What the ENC28J60 does
The ENC28J60 is a standalone Ethernet controller featuring an integrated MAC and 10Base-T PHY. It operates on a 3.1V to 3.6V supply with a 25MHz clock input and supports 10/100Base-T networks. The device includes an 8-Kbyte dual-port SRAM buffer and an SPI interface running up to 20MHz. It handles full and half-duplex modes with programmable receive filtering and hardware-assisted checksum calculation. Available in 28-pin SPDIP, SSOP, SOIC, and QFN packages, it functions across commercial and industrial temperature ranges. This component is typically used in embedded systems requiring a compact, low-power Ethernet connection with automatic collision retransmission and polarity detection.
