Description
For users of the TCP/IP protocol stack [M3S-T4-Tiny] for RX Family
Support for the TCP/IP protocol stack [M3S-T4-Tiny] for RX Family has been discontinued on December 19, 2025. In the future, please use the following successors.
Successor: lwIP FIT* modules (Download the following two modules: r_lwip_rx Driver FIT and r_lwip_driver_rx Driver FIT)

* FIT: Firmware Integration Technology
M3S-T4-Tiny for RX Family (hereafter abbreviated "T4") is a communications protocol software library for RX Family. It makes TCP/IP communication possible in an Ethernet-connected network for all types of equipment that incorporates RX MCUs.
Components
- 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.
Features
- 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.
