Microchip Technology ENC424J600 / ENC624J600 Ethernet controllers enable designers to create secured network- and Internet-connected embedded applications with minimized board space, cost, and complexity. The Microchip ENC424J600 and ENC624J600 come equipped with integrated MAC & PHY, hardware cryptographic security engines, and a factory pre-programmed unique MAC address. These Microchip Technology Ethernet controllers have an industry standard SPI or a flexible parallel interface and are designed to serve as an Ethernet network interface for any MCU equipped with SPI or a standard parallel port. The Microchip Technology ENC28J60 Ethernet controller comes with an industry standard SPI and is designed to serve as an Ethernet network interface for any controller equipped with SPI.
