S11W S16D
16-bit I/O interface for Sbus

The S16D is discontinued, and is no longer supported. The information on this page is provided for reference only.

  • Sun SPARCstation compatible
  • Single SBus slot
  • Continuous input or output
  • Rates to 10 megabytes per second
  • Supports Sbus 16-byte burst mode
  • Supports buffered block modes with internal FIFO
  • Programmable control signal configurations
  • 4 gigabyte DVMA addressing
  • Device drivers for Solaris 1.x (SunOS 4.1.x) and Solaris 2.6+ (SunOS 5.x)

The S16D provides a high-speed, 16-bit, continuous data I/O interface for SBus computers. This interface is used for computer to device connection where speed and continuous processing are essential. The S16D will support transfers of 10 megabytes per second to computers or devices which can support that role.


The S16D can be used to enable data transfer to or from the SPARCstation. Typical applications include A-D and D-A converters, and video systems.


A standard SunOS loadable device driver for the SPARCstation is included with the S16D. The driver provides access to the S16D through standard and the S16D is provided with a minimal FCodes PROM for identification only. User FCode PROMS may be developed for specific applications.
