It is this 28-pin semiconductor chip of Fig-1.1. The full name is “Micro Controlling Unit”, the short name is “Microcontroller”, and the abbreviated name is “MCU”. The MCU can process only 8-bit data at a time. (a) Pictorial view of ATmega328P MCU (b) Pin/signal diagram of ATmega328P MCU Figure-1.1: Pictorial view, pin diagram, and pin ...Thu, 23 Apr 2026 20:01:00 GMThttps://forum.arduino.cc/t/block-diagram-for-the-internal-resources-of-atmega328p-mcu/1391697(1) M10 (Module-10): The ATmega328P MCU of the Arduino UNO Board runs at 16 MHz clock frequency. If desired, it can be operated by an 8 MHz internal oscillator (M11). Using internal Clock Prescaler Divider (not shown in Fig-1), the MCU can be run at 31250 Hz to 16 MHz.Mon, 13 Apr 2026 02:41:00 GMThttps://forum.arduino.cc/t/using-arduino-ide-for-standalone-atmega328p-board/1274532I am exploring buying ATMega328P chips and using them natively on a PCB. I have an ASIX Presto programmer is able to load the hex file built in the Arduino IDE. I am considering running the board using the internal 8 mHZ clock and have a question about changes needed to accommodate that. I see that in the boards.txt file the fuse bits are defined, as is the clock speed. Should I be editing uno ...Tue, 21 Apr 2026 00:58:00 GMThttps://forum.arduino.cc/t/extend-atmega328p-au-pins/1111491Hi Guys, I'm looking a way extend the pin's ATMEGA328P-AU chip without using any other component like shift register (this will be my last solution). My project will use the 23 IO pins available (in green) and i need at least 3 extra IO pins, So I have ADC7, AREF, ADC6, AVCC. Questions: ADC7 and ADC6: I know we can use analog pin as output pin, so OK. AREF: I read better to stay away from it ...Thu, 23 Apr 2026 09:17:00 GMThttps://forum.arduino.cc/t/atmega328-vs-atmega328p-what-are-the-differences/59850title says it all, what are the differences? i am thinking there would be an issue burning a bootloader to the 328 since it is probably expecting the 328p, and is the 328 newer or older than the 328p? everything i have has a 328p in it but the 328 is $1 cheaper and that adds up quick in volume, so please let me know the difference. bobSat, 25 Apr 2026 09:36:00 GMThttps://forum.arduino.cc/t/atmega328p-esp8266-wifi-tutorial/944380Hi, So I had quite some trouble getting my board to work as most things are not straightforward. Therefore, I am writing this short tutorial with everything I learned so people do not have to rediscover everything on their own. This guide is specifically for the UNO R3 + ATmeg328p + ESP8266 WIFI (4Mb) USB - TTL. This thing still feels like a black box to me, so if you have any more insight ...Fri, 24 Apr 2026 00:55:00 GMThttps://forum.arduino.cc/t/what-are-the-differences-of-atmega328-atmega328p-and-atmega-328pb/1153356The difference between the 328 and 328P is "picopower", which might mean lower power consumption in powerdown modes, but the only visible difference is the ability to turn off brown-out detection in software. The 328PB should have been a different part number . It has extra I2C, SPI, and UART peripherals, two additional 16bit timers, the ability to use what were analog-only pins for digital IO ...Thu, 23 Apr 2026 20:08:00 GMThttps://forum.arduino.cc/t/atmega328p-eeprom-corruption-despite-bod-enabled/1386124Hi everyone, I'm working on a custom board based on the ATmega328P-AU, driving two stepper motors via TMC2660 drivers, and I'm running into a frustrating EEPROM corruption issue. 💡 The Setup: MCU: ATmega328P-AU, running at 5V Motor Drivers: 2x TMC2660 (SPI + STEP/DIR) Power Supply: 5V rail shared between MCU and TMC drivers EEPROM: Used to store a single integer (saved_insrt_len) only once ...Fri, 10 Apr 2026 08:57:00 GMThttps://forum.arduino.cc/t/is-atmega328p-outdated/1126276Thanks to Arduino, my journey in electronics has evolved from using Uno and Nano development boards to creating my own standalone PCBs using C++. Over the years, I have dedicated myself to perfecting my projects and gaining expertise in working with chips like the ATmega328P and programming in C++. However, a concern that arises is the inevitable obsolescence of certain chips just as I ...Wed, 22 Apr 2026 20:17:00 GMThttps://forum.arduino.cc/t/atmega328p-cant-upload-code/1374383Topic Replies Views Activity Atmega328p programieren Deutsch 12 205 April 24, 2025 External ZIF board and connecting to upload Arduino bootloader onto raw ATMEGA 328p chip 3rd Party Boards 8 59 December 19, 2025 Can't upload sketch to ATMEGA328PB board Uploading 18 235 November 16, 2025 Burning bootloader on ATMEGA328P-AN using Arduino Uno ...Thu, 16 Apr 2026 14:33:00 GMT
