Chapter 1 Product Features

Signals routed to P14 include: narrow SCSI, parallel port, COM1 and COM2 synchronous serial ports, COM3 and COM4 synchronous serial ports, power, and P2 mux signals. The remaining SCSI data lines are routed to P15.

The on-board PCI devices on each module are as follows:

■Winbond PCI-to-ISA Bridge (PIB)

■LSI SCSI device (SYM53C895A)

Configurable Switches

S1 Switch

A 1x4 switch (S1) is provided on each module for configuring GPIO pins 2 and 3. The factory default setting is for Ultra-Speed and Ultra-Wide SCSI. Refer to Table 3-1 on page 16 for the GPIO pin assignments and to Figure 3-1 on page 16 for the default switch settings.

S2 Switch

There is a 1x2 switch (S2) on each module that is in line with the PCI-to-ISA bridge for selecting either AD[11] IDSEL or IDSELB for connection to the Winbond chip, depending on the IPMC module you are using.

Note The S2 is not dependent on either IPMC module. It is dependent on either the MVME5100, MVME5500, or MVME6100 host board. The IPMC modules are shipped configured for these boards.

Details on IDSEL mapping and PCI arbitration assignments for these SBCs can be found in Chapter 3, Programming. An illustration showing the S2 switch settings can be found in Figure 3-2 on page 17.

PCI-to-ISA Bridge (PIB)

The PIB provides the bridging functions between PCI local bus and the ISA local resource bus. The following are a few of the features of the PIB.

SCSI

The SCSI controller is an LSI Logic SYM53C895A device. The SCSI clock frequency is 40 MHz. The SCSI controller features:

■32-bit PCI Interface with 64-bit addressing

■8KB internal SCRIPTS RAM

■Improved PCI caching design (improves PCI bus efficiency)

The SCSI device maintains backward compatibility with the MVME761 rear transition module and P2 adapter card. It is also Ultra-wide capable and has a performance of 40MB/s synchronous transfer rate across a 16-bit bus.
