Germany-based chipmaker Infineon Technologies has completed the purchase of Marvell Technology’s Automotive Ethernet business for a total of $2.5bn in cash.
The deal, initially announced in April this year, has now cleared all regulatory hurdles.
This strategic move bolsters Infineon’s capabilities in the burgeoning market for software-defined vehicles (SDVs) and enhances its standing in the automotive microcontroller sphere.
According to Infineon, ethernet technology is instrumental in facilitating swift and efficient data transfer among various vehicle components. It is particularly critical for the functionality of SDVs.
By integrating Marvell’s Automotive Ethernet offerings, which include PHY transceivers, bridges, and switches, Infineon aims to deliver a robust suite of solutions to its clientele.
These products are essential for the underlying communication systems in SDVs, offering networking capabilities that range from 100Mbps to 10Gbps, along with the requisite security and safety features.
