Examples of customization

Example 1: Example of base replacement


Since many parts of old models have been discontinued and it is difficult to continue settlement of payments, it is necessary to change the parts and continue production.

  • Discontinued production of CPU
  • Discontinued production of controller ICs such as PCI, PanelLink, HDLC, DDS, etc.
  • End of OS support
Development Content
  • Adopt the latest CPU
  • Use FPGA to realize functions such as PCI, PanelLink, HDLC, DDS, etc.
  • Change the OS
  • Enables continuous production while retaining existing functions
  • Achieves high-speed processing and space saving by adopting the latest parts
  • Functions can be added by saving space

Example 2: Example of carrier board creation


Develop a carrier board that has Com-Express as a core and possesses the required I/F

Development Content

Develop terminals and devices with the following specifications
(Main Specifications)

  • SATA
  • LVDS, eDP
  • Touch panel
  • PCI-Express
  • LAN, Wi-Fi
  • USB
  • Support for Microsoft Windows 10 IoT Enterprise
  • Adopting Com-Express for the core circuit significantly shortens the period until mass production.
  • Flexibly supports the I/F required by customers.
  • Even if the CPU is discontinued, continuous production is possible by replacing the module.

Example 3: Product development case for industrial buses

Requirements for developed equipment

We have developed CPU boards and slave boards equipped with the industrial buses requested by our customers.

Industrial bus with track record
  • EtherCAT
  • DeviceNet
  • CC-Link
  • PowerLink
  • *Various industrial buses can be used upon request.
