Atmel's ATMega328P 8-Bit Processor in 28 pin DIP package. It comes with 32K of program space. 23 I/O lines, 6 of which are channels for the 10-bit ADC. Runs up to 20MHz with external crystal. Package can be programmed in circuit. 1.8V to 5V operating voltage! The famous Arduino Deumilanove, and Arduino UNO is using this ATMega microcontroller. Anyhow, this microcontroller is fresh new without any bootloader.
Good news! Start from August 2012, this microcontroller is pre-loaded with Optiboot bootloader (Uno 16MHz). This means you can use Arduino code in your own project without using an actual Arduino Board. No programmer is needed anymore but you still need UC00A and basic circuit. Please select Arduino Uno Board in the Arduino IDE. We are using this microcontroller in our Breadboard Friendly Arduino (BBFuino). Therefore, you can refer to BBFuino's schematic and tutorial for more information. 


hi, is this genuine ic by Microchip ? ( Faris Ikhmal , 24/09/2021 )
Not answered yet.
Hi, I ordered this ATMEGA for my Arduino UNO Rev 3. I burnt the previous one by applying 5A to the board so I replaced the previous IC with this one. However, I still cannot get the code to upload to the board or anything like that. Any possible solution? ( Obaid Rafiq , 21/02/2020 )
Hi, for technical assistance, you may email to support@cytron.io Thanks :)
I bought this IC last week, when I received it and tried to upload coding, I get this error everytime.
avrdude: stk500_getsync(): not in sync: resp=0x00
Which mean, my arduino is not communicate with the computer. Why is this happening?????? When I change it IC atmega with the other IC, I got no error. Which mean, this IC atmega is at fault.
( Fazira Nan, 05/05/2017 )
Hi Fazira, we apologize for the inconvenience. Either the IC is fault or the bootloader is missing. If you have another Uno, you could try to upload the bootloader to the ATmega328P by referring to this tutorial. If you want to get a replacement, please fill up the support form for the warranty purpose. Thanks.
hi, I wanna replace the broken atmega 328p on my arduino UNO with this preloaded bootloader chip, can I just plug and directly upload the sketch into it? Thank you. ( david, 04/05/2015 )

Yup, you can directly replace the broken Atmega328P on Arduino UNO.

Is that mean i must use 16mhz crystal into to make it function normally? ( Sam Chun Wai, 20/04/2015 )

Yes, Arduino UNO uses 16MHz to run as explain in the product description. If you have further inquiry, please do discuss in our technical forum as this section is for short inquiry, thanks :)

hi, do i still need to burn the bootloader into the chip? because it stat already pre-loaded with optiboot bootloader ( sam, 19/04/2015 )

Nop, if you want to use it as Arduino UNO, you do not need to load the bootloader again.

can u provide the schematic diagram for this controller to programmed and run? can u provide some tuturiol or sample coding for this controller? Thank ( Sam, 24/03/2015 )

You can check the scematic of BBFuino, it is using ATmega328, also check the tutorials under the product page, there are plenty of tutorial. Sample code? Arduino has tons of sample code :)
