The SYM53C895 is a PCI-to-Ultra Wide SCSI controller from LSI Logic (now Broadcom). It provides a high-performance interface between a PCI bus and an Ultra Wide SCSI bus, enabling fast data transfer rates for connecting SCSI devices to a computer system. This controller was commonly used in servers, workstations, and high-end storage solutions requiring high-speed SCSI connectivity.

Applications

• Server Storage Solutions
• Workstation Storage Systems
• RAID Controllers
• High-Performance SCSI Host Adapters
• Connecting SCSI Hard Drives
• Connecting SCSI Tape Drives
• Connecting SCSI Scanners

Features

• PCI Interface: Compliant with the PCI bus standard for high-speed communication with the host system.
• Ultra Wide SCSI: Supports the Ultra Wide SCSI standard, enabling data transfer rates up to 40 MB/s.
• DMA Support: Allows for direct memory access, improving data transfer speeds and reducing CPU overhead.
• SCSI Bus Termination: Provides on-chip active SCSI bus termination.
• Automatic Configuration: Simplifies installation and configuration.
• Supports Multiple SCSI Devices: Can connect to multiple SCSI devices on the same bus.

Benefits

• High Data Transfer Rates: Ultra Wide SCSI support enables fast data transfer for demanding applications.
• Reduced CPU Overhead: DMA support offloads data transfer tasks from the CPU, improving overall system performance.
• Simplified System Design: Integrated features simplify the design and implementation of SCSI interfaces.
• Improved System Performance: High data transfer rates and reduced CPU overhead contribute to improved system performance.
• Wide Compatibility: Compliant with industry-standard PCI and SCSI standards, ensuring compatibility with a broad range of devices.

Additional Details

The SYM53C895 requires proper termination and configuration for optimal performance. Its power consumption and operating temperature range are also important considerations for system design. Refer to the device datasheet for specific electrical characteristics, timing diagrams, and configuration details. Requires a 50-pin connector to connect to SCSI Devices.
