SOM-6868 User Manual 6
Serial Bus

SMBus
Supports SMBus 2.0 specification.

I2C Bus
Supports I2C bus 8-bit and 10-bit address modes - both 100KHz and 400KHz.
I/O

Gigabit Ethernet
On-module Intel i211AT supports IEEE802.3 for 1000BASE-T, 100BASE-TX,
and 10BASE-T (802.3, 802.3u, and 802.3ab). It supports IPv4, IPv6, TCP/UDP,
SCTP, ARP, Neighbor Discovery, and EUI-64.

SATA
Supports 2 ports SATA Gen3 (6.0 Gb/s) and is backward compatible with SATA
Gen2 (3.0 Gb/s) and Gen1 (1.5 Gb/s). Maximum data rate is 600 MB/s. It sup-
ports AHCI 1.3.1 mode (not support IDE mode).

USB3.0/USB2.0
There are 4 USB3.0 ports (5.0 Gbps) and 8 USB2.0 ports (480 Mbps) which are
backwardly compatible to USB1.x. For USB3.0, it supports LPM (U0, U1, U2,
and U3) manageability to save power.

USB3.0

USB2.0

SPI Bus
Supports BIOS flash only. SPI clock can be 50MHz, 33MHz, or 20MHz, capacity
up to 16MB.

GPIO
8 programmable general purpose Input or output (GPIO).

Watchdog
Supports multi-level watchdog time-out output. Provides 1-65535 level, from
100ms to 109.22 minutes interval.

Serial port
2 ports 2-wire serial port (Tx/Rx) support 16550 UART compliance.
– Programmable FIFO or character mode
– 16-byte FIFO buffer on transmitter and receiver in FIFO mode
– Programmable serial-interface characteristics: 5, 6, 7, or 8-bit character

Type 6 OC_01 OC_23 OC_45 OC_67
SoC USB_OC# OC_0 OC_1
USB HUB OC# OC_12 OC_34
Note! OC_23 connects with OC_45 and OC_67 so USB ports 2-7 will have
active over current protection. It is defined like this because the Hub-OC
will not be shown in the OS and the user won’t notice if an overcurrent
condition occurs on port 5-7.
