netX 52 Chip Carrier incl. transformer - Real-Time Ethernet slave

Ready-to-solder netX design in stamp format
  • Complete slave interface in the smallest space

  • Integrated transformers are used to save a lot of space

  • Host connection via dual-port memory or SPI

  • One hardware for all Real-Time Ethernet systems

Real-Time Ethernet solution in the smallest space

The rapid and secure alternative to a slave interface developed by the customer is netRAPID. The compact, stamp-sized, 32 x 32 mm netX Chip Carrier is a solution that offers adequate costs per unit, a reduced risk, and a fast time-to-market. Like a standard QFP component, it will be soldered directly to the host system - by hand or SMD production process.

Optimized for minimum space requirements, netRAPID 52-RE contains all necessary operating components, such as Ethernet transformers, SQI Flash, and netX multi-protocol chip. Real-Time Ethernet communication is in focus. The protocol stack will be executed in the internal RAM of the netX. Thus, the hardware developer only needs to integrate network connectors, LEDs, and address switches on the host system. For the host system, a simple 2-layer printed circuit board is sufficient. The application development is reduced to the use of the API of the netRAPID.

To be able to profit from the full function of netRAPID, the licensed firmware must be acquired once and loaded during the manufacturing process.
