DESCRIPTION
S1S60000 is an intelligent network controller equipped with the built-in protocol processing function.
Simplified commands and data from the host CPU enables S1S60000 to establish TCP/IP communication thanks
to its capability of internally processing protocols for TCP/IP connection including ARP, ICMP, IP, TCP and UDP.
MII (Media Independent Interface) is employed for interfacing the physical layer.
Just adding PHY chip
designed for MII allows you to realize 10BASE-T/100BASE-TX equipment operable on networks.
S1S60000 is
best suited for making your 8/16 bits class CPU-featured equipment connectable to network without using a
HIGH performance OS or protocol stacks provided by software vendors.
Also, it enables to connect your equipment directly to various types of host CPUs without using additional logic
circuits.
There is no trouble in using it on equipment not provided with a general-purpose bus or external bus such as PCI
and ISA.
1.1
Features
Internally processes protocols for up to L4 layer of OSI model.
Realizes network connection with simple command operations.
Eliminates license costs thanks to the unique protocol stack.
General purpose I/O pins and I2C busses allow controlling hardware simply from network without using a
host CPU.
Realizes the function to convert RS232 into Ethernet and in reverse independently.
Allows adding or changing the protocols used through rewriting of the Flash ROM.

SIS60000 series (EPSON Network Controller for Embedded System) is the general name for the network
ICs equipped with the built-in protocol stack.
S1S60000 is the first product of SIS60000 series.
1 Can be used only for hardware control.
2 Can be used only for Flash ROM update from the network.
