4.1.1 Memory

The main memory array contains one channel of 72-bit wide DDR3L SDRAM, with
optional 2 GB, 4 GB, or 8 GB density. The system memory controller is integrated in the
G-Series SoC processor. A Serial Presence Detect (SPD) EEPROM, attached to the
internal SMBus, provides memory configuration information to the boot firmware.
Memory displays as a single-rank (2 or 4 GB) or dual-rank (8 GB) unbuffered DIMM.
The SPD chip also contains a temperature sensor physically located near the memory
array, allowing the refresh-time adjustments required for high-temperature operation.

4.1.2 Digital Display Interface

The mCOM10-L1500 supports two simultaneous video outputs with multiple modes. The
G-Series SoC integrates the new generation Radeon Sea Islands GPU, which supports
DirectX 11.1. There is no independent memory dedicated to the GPU video frame buffer
so a portion of main memory must be reserved for this purpose. Two digital video outputs
are provided. Analog video is not used.

4.1.3 PCI Express

The G-Series SoC hosts two PCI Express (PCIe) root complex ports. Four ×1
general-purpose PCIe lanes are wired to the COM Express connector, and support Gen1
(2.5 Gbps) and Gen2 (5 Gbps) speeds. One lane of a ×4 PCIe port is wired to an on-board
Ethernet controller, while the remaining three lanes are unused.
