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.

Im not sure if TI is the supplier for this part.

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. Manufacturer codes encompass internal hardware identification and human-readable identifiers like component numbers. Different IC coding standards provide varying amounts of detail concerning a component. Some IC manufacturer codes describe the materials a component is made of, while others contain serial numbers.

This article focuses on the JEDEC standards when interpreting codes, but each region has published highly detailed standards. Search Our Blog, integrated circuit marking codes. Reading IC date codes typically involves understanding the format used by manufacturers to encode the manufacturing date of the integrated circuit.

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 It's a neat way of cramming hundreds, thousands, millions, or even billions of electronic components onto tiny chips of silicon no bigger than a fingernail.

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.

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. This is not an exhaustive list but it gives a good overview of the prefixes electronics designers will see most often. The type of IC manufacturer code most commonly encountered is the manufacturer prefix, followed by a serial number. Email Required. All Rights Reserved. Service mode and option. Indeed, modern integrated circuits ICs are often programmed using various methods depending on their type and purpose. Complete the Numbering: Ensure all pins are numbered sequentially, moving around the IC in a counterclockwise direction until all pins are accounted for. A microchip containing an integrated circuit.

Appliance schematic. 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. Online SMD-codes database. Thank you so much! Any help would be appreciated. Part marking is tc5. Some IC manufacturer codes describe the materials a component is made of, while others contain serial numbers. List of IC Manufacturer Codes. This book includes most popular integrated circuits - power final audio amplifiers and for today is the most complete databook in the world. I looked at every SMD list I could find. By understanding this format, you can determine the manufacturing date of the IC based on its date code. These specifications make the IC suitable for a wide range of applications in various electronic circuits.
