ESCRIPTION
The STP2000 Master I/ O Controller is an integrated SBus master device with built-in standard I/ O capabili-
ties for general purpose computing or embedded applications. The STP2000 directly interfaces the CPU
through the system bus, SBus, to three major I/ O channels for peripherals. The I/ O channels include SCSI-II,
ethernet and a parallel port. Together, with the STP2001 Slave I/ O Controller, it provides a complete I/ O
subsystem.
The STP2000 SBus interface is a 32-bit interface that supports both DMA and slave modes. There is data buff-
ering and flow control on each of the I/ O channels. Each channel has access to the SBus through the controller
which is capable of DMA transfers of up to 32-byte bursts. The SBus slave port is used mostly for status and
control.
The STP2000 incorporates an ethernet controller, a Fast 8-bit SCSI-II controller, and a Centronics parallel port
controller in a single package. The SCSI-II channel directly drives external peripherals. The ethernet channel
can be connected to an external transceiver chip that supports twisted pair ethernet or AUI ethernet. The par-
allel port channel can be routed to external transceivers.
