Product Brief
Overview
The SSC200 is an enclosure management controller
for peripheral storage applications. This device
supports several in-band and out of band

SCSI Applications
The SSC200 supports two mechanisms for
dedicated port enclosure management across a
parallel SCSI bus. An external SCSI controller can
be connected to the SSC200’s DMA interface to
provide a high performance, two-device SES or
SAF-TE solution. No external components are
required with this approach; the SSC200 integrates
both the DMA buffers and control logic. This
architecture provides system designers with a
common platform for various SCSI bus speeds and
