The LSI53C885 is a PCI SCSI controller manufactured by LSI Computer Systems. It provides a high-performance interface between a computer's PCI bus and SCSI devices such as hard drives, tape drives, and scanners. It was commonly used in servers and workstations to provide reliable and fast data transfer to SCSI peripherals.

Applications

• Servers
• Workstations
• SCSI hard drive controllers
• SCSI tape drive controllers
• SCSI scanner interfaces

Features

• PCI bus interface
• SCSI-2 compatibility
• Bus mastering capability
• Supports synchronous and asynchronous data transfer
• Integrated DMA controller

Benefits

• High-speed data transfer between the PCI bus and SCSI devices
• Improved system performance due to bus mastering
• Compatibility with a wide range of SCSI peripherals
• Reduced CPU overhead due to integrated DMA
• Reliable data transfer

Additional Details

The LSI53C885 supports data transfer rates up to 10 MB/s. It uses a 32-bit PCI interface and supports both synchronous and asynchronous SCSI data transfer. The integrated DMA controller allows the controller to transfer data directly to and from system memory without CPU intervention, significantly improving performance. The chip is typically packaged in a PQFP package. Driver support is generally available for various operating systems, including Windows and Linux. The specific datasheet should be consulted for details on pinout, timing characteristics, and configuration options.
