The ENC624J600-I/PT is a stand-alone 10/100 Base-T Ethernet Interface Controller with integrated MAC and PHY, hardware cryptographic security engines and factory pre-programmed unique MAC address. A 24kB on-chip RAM buffer is for TX and RX operations. The ENC624J600 have an industry standard serial peripheral interface (SPI) or a flexible parallel interface. It is designed to serve as an Ethernet network interface for any microcontroller equipped with SPI or a standard parallel port. The ENC624J600 devices meet all of the IEEE 802.3 specifications applicable to 10Base-T and 100Base-TX Ethernet, including many optional clauses, such as auto-negotiation. It incorporates a number of packet filtering schemes to limit incoming packets.
