Fusion TCP/IPv4 Basic Stack for Nexperia

Overview:

The Fusion TCP/IP Software Stack, from Unicoi Systems, supports these Nexperia Processors from NXP Semiconductors: PNX1500 (including PNX0190 and PNX9520), and PNX1700 processor families. The stack is available in two versions: a Binary Linkable-Library version available at a relatively low-cost, and a Full Source Code version. Fusion works with NXP's NDK development software (the NDK must be purchased separately). Wireless networking is fully supported by the Atheros WiFi drivers for the NDK.

The Fusion TCP/IP Stack protocol suite provides developers a highly portable, embedded stack designed specifically for embedded applications. With its 20-year history, the Fusion Embedded TCP/IP Stack is the most widely used network protocol stack in the world with thousands of design wins and millions of Fusion Network-enabled products shipping. The Source Code version of the basic Fusion embedded TCP/IP stack includes source code for TCP, UDP, IP, ICMP, ARP, RARP, TFTP, BOOTP and IGMPv2. Optional security may be added to Fusion TCP/IP with IPsec.

License:

The Fusion stack is licensed on a customer's Product basis. In other words, if you use the stack in only one of your company's products, using only one type of Nexperia processor (PNX1500 or PNX1700 family), then you only pay for one Fusion license.

For example, if you use Fusion in two of your company's products, even if they are the same except that one uses the PNX150x and the other uses the PNX170x, then they are different products from the Fusion License point of view, and you need to purchase two Fusion licenses.

For a given Fusion license, for a given customer's product, multiple people at multiple sites can use the license, as long as all the work is only for the same customer product.
