The TS-7250 is a compact, full-featured Single Board Computer
(SBC) based upon the Cirrus EP9302, which provides
a standard set of onboard peripherals. The EP9302 features
an advanced Arm9™ core design with MMU.
TS-7250 includes software power consumption control for onboard
peripherals, making this board ideal for use in power sensitive designs,
such as battery-powered systems. In addition, the TS-XDIO standard feature can be replaced by either 2
extra serial ports or an SD card socket, which enables fast boot to Debian Linux from an SD card.
The TS-7250 specifically targets
ultra low power applications such
as solar or battery powered devices.
It features an optional high-precision
temperature sensor and the onboard
ADC measures input voltage for battery
or solar applications. The default
configuration with no ethernet consumes
½ Watt of power. A small UPS battery
(12V / 7.2Ah) can power this board
for up to 172 hours! Since the CPU
has continuously variable on-chip
PLLs, it could survive even longer
if you allow its internal clocks
to slow down. Low power also means
low heat - feel free to put this
board in the most confined of places
as it needs neither fan nor heatsink
across its entire temperature range
(-40° to +70° with CPU at 200MHz; -40° to +85°C with CPU at 166MHz or lower).
The TS-7250 features a high efficiency
switching-mode power supply, which
enables variable input voltage anywhere
from 4.5 to 20V DC. In addition,
it includes software controlled switches
that are able to turn off USB 5V
power, LCD power, ethernet PHY, RTC,
and RS-232 level converters when not
in use, reducing the power
consumption even more. As with all our Arm-based
products, low board complexity, low
component count, and low power/heat
make for an extremely reliable embedded
Users can pre-configure the TS-7250
SBC for optimum performance to meet
their applications' needs. The TS-7250 comes
standard with the TS-XDIO feature,
which provides more control functions
for data acquisition and control systems.
The TS-XDIO may be replaced by either
the SD card socket option (OP-SDSOCKET)
or the 2 extra TTL serial ports option
The SD card socket allows more flash memory to be added via SD flash cards. The TS-7250 is also able
boot to Debian Linux from an SD card.
The 2 extra TTL serial ports option
enables interfacing to external hardware.
It is important to note that these
options cannot be simultaneously
selected, meaning that only one of
these features can be
selected for a single TS-7250 configuration.
embeddedTS's TS-7250 Arm based Single Board Computers (SBCs) are compatible with a wide range of Operating Systems (OS's).
The Linux choice is highly recommended and our products are totally integrated with the open-source vision. The Linux OS, TS-Kernel 2.4.26, is
shipped by default with our Arm based SBCs and includes complete driver support for our hardware within the kernel, enabling quick time to market for end-users'
applications. Examples and source codes are also available for downloading.
The embeddedTS Arm based SBCs include the TS-Linux compact embedded OS installed by default in onboard flash memory (8MB, JFFS or YAFFS filesystems).
The eCos/Redboot boot loader is used to open the OS of choice. In addition, the full featured Debian Linux distribution can be used with a network
directory (NFS root) or larger flash drives (256MB), such as Compact Flash, SD cards or USB memory sticks. The Linux system includes a complete
GNU C/C++ embedded development environment installed. In addition, Apache Web Server, FTP, SSH, Telnet and Samba internet services are
available with C/PHP/Perl for embedded CGI development.
The Linux solution for Arm cores is compatible with the RTAI real-time extension, enabling systems with strict timing requirements to be handled with our SBCs. Furthermore, NetBSD has been ported to embeddedTS Arm based SBCs and Java solutions are also available.
