Product Summary

The LSI53C875E is a controller. It supports Ultra SCSI transfers, enabling the chip to transfer SCSI data at up to 40 MBps across a 16-bit bus. The LSI53C875E provides full SCSI-2 capabilities and reduces the requirements for system BIOS support with a local memory interface. It also features LSI Logic TolerANT SCSI driver and receiver technology, for reliable operation in all cabling environments. The LSI53C875E is designed to connect gluelessly to the Peripheral Component Interconnect (PCI) bus, and supports PCI extended access cycles, enabling the system architect to take advantage of PCI’s performance potential.

Features

LSI53C875E features: (1)Performs wide high-speed SCSI bus transfers in single-ended and differential mode up to: 40 MBps synchronous (Ultra); 14 MBps asynchronous; (2)SCRIPTS Instruction Prefetch; (3)536-byte buffer allows burst length of up to 128 transfers; (4)Load and store instruction; (5)4 KB static RAM for SCRIPTS instruction storage; (6)32 additional scratchpad registers for user-defined functions.
