1.1 Main Functions
The following sections explain the main functions of the cPCI-6841.
CPU Support
The cPCI-6841 SBC is designed for the Intel® Pentium® M and
Celeron® M Processors. The standard cPCI-6841 SBC comes
with CPU socket which can be installed with
µFC-PGA2 package
CPU, with the following options:
X Pentium® M 1.4GHz, 1.6GHz, 1.7GHz, 1.8GHz, and 2.0GHz
X Celeron® M 1.3GHz
The Low Voltage (LV) or Ultra Low Voltage (ULV) version of the
Pentium® M or Celeron® M Processors, which are in
µFCBGA2
packages, can also be mounted on the cPCI-6841 SBC. However,
µFCBGA2 CPU support is reserved for OEM programs only. The
possible CPU options include:
X LV Pentium® M 1.1GHz, 1.2GHz, 1.3GHz
X ULV Celeron® M 600MHz
CompactPCI Bus Interface
The TI Technology PCI-2050 is a universal PCI to PCI bridge and
is used to implement the system slot on the cPCI-6841. The cPCI-
6841 CompactPCI bus supports 32-bit/33 MHz PCI.
PCI Mezzanine Card (PMC) Interface
The cPCI-6841 supports one PMC slot at 32-bit/33 MHz PCI,
providing expansion capability and flexibility for varieties of
applications.
IDE and CompactFlash Interfaces
The cPCI-6841 supports dual Ultra ATA100 IDE channels. Pri-
mary IDE is implemented on the cPCI-6841 and Secondary IDE is
routed to the backplane via the J3 connector. A 44-pin connector
for 2.5 inch IDE drives is reserved on the Primary IDE interface.
