arduino uno circuit diagram altium atmega328p datasheet

A popular example of this is the Arduino Uno, which has a DIP socket to help replace the ATmega328P-PU MCU when needed.

DIP ICs are commonly used with DIP sockets, which allow the easy replacement of the ICs without re-soldering. DIP28 has two rows of 14 vertical pins, and so on.Īpplications: DIP ICs are easy to handle and are widely used in prototyping applications, like with breadboards. They are commonly referred to as DIPn, where n is how many pins it has. DIPs have a pin pitch of 0.1” or 2.54mm, and are commonly used with breadboards. DIP PackagesĭIPs or Dual Inline Packages are the most popular through-hole IC packages, and has two parallel rows of pins with rectangular housing. Let’s take a look at the different IC packages: I. Some ICs such as DIPs or PLCCs can be placed into a socket for the easy replacement of devices during development. Surface-mount ICs are meant to be soldered directly onto the surface of the PCB, and may be harder to assemble but have the advantage of smaller form factors. Through-hole ICs are easier to work with, because they can be used with breadboards or inserted into a PCB and soldered on the other side. IC packages can either be through-hole or surface-mount. Below is ATmega328P-AU along with corresponding pin diagram:

The corresponding function of the pin is identified from the datasheet.

The dot on the IC shows the first pin, and you count the pins counter-clockwise. Each pin in an IC has a unique function, which you can see by looking at its datasheet. There are many different types of IC packages which differ by size, pin count, pin location and mounting type - surface-mount or through-hole. Pins electrically connect the IC with rest of the PCB. IC Packagesīefore integrated circuits (ICs) are assembled onto the printed circuit boards (PCBs), they are put into packages with terminals called pins (or pads). We have also included some links to popular ICs.

In this blog, we will focus on demystifying different IC packages, so that you can make an informed decision when you select the IC for your next project. ICs are the backbone of electronic devices, and choosing the right IC requires considering factors like price, reliability, performance, and package, among others. Continuing our series on how to select components, we will discuss different IC packages in this blog.
