 2-wire serial interface (Phillips I2 C compatible).8-channel 10-bit ADC in TQFP and QFN/MLF package.Real time counter with separate oscillator.One 16-bit Timer/Counter with separate pre-scalier, compare mode, and capture mode.Two 8-bit Timer/Counters with separate pre-scalier and compare mode.True read-while-write operation Peripheral features In-system programming by on-chip boot program Optional boot code section with independent lock bits.32K bytes of in-system self-programmable flash program memory.High endurance non-volatile memory segments 32 x8 general purpose working registers.131 powerful instructions – most single clock cycle execution. ![]() Features: High performance, low power AVR® 8-bit microcontroller Advanced RISC architecture In addition, the ATmega328P use I/O space from 0圆0 – 0xFF in SRAM where only the ST/STS/STD and LD/LDS/LDD instructions can be use. The I/O memory can be access directly, or the data space locations following those of the register file, 0x20 – 0x5F. The I/O memory space contains 64 addresses for CPU peripheral functions as control registers, SPI, and other I/O functions.
