Functional Description
COMX-CORE Series Installation and Use (6806800K11F) 62
4.5 System Memory
The Arrandale ECC processor integrates a dual-channel 72-bit ECC DDR3 controller. The pinout
of DDR3 SODIMM ECC is different with DDR3 SODIMM non-ECC memory. COMX-CORE Series
cannot support ECC and non ECC memory modules at the same time.
There are two 204-pin SODIMM slots onCOMX-CORE Series. One slot is located on the top of
the module with a height of 6.5 mm. Another is located at the bottom of the module with a
height of 4.0 mm.
COMX-CORE Series supports the following:
 COMX-CORE-510/710/750 (non-ECC) - Two DDR3 800/1066 64-bit SO-DIMM sockets.
Maximum memory capacity is 8GB non-ECC memory
 COMX-CORE-312/512 (ECC) - Supports two DDR3 800/1066 64-bit SO-DIMM sockets.
Maximum capacity is 8 GB ECC memory.
4.6 SMBus Interface and Devices
There are three SMBus interfaces on Ibex Peak-M. The following devices connect to the SMBus:
 The SPD of two DDR3 non ECC SODIMM
 CK505M clock chip
 8 KB COM Express serial EEPROM for vendor information
 LM96080 voltage measurement device
 SMbus interface routes to COM Express connector
 PCA9557 for GPIO application
