Microchip said the Ethernet controllers combine a 10/100Base-TX physical interface (PHY) and a Media Access Controller (MAC) with a hardware cryptographic security engine, and can connect to any PIC microcontroller via an industry-standard Serial Peripheral Interface (SPI) or a flexible parallel interface.
Additional abilities, accessible through a built-in serial peripheral interface (SPI), include: output on/off control; configurable over-current detection levels and blanking times for fuse emulation; selectable output slew rate control; device input status feedback; specific fault information and device status reporting; daisy chain capabilities; and a configurable turn-on delay for load demand optimization.
