Release Information

Latest Ver.: V.2.07 Release 00

Released: Feb 22, 2018

Details of upgrade (See Tool News)


  • Memory-saving compact design (TCP/IP protocols processable by the internal memory of the microcontroller)
  • OS's unnecessary
  • Compliant with ITRON TCP/IP API specification
  • We have prepared a wrapper which converts the specifications of the ITRON TCP/IP API into those of a socket API.
  • Sample driver for LAN controller available
  • Efficient development through a combined use of Renesas development tools supported
  • We provide a range of the Sample Code for T4 as an Application Note.


  • TCP/IP protocol stack software (library in binary form)
  • Various sample driver software*
  • TCP/IP protocol stack sample program
  • TCP/IP protocol stack manual and other documents in a complete set

* The sample drivers are verified their running on the evaluation boards placed in the Operating Environment.
