SATA Controllers
A major goal of the SCS-TRUMPET is to provide
versatile storage solutions. Up to four SATA
channels are passed through from the CPU
carrier card via the side card mezzanine
connector HSE. These ports are in use for on-
board storage options, i.e. the 2.5-inch
SSD/HDD drive, and two M.2 standard
mezzanine modules. The fourth HSE based
SATA channel (to be supported by future CPU
cards), is wired to the optional backplane
connector P3. 6G SATA speed is consistently
supported on the SCS-TRUMPET.
As an option for additional mass storage
attachment, the SCS-TRUMPET can be equipped
with up to two Marvell 88SE9170 PCI Express®
to dual-port 6Gbps SATA controllers, dedicated
to the rear I/O connector P3. Driver software
must be installed prior to usage.
Via P3, these four SATA channels are available
for usage on a custom specific rear I/O
transition module, or by means of a
CompactPCI® Serial backplane together with
SATA based peripheral cards.
USB 3.0 Controller
The HSE and EXP side card mezzanine
connectors comprise up to 6 USB 2.0 ports in
total, passed through from the CPU carrier card
to the SCS-TRUMPET. SuperSpeed USB however
is provided by the on-board TUSB7320
controller, made available across two USB 3.0
front panel jacks for attachment of external
devices. XHCI driver software is available.
As an option, the SCS-TRUMPET can be
equipped with two quad-port TUSB7340
controllers. The additional six USB 3.0 ports are
wired to the backplane connector P3 for
optional rear I/O usage. In addition, some
sideband signals are routed to P5, in order to
control external electronic V
BUS
power switches.
Super I/O Controller
The on-board SIO is accessed via the LPC
interface provided by the EXP side card
mezzanine connector. The SIO comprises legacy
I/O circuitry such as UART (COM), PS/2 (keybord
and mouse), and parallel printer (LPT). Most
pins also also usable as universal GPIO ports.
The legacy signal group is available for optional
rear I/O via the backplane connector P4.
The four serial interfaces (UART) of the SIO are
optionally available for front panel I/O (EIA-232
D-Sub), and alternatively for rear I/O usage (TTL-
level). Do not use both options simultaneously
in order to avoid signal interference. Suitable
RS-232 or RS-485 transceivers for rear I/O must
be externally supplied. The PS/2 port may be in
use also on the C32-FIO front panel module.
