TCP/IP Networking Components

Our network solution is a scalable, thread safe TCP/IP stack. It provides a familiar, standards based, Berkeley sockets interface, making it as simple to use and as quick to learn as possible. An alternative callback interface is also available for advanced users.

The features and RAM footprint are fully scalable, making our solution equally applicable to smaller, lower throughput microcontrollers as larger, higher throughput microprocessors. It is available with a light weight HTTPS web server, please ask one of our sales representatives for more details.

See the TCP/IP Users Manual to the right for full documentation and API reference guide.
