53C80 Description

Short technical summary and product information.

The LSI Corporation 53C80 is a high-performance SCSI Bus Controller designed to support the physical layer of the Small Computer System Interface (SCSI) bus. It is pin and functionally compatible with the NMOS NCR5380, offering significant improvements in performance and power reduction.

This controller supports asynchronous data transfer rates of up to 4 Mbytes/sec. It features on-chip SCSI bus drivers and can operate in either initiator or target roles. The 53C80 provides flexibility with a choice of programmed I/O or various DMA modes, including handshake or wait state DMA interlock. It also includes internal hardware for arbitration and can monitor various error conditions.

The L5380/53C80 is available in multiple package styles, including 40/48-pin Plastic DIP, 48-pin Sidebraze Hermetic DIP, and 44-pin Plastic LCC J-Lead. Its low power CMOS technology and enhanced features make it a suitable replacement for older SCSI controllers, offering improved transfer rates and reduced power consumption.
