Computing And Software

Ethernet technology in automotive should see massive adoption in the coming years, with up to a half-billion Ethernet ports deployed in cars by 2020, according to Strategy Analytics. Starting with Europe, the standardization of one-pair Ethernet technology by OPEN and IEEE, based on Broadcom’s BroadR-Reach, has led to a strong increase with ~300 automotive and technology companies now involved.

The BCM89501 uses Broadcom’s high-performance BroadR-Reach Ethernet technology, the world’s first Ethernet automotive solution, to deliver 100Mbps over unshielded single-twisted pair cable. This technology for automotive central gateway, Advanced Driver Assistance (ADAS), and infotainment is on the road today in a wide range of vehicles, and according to Broadcom it reduces connectivity cost by up to 80% and cabling weight by as much as 30%.

The BCM89501 is a highly-integrated 7-port switch with five embedded PHYs. The component is provided in a thermally-enhanced eLQFP 176-pin package and delivers the most comprehensive automotive technology solution required by OEM and Tier 1 suppliers, with automotive grade-2 temperature, AEC-Q100, and TS16949 certifications.

Built with a 65nm technology, the circuit integrates an ARM Cortex R4 processor and a large amount of on-chip SRAM. This report, based on a complete physical analysis of the chip, provides an estimated manufacturing cost and selling price along with forecasts for the coming years.
