The TS-7553 features a 250MHz Cavium Arm922T™-based CPU and a 5000 LUT Lattice FPGA.
With 64MB RAM and a bootable 256MB on-board flash drive with our new XNAND
technology, the TS-7553 is a powerful and extremely reliable embedded solution.
External devices can connect to the TS-7553 via Ethernet, XBee radio socket (point to point, unlike the Zigbee which supports mesh networks),
USB host, USB device, or I2C ports, as well as DIO, UARTs, CAN Bus, DMX,
and SPI which are implemented in the standard FPGA load.
Does your application require custom real-time logic such as non-standard
bus interfaces, PWM outputs, quadrature decoding, pulse timing, or digital
counters? embeddedTS can integrate that functionality into a custom
TS-7553 FPGA configuration for an elegant and affordable solution.
The standard TS-7553 configuration implements the following features:
- 4 XUARTs* (2-RS232, 1-RS485, and 1 TTL level to Xbee socket)
- 1 CAN Bus
- SPI Support
- I2C Support
- DMX Support
- Watchdog Timer
- Up to 11 DIO Lines
- Battery Backed RTC
- XBee Radio Socket
- Temperature Sensor
- Designed to fit in an optional low-cost plastic enclosure
- Multipurpose Reset/Script Button
TS-7553 Power Consumption
The TS-7553 requires about 3.2 Watts of power (642mA @ 4.98V) for normal operation and will require more if connecting USB devices,
a larger microSD card, or XBee radio. For this reason, it is recommended
to power the device at 5-12V input via barrel connector or 2 pin terminal
Differences between TS-7553 and TS-7552
The TS-7553 was released April 2010 and is a smaller form factor and cost
reduced version of the TS-7552 without the extra USB ports. It was designed to
be mated with an inexpensive plastic enclosure and serve as a standalone
general purpose embedded server.
embeddedTS XNAND technology is an ultra reliable and
industrial grade user-space device driver that uses Reed-Solomon codes,
extra checksums, and a RAID based technique to allow any Linux filesystem
to be used with confidence on SLC NAND flash. Our TS-BOOTROM can also
boot from XNAND for an ultra-reliable bootup. Please refer to the
XNAND whitepaper for more
* embeddedTS XUART core is an extended UART core
supporting 7, 8, 9, or 10 bits per character, Tx and Rx FIFOs 256+ characters
deep, and accurate measurement of idle and busy times. These ports support
advanced protocols such as DMX/RDM.
The TS-7553 SBC boots to Linux 2.6.24 from either a microSD Card or
on-board XNAND drive. The 256MB on-board XNAND drive is enough to store
a bootable kernel image, initial ramdisk image, and a minimal version of
Debian "Lenny" Linux. Storage memory can be expanded through the microSD
card socket. A bootable microSD card must contain a Linux kernel image, a
initial ramdisk image and a valid Linux root filesystem. The fast Linux bootup
solution was optimized for speed and includes kernel, initrd, and filesystem
(Busybox) tweaks. Since this board boots to an initrd (initial ram disk)
with a read-only mounted filesystem, it is possible to have something other
than a shell prompt running after bootup by editing the /linuxrc shell script
on the initrd. Additional TS-7553 software features include:
- Boots Linux 2.6.24 out-of-the-box in less than 3 seconds (to a shell
- MicroSD card pre-installed with minimal Debian "Lenny" Linux
- Un-brickable design ensures 100% recoverability from MicroSD card in
case of onboard XNAND drive erasure.
- Startup Linux mini-root scripts allow flexible root and backup
filesystem selection (microSD, NFS, USB flash) as well as software field
Linux OS and Debian Support
embeddedTS's TS-7553 Arm®-based Single Board Computers (SBC) 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
The boards ship with Linux 2.6.24 kernel running out-of-the-box. There is no
proprietary source code in the kernel since all the hardware specific
functionalities are handled by user-space utilities. The Linux kernel includes
driver support for on-board hardware, enabling quick time to market of
applications. Examples and source codes are also available for downloading.
The compact initial ramdisk filesystem is based on Busybox and uClibc and is
improved for performance and flexibility. Specific Linux scripts and utilities
that handle the TS-7553 functions are included. In addition, the full Debian
binaries and services are available from the initial ramdisk after mounting the
The TS-7553 SBCs are configured to load Debian "Lenny" Linux from
the on-board XNAND drive or microSD card during boot up time. The on-board
XNAND drive uses a minimal Debian "Lenny" Linux distribution that has been
compacted to fit in the 256MB space and leave about 70MB free for the user
and includes utilities such as apt-get for installing and removing programs.
The microSD card uses a full featured Debian "Lenny" Linux distribution which
includes a complete GNU C/C++ embedded development environment. In addition,
Apache Web Server, FTP, SSH, Telnet and Samba network services are available
with C/PHP/Perl for embedded CGI development.
CAN Bus Support in User Space
The TS-7553 utilizes an SJA1000C-compatible FPGA core out of the box complete
with documentation and sample code.
The sample code provides a simple utility to send/receive CAN packets and perform
useful and common functions with the CAN bus from userspace. Additionally, this
sample code includes network CAN service and can be automatically started on
TS-7553 bootup which makes the writing of CAN enabled applications even simpler
and furthermore allows for the possibility of development in languages other
than C (Java, Python, etc..) and on systems other than the local Linux SBC
(Linux/x86, Windows, etc..)
