Devices’ Features and Data Paths South Bridge
110 PENT/ATCA−717
Secondary Parallel ATA Interface
The secondary parallel ATA interface is connected to an on−board CompactFlash
connector which supports CompactFlash cards of type I and II. An inserted card runs in
true IDE mode and is master on the secondary parallel ATA interface.
a
USB Interfaces
The South Bridge provides four USB interfaces. Two are routed to the blade ′s face plate
and two to the rear transition module. All interfaces are compliant to the USB 2.0
standard.
a
PCI Interface
The South Bridge provides a 32−bit/33 MHz PCI interface that is compliant to the PCI 2.2
specification. Up to four external PCIbus master devices are supported and a 3.3V
signaling level is used.
Serial ATA Interfaces
The South Bridge provides two Serial Advanced Technology Attachment (SATA)
interfaces which are compliant to the SATA 1.0 specification and support a data transfer
rate of up to 1.5GByte/s. One interface is routed to the Zone 3 connector and is accessable
via an installed RTM. One interface is routed to an on−board SATA connector to which a
SATA hard disk can be connected.
a
Serial RS232 Interfaces
The South Bridge provides two serial full−duplex RS232 interfaces. Supported baud rates
are: 600, 1200, 2400, 4800, 9600, 19200, 38400 and 115200 kb/s. Both serial interfaces are
+/− 15 KV ESD protected.
Both interfaces correspond to the blade ′s serial interface ports 1 and 3. Serial interface port
1 is routed via a zone 3 connector to an installed RTM. Serial interface port 3 is accessible
via an installed CMC module. The BIOS maps the serial interfaces ports to the desired
I/O addresses (COM ports) and interrupts.

LPC Interface
The South Bridge provides a 4−bit wide Low Pin Count (LPC) interface running at 33
MHz. It has the following devices attached to it:
S Super I/O
