LAN9220-ABZJ

The LAN9220-ABZJ is a 16-bit Non-PCI small form factor 10/100 Ethernet Controller with variable voltage I/O and HP Auto-MDIX support. It is fully IEEE 802.3 10Base-T and 802.3u 100Base-TX compliant and supports HP Auto-MDIX. The variable voltage I/O signals of the LAN9220 accommodate lower voltage I/O signalling without the need for voltage level shifters. It includes an integrated Ethernet MAC and PHY with a high-performance SRAM-like slave interface. The simple, yet highly functional host bus interface provides a glue-less connection to most common 16-bit microprocessors and microcontrollers as well as 32-bit microprocessors with a 16-bit external bus. The integrated checksum offload engines enable the automatic generation of the 16-bit checksum for received and transmitted Ethernet frames, offloading the task from the CPU. It also includes large transmit and receive data FIFOs to accommodate high latency applications. It supports features which reduce or eliminate packet loss.
