1.1  Introduction
The STP2002QFP FEPS (Fast Ethernet
®
, Parallel, SCSI) is an ASIC that pro-
vides integrated high-performance SCSI, 10/100 Base-T Ethernet, and a Cen-
tronics compatible parallel port.
1.2   Features
FEPS features include the following:
1.3  Overview
FEPS contains four major blocks: SBus Adapter (SBA), SCSI_Channel,
ENET_Channel, and PP_Channel. Each channel uses the Channel Engine In-
• IEEE 1496 SBus master interface with support for 64-bit mode access
• IEEE 1496 SBus slave interface, 32-bit mode only
• 20 MB/s fast and wide single-ended SCSI using a QLogic FAS366 core
• 10/100-Mb/sec Ethernet on the motherboard
• MII (Media Independent Interface) interface to support external transceivers
• DMA2-compatible Centronics parallel port with a maximum throughput of 4
MB/s
• Supports use on an SBus card device
• Provides a path to an FCode PROM for use on SBus boards
• JTAG support for boundary and internal scan testing
