The ENC424J600 and ENC624J600 are stand-al
one, Fast Ethernet controllers with an industry standard Serial Peripheral Interface (SPI) or a flexible parallel interface. They are designed to serve as an Ethernet network interface for any microcontroller equipped with SPI or a standard parallel port.
ENC424J600/624J600 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. They incorporate a number of packet filtering schemes to limit incoming packets. They also provide an internal, 16-bit wide
DMAfor fast data throughput and support for hardware IP checksum calculations.
For applications that require the security and authentication features of SSL, TLS and other protocols related to cryptography, a block of security engines is provided.
The engines perform RSA, Diffie-Hellman, AES, MD5 and SHA-1 algorithm computations, allowing reduced code size, faster connection establishment and throughput, and reduced firmware development effort.
Communication with the microcontroller is implemented via the SPI or parallel interface, with data rates ranging from 14 Mbit/s (SPI) to 160 Mbit/s (demultiplexed, 16-bit parallel interface). Dedicated
pins are used for LED link and activity indication and for transmit/receive/DMA interrupts.
