Technical data sheet for the Microchip ENC28J60 SPI‑interface Ethernet controller, covering features, pinout, electrical specs and usage.
The ENC28J60 is a standalone Ethernet controller with an SPI interface that complies with IEEE 802.3. It integrates a MAC, 10 BASE‑T PHY, an 8 KB dual‑port SRAM buffer and hardware‑assisted IP checksum calculation. The device operates from a 3.3 V supply and can be used with a wide range of microcontrollers via its SPI bus.
The document provides detailed information on external connections, pin definitions, clock configuration, power‑down behavior, and electrical characteristics. It also includes package options (SPDIP, SSOP, SOIC, QFN) and guidelines for level‑shifting when interfacing with 5 V systems. This manual is written in Chinese.
