S1S60000

S1S60000 is an intelligent network controller for the built-in equipment with built-in protocol processing function.

The TCP/IP communication can be done only by passing an easy command and data from host CPU to process necessary protocol processing for TCP/IP connection internally.

The equipment for the network such as 10Base-T can be easily achieved by combining the interface with a physical layer with the PHY chip for MII.

CPU machine used of 8/16 bit class is the best for doing the network connection correspondence without the necessity of the protocol stack that high performance OS and the software vender offer.

Moreover, various hosts CPU can connect it directly without additional logic.
It is possible to use it easily even with the equipment without, a general-purpose bus such as PCI and ISA, and an external bus.

Main specifications

  • The protocol processing to OSI model L4 layer internal is processed, and the network connection is achieved by an easy command operation.
  • Because the protocol stack of original development is used, the license cost is unnecessary.
  • General purpose I/O pin and the I2C bus can control easy hardware without host CPU from the network.
  • The RS232 ⇔ Ethernet conversion function is achieved alone.
  • The correspondence protocol can be added, and be changed by rewriting the Flash memory.
