Technologic Systems releases the TS-7500 250MHz Compact Computer - Our Smallest Computer at Our Best Price Point

Published as a News Article on Jul 6, 2009 (Updated Feb 11, 2022)

Technologic Systems announces the release of the TS-7500 250MHz Arm9™-based embedded computer for July/2009. The TS-7500 is our smallest computer at our best price point. It is a full-featured Linux embedded development platform that provides high-end features, such as high-speed USB2.0 and a customizable FPGA, and targets compact, low-cost and low-power embedded applications.


The TS-7500 is a ultra-compact embedded computer module based on a 250MHz Arm9™-based CPU from Cavium Networks. In comparison to the TS-7400, it is less expensive, about half the size and over 50% faster. The TS-7500 offers additional features such as High-Speed USB host and device, micro-SD Card socket and 5K LUT customizable on-board FPGA. The 44-pin header allows an external board to interface with the TS-7500 via DIO lines, SPI, I2C or FPGA cores.

With 64MB RAM, a bootable 4MB on-board flash, and a micro SD card slot, the TS-7500 is a powerful and flexible embedded solution. External devices can connect to the TS-7500 via Ethernet, USB host, USB device, or I2C ports as well as DIO, UARTs, and SPI which are implemented in the standard FPGA load. The 44 pin downward-facing, general-purpose header makes it easy to interface the TS-7500 with a base board of your own design. Using just under 400mA at 5V, a TS-7500 driven product can be fully powered by a USB device cable.

Features include:

  • 250MHz Arm9™-based CPU
  • 64 MB DDR-RAM
  • 4 MB NOR Flash
  • 5K LUT customizable FPGA
  • 1 micro SDHC Card slot
  • USB2 480Mbit/s Host(2) / Device(1)
  • 1 10/100 Ethernet
  • 8 TTL UART
  • 33 DIO, SPI and I2C interfaces
  • Watchdog Timer
  • Optional BB-RTC, CAN bus, WiFi
  • Power-over-Ethernet Ready
  • Small size (67mm x 75mm)
  • Low power (400mA @ 5V)
  • Fanless Operation from 0 C to 70 C
  • Unbrickable, boots from SD or Flash
  • Boots Linux 2.6 in less than 3 seconds


Does your application require custom real-time logic such as non-standard bus interfaces, PWM outputs, quadrature decoding, pulse timing, or digital counters? Technologic Systems can integrate that functionality into a custom TS-7500 FPGA configuration for an elegant and affordable solution. The standard TS-7500 FPGA configuration implements the following features: Micro SD card access, up to 8 UARTs, SPI Watchdog timer, up to 33 DIO lines, etc.


The TS-7500 development kit includes the TS-ENC750 enclosure with the TS-752 base board. The TS-752 base board demonstrates the power of the TS-7500, implementing Relays, RS-232, RS-485, power over Ethernet, and signal protection for DIO.

The TS-7500 ships with Linux 2.6 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 bootrom firmware loads kernel/initial ramdisk and boots to a shell prompt in in less than 3 seconds. The compact initial ramdisk filesystem is based on Busybox and uClibc and is improved for performance and flexibility.

The full featured Debian Linux (version Lenny-oabi) distribution is available on the development micro-SD Card and includes a complete GNU C/C++ embedded development environment installed. The Apache Web Server, FTP, SSH, Telnet and other network services are also available with C/PHP for embedded CGI development. In addition, Eclipse IDE for Windows has been configured for out-of-the-box embedded development with the TS-7500 computer and is also included on the micro-SD Card.


The TS-7500 starts shipping in July 2009 priced at $139 for qty 1, $99 for qty 10 and $84 for qty 100. The TS-7500 development kit is priced at $200 and includes a TS-ENC750 enclosure with TS-752 base-board, 2GB development SD Card with Eclipse IDE, power-supply and extras.
