The TS-7390 is a compact full-featured Single Board Computer (SBC) based upon the Cirrus EP9302 200MHz ARM9 CPU, which provides a standard set of on-board peripherals. This product features an on-board FPGA with a dedicated 8MB RAM Framebuffer and a 800x480 video core. The TS-7390 has specific connectors and FPGA programming to drive the 7" touchscreen on the TS-TPC-7390. Technologic Systems engineers can design modifications for other LCDs. Please call us with inquiries about customizing the TS-7390 for your project.


The TS-7390 single board computer powers the TS-TPC-7390 application kit. The TS-7390 features a multi-purpose 200MHz ARM9 CPU. It allows for development of multi-function embedded applications through its multiple peripheral interfaces, which include on-board RAM, NAND flash, dual 10/100 Ethernet ports, dual USB 2.0 hosts, serial ports, SD card socket, A/D channels, digital I/O lines, temperature sensor, real time clock, audio codec and speaker, video framebuffer, touchscreen, and LCD video interfaces.

The 40-pin header provides the following features:

  • I2C Bus and SPI Bus
  • 4 12-bit ADC
  • 6 Latched Outputs
  • 7 Buffered Inputs
  • 3 Digital Inputs/Outputs
  • 1 Console COM Port (requires TS-9445 mini-peripheral for RS-232 levels)
  • External Reset, Power, Ground, Frame and JTAG signals

The default load for the 5K LUT Lattice XP2 FPGA provides additional peripherals, such as SD Card socket, extra serial ports and a 800x480 Color TFT-LCD video core. In addition, the FPGA provides an 8-bit multiplexed expansion bus for inclusion of application-specific daughter cards, with the connector pins connected straight to the FPGA.

The TS-7390 engine is extremely rugged and reliable. Temperature operation is fanless and range is industrial standard at lower CPU speeds. Power input range is flexible from 5VDC to 28VDC. The power supply for the LCD and the LCD back-light are controlled via software.

The TS-7390 provides multiple COM ports using both TTL (2 total) and RS-232 levels (4 total). Two optional RS-485 ports are also available with DMX/RDM support. The EP9302 processor provides two COM ports (TTL Console at the JTAG header and RS-232 at COM1 header). The remaining COM ports are provided by the FPGA through the proprietary TS-UART core and are 9-bit serial capable.

LCD-Ready Embedded Computer

The TS-7390 is designed specifically as the engine for the TS-TPC-7390. The connectors are not general purpose and will not work with most LCDs, so we do not generally sell the TS-7390 as a stand alone board. If you have an interest in using the TS-7390 in your project, please call us for information about pricing or product customization. Also, for customers looking for a custom SBC solution for their LCD+TouchScreen interfaces of choice, we recommend customization of the TS-7350 or TS-7370 LCD-Ready FPGA computer. Contact Technologic Systems should you need more information about custom LCD FPGA designs or assistance with LCD integration.

The TS-TPC-7390 Application Kit

The TS-TPC-7390 is a low-cost, industrial-grade WVGA touchscreen computer with audio codec and speaker. Utilizing a low-power EP9302 ARM9 CPU, it requires no fans or heat-sinks. Reliability is enhanced through entirely solid-state operation with no moving parts. The rugged aluminum support elegantly frames the 7-inch TFT LCD, making an ideal solution for mounting on a wall or cabinet. The computer unit is mounted to the back of the panel, providing access to a wide variety of connectors including 2 10/100BASE-T Ethernet port, 2 full-speed USB ports, DIO and serial ports. The unit runs Debian Linux 2.6 and Debian Sarge out of the box and is suitable for a wide range of HMI-type and simple GUI applications.


The TS-7390 SBC boots to Linux 2.6 from an SD Card using the proprietary TS-SDBOOT bootup firmware residing in FPGA ROM memory in about one second, depending on the SD Card speed and brand. The board can also boot from on-board NAND flash using the TS-NANDBOOT firmware in about the same time. The state of jumper 1 (JP1) controls whether the board boot from NAND or SD.

A valid bootable media (SD Card or NAND flash) must contain a Linux Kernel image, a initial ram disk image and a valid Linux root filesystem. The ultra-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-7390 software features include:

  • Boots Linux out-of-the-box in about one second (to shell prompt, depending on SD card).
  • SD card/NAND flash pre-installed with standard Debian Linux distribution.
  • Startup Linux mini-root scripts allows flexible root and backup filesystem selection (SD, NAND, NFS, USB flash) as well as software field upgrade support.
  • Linux "bootload" program allows booting of Linux kernels and other OS's from within Linux itself.
  • Includes FrameBuffer, Video, TouchScreen, Mouse and Keyboard Linux drivers.
  • GUI application development through X Windows Systems (x.org).
  • Other GUI library packages possible/provided.

Bootloader Un-brickable Design

The TS-7390 bootstrap combines FPGA hardware logic, specific boot-up firmware and Kernel tweaks to ensure fast boot time, security, and high board recoverability:

  • Linux-based bootloader boots Linux 2.6 kernel to shell prompt in about one second from SD card or onboard flash. A Linux bootload utility is available to boot any other Kernel or Operation System image from Linux shell prompt.
  • Un-brickable design ensures 100% recoverability from SD card in case of onboard flash erasure.
  • Full Debian linux can be installed on on-board Flash from a USB flash dongle or SD Card, eliminating the need to use miniaturized niche embedded Linux distributions or blast/boot boards.
  • SD card security features can be utilized for boot medium verification or booting of locked SD cards.

Linux 2.6 and Debian Linux

Technologic Systems TS-7390 ARM Single Board Computer (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 ships with Linux 2.6 Kernel running out-of-the-box. They are the first Technologic Systems EP9302 ARM9 computers which use 2.6 Kernel by default. Linux Kernel includes complete driver support for on-board hardware, enabling quick time to market of end-users applications. Examples and source codes are also available for downloading.

The TS-7390 SBCs are configured to load the Debian Linux OS from either the on-board flash or a SD Card during boot up time. The full featured Debian Linux (version Sarge) distribution includes a complete GNU C/C++ embedded development environment installed. In addition, Apache Web Server, FTP, SSH, Telnet and Samba network services are available with C/PHP/Perl for embedded CGI development.

Eclipse IDE for TS-7000 and Windows

The Eclipse IDE configured for embedded development with the TS-7000 ARM9 computers running Debian Linux is provided along with the 2GB development SD Card. Technologic Systems makes use of the Eclipse Europa release and the DSDP+CDT plugins in order to provide an advanced IDE and makes embedded development easier. ARM crosstool chains, cygwin runtime-libraries and a Java Development Kit are installed on the card, therefore Eclipse IDE will run out-of-the-box (no need for installation) on your Windows PC. The Eclipse environment is already configured to allow a quick startup with a TS-7000 embedded development. After start-up, the installed 'helloworld' example shows the user how to use the Eclipse functionalities, including cross-compilation, build-management configurations, binary download to the TS-7000 target, target management via SSH, FTP, telnet or serial console, client-server debugging with Eclipse debug view, etc.

Please contact Technologic Systems for further information regarding Operating System and software support for this product.
