Integrated Circuit Codes and IC Code List

Understanding Integrated Circuit Codes

Integrated circuits (ICs) are the backbone of modern electronics, and each IC comes with a unique manufacturer code that helps engineers and technicians identify and understand the components they are working with.

In this blog post, we’ll delve into the significance of IC manufacturer codes, how they can be interpreted, and provide a list of common IC manufacturer codes used in the industry.

What Are IC Manufacturer Codes

IC manufacturer codes are alphanumeric identifiers assigned to integrated circuits by their manufacturers.

These codes provide critical information about the IC, such as the manufacturer, part number, date of manufacture, and specific characteristics of the component. They are essential for ensuring compatibility and proper functionality within electronic systems.

Importance of Manufacturer Codes

Knowing these manufacturer codes is essential for several reasons:

• Component Identification: Helps quickly identify the exact part and its specifications.
• Compatibility: Ensures the component will work correctly within the intended design.
• Sourcing: Aids in locating the correct part from distributors or manufacturers.
• Documentation: Facilitates finding datasheets and application notes specific to the component.

How Can Engineers Interpret IC Manufacturer Codes

Interpreting IC manufacturer codes can be challenging, as different manufacturers may use different coding schemes. However, most codes follow a general structure that includes:

1. Manufacturer Identifier: A unique prefix or symbol representing the manufacturer.
2. Part Number: A series of numbers and letters indicating the specific model of the IC.
3. Date Code: Information about the production date, often including the year and week of manufacture.
4. Additional Information: Sometimes codes include other details like batch number, package type, or revision level.

Engineers typically refer to datasheets provided by manufacturers to accurately decode and understand these identifiers. These datasheets contain comprehensive details about the IC, including its specifications, pin configuration, electrical characteristics, and application notes.

STMicroelectronics (STM)

Example: STM32F103C8T6

• STM32: Series (Microcontroller family)
• F103C8: Specific model and memory size
• T6: Package type and temperature range
