53C8xx

The 53C8xx series is a family of SCSI (Small Computer System Interface) controllers developed by NCR Corporation, later acquired by AT&T and subsequently by Broadcom. These controllers are designed to interface between a computer system and SCSI devices such as hard drives, optical drives, and tape drives. The 53C8xx series is known for its high performance and reliability, making it a popular choice for various applications, including servers, workstations, and embedded systems.

The 53C8xx series includes several models, each with different features and capabilities. The 53C810, for example, is a full-featured SCSI controller that supports both SCSI-1 and SCSI-2 standards. It includes a built-in SCSI bus arbiter, allowing it to manage multiple SCSI devices on a single bus. The 53C825, another model in the series, is designed for high-speed SCSI applications and supports the Ultra SCSI standard, offering data transfer rates of up to 40 MB/s.

These controllers are typically used in systems where high-speed data transfer and reliable device communication are essential. They are often integrated into motherboards, expansion cards, or embedded systems to provide SCSI connectivity. The 53C8xx series is also known for its compatibility with a wide range of SCSI devices, making it a versatile choice for various computing environments.

In summary, the 53C8xx series of SCSI controllers is a robust and high-performance solution for connecting SCSI devices to computer systems. Its features, including support for multiple SCSI standards and high data transfer rates, make it a reliable choice for both traditional and modern computing applications.
