Integrated circuit marking codes

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, integrated circuit marking codes. 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, integrated circuit marking codes 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 trick was the one Jeff showed above.

Integrated circuit marking codes

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. Many electronics manufacturers use the same manufacturer prefixes, and multiple standards exist for codes, depending on the region of the world a company resides in. Knowing the proper code for a component is vital to selecting the right parts for a project and finding reference datasheets. Designers may need to be aware of multiple manufacturer code standards, especially if a company has international ties.

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.

Different IC coding standards provide varying amounts of detail concerning a component. Over 2. Europe identifies electronic components with a coding scheme maintained by the European Electronic Component Manufacturers Association. For example, if the date code reads "," it means the IC was manufactured in the 43rd week of the year. Indeed, modern integrated circuits ICs are often programmed using various methods depending on their type and purpose. 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. Depending on the coding scheme, two similar components may have significantly different codes. I have checked their site and was unable to locate that marking in a QFN package size. This is not an exhaustive list but it gives a good overview of the prefixes electronics designers will see most often. Name Required First Last.
