AUTOMOTIVE ELECTRONICS

Integrated solution for smart chip for Ethernet inter-operability
in infotainment systems,” said Matthias
Kaestner, vice president, Automotive. “In
today’s rapid pace design environment,
vehicle Ethernet audio this out-of-the-box device gives
engineers a quick start to development
and allows them to avoid months of
engineering work and technical risks
video bridging involved in coding or engaging third
party integrators.”
Other Microchip Ethernet devices
for automotive applications include the
LAN8770 100BASE-T1 PHY, a cost-
effective, single-port physical layer
transceiver compliant with the IEEE
802.3bw-2015 specification. The device
provides 100 Mbps transmit and receive
capability over a single Unshielded
Twisted Pair (UTP) cable. In addition,
the Trust Anchor (TA100), a secure
element from Microchip’s portfolio of
Crypto Automotive security ICs for
automotive security applications,
provides support for code
authentication, secure boot and audio
content protection with High-bandwidth
Digital Content Protection (HDCP).
