The VT82C596B CE is a southbridge chipset manufactured by Via Technologies. The 'CE' likely signifies a specific certification or manufacturing revision. This chipset is typically found in older PCs, handling I/O functions such as PCI bus, IDE/ATA controllers, USB and legacy I/O ports. It would connect to the northbridge, enabling communication with the CPU, memory and graphics.

Applications:

• Legacy desktop computers from the late 1990s and early 2000s.
• Industrial PCs needing older interface support.
• Embedded systems needing support for legacy hardware.

Features:

• PCI bus controller.
• IDE/ATA controller (likely supporting ATA-33 or ATA-66).
• USB support (USB 1.1 likely).
• ISA bus support for legacy peripherals.
• Power management features.

Benefits:

• Enables connectivity between processor and I/O devices.
• Supports older ISA peripherals.
• Cost effective solution for backward compatibility.

Additional Details:

Detailed datasheets are difficult to find. It works with a Northbridge to complete the chipset functionality. The motherboard's documentation will clarify specific capabilities. The 'B' in the name indicates a specific revision.
