Ultracompact TCP/IP protocol stack (high-speed version) [M3S-T4-Tiny]
Network software library - Ultracompact TCP/IP protocol stack [high-speed version]
Overview
M3S-T4-Tiny (hereafter abbreviated "T4") is the communication protocol software library for Renesas microcntrollers. It makes TCP/IP communication possible in an Ethernet-connected network for all types of equipment that incorporates Renesas microcntrollers. It has been developed based on the advanced version of TCP/IP protocol stack, or M3S-T3-Tiny (hereafter abbreviated "T3"), by altering its specifications to enable the Ethernet interrupt. Furthermore, since T4 can process TCP/IP at high speed, it helps to reduce functional implementations to a possible minimum, thereby enabling the user to realize a compact program size.
This product supplies the basic TCP/IP functions that are needed when building network environments. (See the conceptual image shown below.)

Use of T4 enables network functions to be embodied in every system that incorporates the Renesas microcontroller easily with low cost.
High-quality, network-support embedded equipment such as Internet cameras, remote supervise/control systems and networking consumer electronics now find ever growing demands. Renesas microcontrollers, Renesas middleware and Renesas development tools (e.g., compilers, realtime OS and debuggers) used in combination help to realize prompt development and cost reduction for these pieces of equipment.
Furthermore, evaluation boards also are available that will help you start using T4 immediately. For details, please refer to Condtions of Use.
