1. SPINET
SPINET is a module based on ENC28J60 Ethernet controller by
Microchip
providing easy connection of application circuitry to an Ethernet network
without necessity of previous knowledge of physical layer of this interface.
SPINET contains 10BASE-T physical layer (PHY) including RJ45 connector with
galvanic insulation and media access control logic (MAC). The module supports
half duplex and full duplex operation at 10 Mb/s and it is equipped by 8 kB of
dual port SRAM for incoming and outgoing data. Besides of other features it
includes hardware engine for copying blocks of memory and checksum
calculation in one's complement arithmetics (IP checksum) and CRC.
