Arduino Series (Lesson 2) - What is Microcontroller & Atmega 328P microcontroller ?

A microcontroller is a compact integrated circuit designed to govern a specific operation in an embedded system.

A typical microcontroller includes a processor, memory and input/output (I/O) peripherals on a single chip.

It has pins that can perform digital and analog operations. They are available with various architectures such as 8 bit ,16 , bit ,32 bit and 64 bit.

ATMEGA328

• ATmega328 is an 8-bit and 28 Pins AVR Microcontroller, manufactured by Microchip, follows RISC Architecure and has a flash type program memory of 32KB.
• It has an EEPROM memory of 1KB and its SRAM memory is of 2KB.
• It has 8 Pin for ADC operations, which all combines to form PortA ( PA0 – PA7 ).
• It also has 3 builtin Timers, two of them are 8 Bit timers while the third one is 16-Bit Timer.
• You must have heard of Arduino UNO, UNO is based on atmega328 Microcontroller. It’s UNO’s heart. 💖
