Product Features
-
IEEE 802.3-compliant – on-chip 10 Mbps Ethernet Physical Layer Device (PHY) and Medium Access Controller (MAC), providing reliable packet-data transmission/reception based on an industry-standard Ethernet protocol.
-
Programmable filtering – special filters, including Microchip’s programmable pattern-matching filter, automatically evaluate, accept or reject Magic Packet®, Unicast, Multicast or Broadcast packet types, minimizing the host microcontroller’s processing requirements.
-
10 Mbps SPI serial interface – industry-standard serial communications port, allowing even 18-pin, 8-bit microcontrollers to be network enabled.
-
Programmable 8-Kbyte dual-port SRAM buffer – enables an efficient method for packet storage, retrieval and modification, eliminating memory requirements for the host microcontroller. This buffer memory provides a flexible, reliable datamanagement system.
