This document contains device-specific information for
the following devices:
• ENC424J600
• ENC624J600
The ENC424J600 and ENC624J600 are stand-alone,
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
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
DMA for fast data throughput and support for hardware
IP checksum calculations.
For applications that require the security and authenti-
cation 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
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.
A generous 24-Kbyte on-chip RAM buffer is available
for TX and RX operations. It may also be used by the
host microcontroller for general purpose storage.
Communication protocols, such as TCP, can use this
memory for saving data which may need to be
retransmitted.
For
ENC624J600 family device is preprogrammed with a
unique nonvolatile MAC address. In most cases, this
allows the end device to avoid a serialized
programming step.
The
ENC424J600 (44-pin) and ENC624J600 (64-pin)
devices are the number of parallel interface options
they support. These differences, along with a summary
of their common features, are provided in Table 1-1. A
general block diagram for the devices is shown in
Figure 1-1.
A list of the pin features, sorted by function, is
presented in Table 1-2.
