Which microcontroller is used in Arduino Uno?
The microcontroller used in the Arduino Uno is the ATmega328P , made by Microchip (formerly Atmel). Here's a more detailed breakdown: Core Microcontroller: ATmega328P Architecture: 8-bit AVR RISC Clock Speed: 16 MHz (crystal oscillator on the Uno board) Flash Memory: 32 KB (0.5 KB used for bootloader) SRAM: 2 KB EEPROM: 1 KB Digital I/O Pins: 14 (6 can be used as PWM outputs) Analog Input Pins: 6 Operating Voltage: 5V Important Supporting Chips on the Uno Board While the ATmega328P is the "brain," the Uno has other important chips: USB-to-Serial Converter: ATmega16U2 (or ATmega8U2 in older revisions) Handles USB communication with your computer Converts USB signals to serial that the main microcontroller can understand Voltage Regulator: NCP1117ST50T3G Regulates incoming voltage to stable 5V and 3.3V Different Uno Versions It's worth noting that there have been some variations: Uno R3 (...
