1.2 Main Functions
The cPCI-3840 CPU Module is designed for the Intel® Pentium®
M and Celeron® M Processors. The standard cPCI-3840 CPU
Module comes with a CPU socket which can be installed with a
Micro-FC-PGA package CPU, including the following options:
X
Pentium® M 1.3GHz, 1.4GHz, 1.5GHz and 1.6GHz
X
Celeron® M 1.3GHz
The Low Voltage (LV) or Ultra Low Voltage (ULV) versions of the
Pentium® M or Celeron® M Processors in the Micro-FCBGA2
package can also be mounted on the cPCI-3840 CPU Module.
However, Micro-FCBGA package support is reserved for OEM
programs only. The possible CPU options include:
X
LV Pentium® M 1.1, 1.2, 1.3GHz
X
ULV Celeron® M 600MHz
CompactPCI Bus Interface
The Intel® 6300ESB south bridge chipset supports one PCI
33MHz / 32bits interface compliant with the PCI Local Bus Specifi-
cation, Revision 2.2. The throughput of this PCI bus interface is
132 MB/s, and it supports 44 bit addressing using DAC protocol.
The 6300ESB also supports one PCIX 66MHz / 64-bits interface
which is compliant with the PCIX Bus specification, revision 1.0
and is also compliant with the PCI Local Bus Specification, Revi-
sion 2.2. The throughput of this PCIX bus is up to 480 MB/s. It
supports 64-bit addressing on PCI-X using DAC protocol.
IDE Interfaces
The cPCI-3840 supports dual Ultra ATA33/66/100 IDE channels.
The primary IDE is implemented to CompactFlash (CF) interface
and the secondary IDE is connected to a 40-pin slim-type IDE con-
nector. The 6300ESB IDE controller supports both legacy mode
and native mode IDE interfaces. In native mode, the IDE controller
is a fully PCI compliant software interface and does not use any
legacy I/O or interrupt resources. Note that for Ultra ATA100/66
mode operations, the proper cables must be installed.
