1.1 Introduction
Figure 1-1: SPCIE-C246
The SPCIE-C246 is a full-size PICMG 1.3 CPU card. It has a LGA1151 socket that
supports Intel®Xeon®E3, 8th/9th generation Core™ i9/i7/i5/i3, Pentium® or Celeron®
processors, and it supports four 288-pin 2666MHz dual-channel DDR4 DIMM modules up
to 64 GB.
The SPCIE-C246 provides two GbE interfaces through the Intel®I219LM PHY (with Intel®
AMT 11.0 support) and the Intel®I211AT PCIe controllers. The integrated Intel®C246
chipset supports six SATA 6Gb/s drives with RAID 0/1/5/10 function.
Two USB 3.2 Gen 1 on the rear panel, two USB 3.2 Gen 1 by internal box header, six
USB 2.0 by pin headers, one USB 2.0 by internal Type A connector, three RS-232, one
RS-422/485 and one M.2 M-key slot provide flexible expansion options. High Definition
Audio (HDA) support ensures HDA devices can be easily implemented on the
SPCIE-C246.
