Industrial Controller with Data Acquisition & 46 PWM

Lifecycle: De-emphasized | Released: November 2011

The TS-7520-BOX is a multi-functional industrial controller based on a Cavium Arm-based SOC that provides industrial grade opto-isolated input/output channels. Other features include Ethernet, USB Host, CAN, RS-232, RS-485, ADC, DAC PWM, Counters

  • Muli-funcational industrial controller
  • Supports DIN wall mount
  • Rugged, low cost plastic enclosure
  • Includes data aquisition driver (daqctl)
$305 (Qty. 100) $344 (Qty. 1)
No minimum order quantity on standard products.

The TS-7520-BOX features a 250MHz Cavium with an Arm922T™ core and a 8000 LUT Lattice FPGA. With 64MB RAM booting from one of two MicroSD card slots, the TS-7520-BOX is a powerful and extremely reliable industrial embedded solution. External devices can connect to the TS-7520-BOX via Ethernet, USB, RS-232, RS-485, or CAN. The TS-7520-BOX is powered by a DC power supply anywhere in the 8-28V range. Dual internal microSD slots allows for expanded storage.

The RJ-45 connectors provide the following interfaces:

  • 2 opto-isolated digital inputs (0-30 VDC)
  • 10 High-side 500 mA Outputs
  • 2 High-side 1 A Outputs
  • 34 Low-side 500 mA Outputs
  • 8 analog inputs (0-30V, 0-5V, 4-20mA)
  • power supply input (8-28V)

The digital inputs can act as edge counters, quadrature decoders, ADC triggers, or simple inputs. The outputs can be used for simple outputs or PWMs. The TS-7520-BOX also provides an internal header with the following functionalities:

  • Debug console
  • DIO
  • UARTs
  • SPI
  • I2C

Rugged Plastic Enclosure

Available with a DIN mount, the enclosure makes the TS-7520-BOX ready for immediate deployment. The enclosure label clearly identifies the pinouts on the RJ-45 connectors.

Opencore FPGA

The TS-7520-BOX FPGA programming is open-source. If the many features provided in the standard load don't meet the needs of your application, you can modify the FPGA logic or hire embeddedTS to do so for you.

Upon bootup, the default software automatically checks for an FPGA bitstream and loads it if it is present, overriding the default FPGA programming. To create your own bitstream, you need only the following resources:

See here for more instructions on FPGA development.


The TS-7520 SBC boots to Linux 2.6.24 from a microSD card.  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-7520-BOX software features include:

  • Boots Linux 2.6.24 out-of-the-box in less than 3 seconds (to a shell prompt).
  • MicroSD card pre-installed with Debian Linux distribution.
  • Un-brickable design ensures 100% recoverability from microSD card.
  • Startup Linux mini-root scripts allow flexible root and backup filesystem selection (microSD, NFS, USB flash) as well as software field upgrade support.

Data Acquisition

The TS-7520-BOX ships with a full-featured, open source data acquisition driver utility called daqctl. This utility gives full control over a wide variety of TS-7520-BOX hardware features including ADC, PWMs, quadrature, counters, and timestamped glitch detection. The FPGA can easily be programmed to interrupt the CPU under a wide variety of external conditions. A data acquisition network service is also supported, allowing for software control on a remote system.

Linux OS and Debian Support

embeddedTS's TS-7520-BOX 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 vision. 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 functionality are handled by user-space utilities. The Linux kernel includes driver support for on-board hardware, enabling quick time to market of end-users applications. Examples and source code 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-7520-BOX functions are included. In addition, the full Debian binaries and services are available from the initial ramdisk.

The TS-7520-BOX SBCs are configured to load Debian Linux from the microSD card during boot up time.  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-7520-BOX utilizes a Lattice XP2-144 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-7520-BOX 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..)
