82801

82801 is a designation for a family of Intel® I/O Controller Hub (ICH) chips. These chips were designed to integrate various I/O functions for personal computers and servers. The 82801 series typically handled tasks such as Universal Serial Bus (USB) control, Serial ATA (SATA) and Parallel ATA (PATA) storage interfaces, AC'97 or High Definition Audio, and networking capabilities. They were a crucial component of Intel's chipsets, working in conjunction with the Northbridge (often referred to as the Memory Controller Hub or MCH) to manage communication between the CPU, memory, and peripherals.

Over time, the 82801 family evolved through numerous revisions, with each iteration introducing new features and improved performance. For example, later versions of the 82801 ICH incorporated support for faster USB standards like USB 2.0 and USB 3.0, more advanced SATA interfaces, and improved audio codecs. The specific capabilities and numbering within the 82801 series, such as 82801BA, 82801CA, 82801DB, 82801GB, and many others, denoted different feature sets and generations. These chips were commonly found in motherboards for Intel processors and played a vital role in the overall functionality and connectivity of personal computer systems for many years.
