Description

The ATmega328 is a popular microcontroller chip manufactured by Atmel, now a part of Microchip Technology. It is commonly used in various electronic projects and is the core microcontroller in the Arduino Uno board.

Here are some key features of the ATmega328 microcontroller in DIP-28 (Dual Inline Package with 28 pins) configuration:

Architecture: The ATmega328 is based on the Modified Harvard Architecture, featuring an 8-bit RISC (Reduced Instruction Set Computing) CPU.

Flash Memory: It has 32 KB of Flash program memory for storing the user's program.

SRAM: The microcontroller has 2 KB of SRAM (Static Random-Access Memory) for data storage during program execution.

EEPROM: It includes 1 KB of EEPROM (Electrically Erasable Programmable Read-Only Memory) for non-volatile data storage.

Clock Speed: The typical clock speed is 16 MHz, although it can operate at lower frequencies as well.

I/O Pins: There are 23 General-Purpose I/O (GPIO) pins that can be used for digital input/output or various communication protocols.

Analog Inputs: It features 6 analog inputs for analog-to-digital conversion.

Communication Interfaces: It supports serial communication through USART, SPI (Serial Peripheral Interface), and I2C (Inter-Integrated Circuit).

Timers and Counters: The ATmega328 includes several timers/counters for various timing and PWM (Pulse Width Modulation) applications.

Power Supply: It operates at a voltage range of 1.8V to 5.5V, making it versatile for different power supply scenarios.

Programming:

The microcontroller is programmable through various methods, including in-circuit programming using ISP (In-System Programming) or a bootloader.

These are great, I'm glad I jumped into them

I originally only programmed tiny microprocessors. I was inspired by 'Make: AVR Programming' by Elliot Williams to give the atmega328p a try. The chip worked great. The included sockets are a nice bonus.If you search instructables for cscientific, you should find one for building the programming board and one for building the prototype including source code for programming the atmega.
