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. These codes are used to identify and select the appropriate component for a circuit.

Could you please provide a photo of the part with the markings? Related Posts. This series encompasses a wide range of digital logic ICs that perform various functions such as gates, flip-flops, integrated circuit marking codes, multiplexers, and more.

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.

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.

All Rights Reserved. For example, if the date code reads "," it means the IC was manufactured in the 43rd week of the year. Some companies have much more detailed internal hardware codes than others and those codes are constantly updated to reflect industry changes. Ultra Librarian uses verified IC manufacturer codes to help designers unambiguously identify the components they need. This book includes now Number Counterclockwise: Continue numbering the pins counterclockwise around the IC. Related Posts. Since full IC manufacturer codes are specific to parts and companies, the most common codes in design change often. Now getting a lot of errors. I have checked their site and was unable to locate that marking in a QFN package size. Service mode and option. This mark indicates the orientation of the IC, often denoting Pin 1 or another specific reference point. Adjust for the First Week : Manufacturers often consider the first week of the year as the week in which the first Thursday of the year falls.

This article focuses on the JEDEC standards when interpreting codes, but each region has published highly detailed standards. We use cookies to provide our visitors with an optimal site experience. This series encompasses a wide range of digital logic ICs that perform various functions such as gates, flip-flops, counters, multiplexers, and more. Integrated circuit cross reference. Indeed, modern integrated circuits ICs are often programmed using various methods depending on their type and purpose. 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. Select Your Location. IC manufacturer codes give designers this information, allowing them to be confident in their component choices. Designers may need to be aware of multiple manufacturer code standards, especially if a company has international ties. They are encapsulated in plastic dual-in-line packages DIPs with a specific pin configuration, such as pin, pin, or pin DIPs. How did you find it? Related Posts. Knowing the proper code for a component is vital to selecting the right parts for a project and finding reference datasheets. I looked at every SMD list I could find. ICs with similar functions can look very different, while ICs with different functions can look similar.
