An input/output expansion bus with a 32- or 64-bit width is described in this standard. The SBus is designed for systems requiring a small number of expansion ports. SBus Cards may be connected to a standard SBus Connector mounted on the motherreboard. SBus Devices may also be attached to the SBus directly on the system's motherreboard. The dimensions of the Sbus Card are 83.8 mm by 146.7 mm, making the cards appropriate for small computer systems that make extensive use of highly integrated circuits. The SBus cards are designed to be installed in a plane parallel to the system's motherreboard as mezzanine cards. They are designed to provide connections for devices external to the computer system through an exposed back panel. The form factor is useful in Futurebus+, VMEbus, desktop computers, and similar applications. The SBus has the capability of transferring data rates up to 168 Mbytes/s, depending on the implementation options selected.
