LAN88730

The LAN88730 is a high-performance, low-power 10/100 Ethernet controller which incorporates the essential protocol requirements for operating an IEEE 802.3 10BASE-T and 802.3u 100BASE-TX compliant Ethernet node. It is specifically designed to meet the high reliability standards required by automotive applications, including on-board diagnostics and fast software download interfaces for central gateway and telematics modules, navigation systems, radio head units and connectivity devices. The LAN88730 offers increased access speed for diagnostics and software downloads when compared with the more traditional, slower speed interfaces that are typically used.

The LAN88730 provides a simple, digital interface via MII (IEEE 802.3u) to a standard MAC layer integrated in an embedded microcontroller. When built into an embedded device within the car, the chip can function as a network branch to the outside world, connecting the car to a personal computer, diagnostic tool or a complex Ethernet network in the repair shop.

The LAN88730 can be configured for either 10 or 100 Mbps Ethernet operation in full and half-duplex mode. To determine the best possible speed and duplex mode of operation, it automatically implements Auto-Negotiation.

HP Auto-MDIX is also supported and provides detection and correction of both direct connection and crossed Ethernet cabling.
