The IC product code, also known as the manufacturer code or part number, is a unique identifier assigned to integrated circuits ICs by their manufacturers. These codes typically consist of alphanumeric characters and vary in length depending on the manufacturer's conventions. They serve to differentiate one IC from another and provide information about the specific model, characteristics, and manufacturer of the IC. While they are intended to be unique identifiers, there can be cases of overlap or similarities between different manufacturers' codes. The numbers on an integrated circuit IC typically refer to the part number or manufacturer code, which provide information about the semiconductor, use, type, make, and other characteristics of the IC.

Integrated circuit marking codes method of identifying ICs has been used in Europe in various forms since the s. HelloSBKenn Thank you for contacting us, which part are you looking at to identify. These are standardized only within a manufacturer, but still may be useful if a designer can be sure of their supplier options.

Integrated circuits ICs come in many variants and are available from many manufacturers. ICs with similar functions can look very different, while ICs with different functions can look similar. The internal structure and mechanical tolerances of ICs can also be quite varied, and choosing the wrong IC can be detrimental to an electronic design. Engineers and designers need a clear way to differentiate between ICs for their projects. IC manufacturer codes give designers this information, allowing them to be confident in their component choices. IC manufacturer codes are identifying codes placed on integrated circuits by electronics manufacturers. Although IC manufacturer codes are meant to be unique, this is rarely the case.

Last updated: July 3, It was about the same length and weight as two to three double-decker buses and contained 18, buzzing electronic switches known as vacuum tubes. Despite its gargantuan size, it was about a billion times less powerful than a modern laptop—a machine about times smaller. If the history of computing sounds like a magic trick—squeezing more and more power into less and less space—it is! What made it possible was the invention of the integrated circuit IC in

Integrated circuit marking codes

This data base is only a couple of years old judging from the Wayback Machine, but seems to be fairly exhaustive and can be found referenced in quite a few electronics forums. Unlike their larger SMD siblings, these chips in question are so small that there is no room to print the entire part number on the device. Instead, the standard practice is for manufacturers use an abbreviated code of just a few characters. And just because it is standard practice does not imply the marking codes themselves follow any standard whatsoever. Several sites like the one [JohnK] found have been around for years, and adding yet another database to your toolbox is a good thing. But none of them will ever be exhaustive. Just finding the part marking information for a known chip can be difficult. Some manufacturers put it clearly in the data sheet, and some refer you to other documentation which may or may not be readily available. And some manufacturers ask you to contact them for this information — presumably because it is dynamic changes from time to time.

The first digit describes the component type, followed by a letter describing whether or not the component has been formally registered. This book includes now This is not an exhaustive list but it gives a good overview of the prefixes electronics designers will see most often. Pinout Diagram: The standard pinout diagram for the IC is as follows:. These are standardized only within a manufacturer, but still may be useful if a designer can be sure of their supplier options.

Register today to start searching the right components for your next design. This allows for more extensive or complex programs to be stored externally and loaded into the IC as needed. One-Time Programmable OTP or Masked ROM: Certain ICs, particularly those used for security purposes or in applications where firmware should not be modified after manufacturing, may have their programming permanently set during the manufacturing process.

The IC product code, also known as the manufacturer code or part number, is a unique identifier assigned to integrated circuits ICs by their manufacturers. In-circuit programming allows for convenient updates and modifications to the firmware or configuration of the IC without needing to remove it from the circuit. We have more than Integrated circuits ICs come in many variants and are available from many manufacturers. Determine the Calendar Year: The first two digits of the date code represent the last two digits of the calendar year in which the IC was manufactured. This mark indicates the orientation of the IC, often denoting Pin 1 or another specific reference point. Here are the key characteristics of the IC:.
