Microchip Technology is rolling out the LAN878x and LAN888x families of SPE PHY transceivers, just as automotive and industrial designers increasingly turn to SPE and all-Ethernet setups for Software-Defined Vehicles (SDVs) and complex networks.
Available in 100BASE-T1, 1000BASE-T1, and dual-speed 100/1000BASE-T1 versions, the new SPE PHY transceivers deliver secure, reliable, and scalable Ethernet connectivity for automotive and other critical applications.
What sets the LAN878x and LAN888x apart is their built-in MACsec security, compliant with IEEE 802.1AE-2018. It handles frame-level encryption, data integrity, and replay protection right in hardware no extra latency or software headaches.
They also pack native Time-Sensitive Networking (TSN) for the deterministic, low-latency performance needed in ADAS, zonal gateways, and safety-critical controls.
These families go further with enhanced functional safety, targeting ISO 26262 ASIL-B systems. On-chip diagnostics and link monitoring give better visibility, speed up fault detection, and bolster overall system safety compared to typical SPE PHYs.
Designers get real flexibility too: pin-compatible options across 100BASE-T1 and 1000BASE-T1 speeds, plus SGMII and RGMII host interfaces, mean you can reuse hardware while scaling bandwidth as needs evolve.
The LAN878x lineup includes the LAN8781, LAN8781M, LAN8782, and LAN8782M. The LAN888x adds LAN8881, LAN8881M, LAN8882, LAN8882M, LAN8883, LAN8883M, LAN8884, and LAN8884M—”M” models include MACsec. All are built tough, with max junction temps up to 150°C and Automotive Grade 1 operation from -40°C to +125°C.
Beyond cars, the new SPE PHY transceivers are said to be a great fit for industrial automation, robotics, avionics, and any system needing precise Ethernet timing.
Development Tools
The LAN878x and LAN888x PHY transceivers are supported by comprehensive hardware evaluation platforms; SGMII, USB and PCIe® plug-in boards and Linux® software drivers.
Leadership Comment
“OEMs need a clear and efficient path to scale Ethernet performance as vehicle networks evolve,” said Charlie Forni, corporate vice president of Microchip’s networking and connectivity business unit. “The LAN878x and LAN888x families allow teams to reuse designs while supporting higher data rates and stronger security. By integrating MACsec directly in the PHY, we help designers enhance network protection without added system complexities.”
Pricing and Availability
The LAN878x and LAN888x families are available in limited sampling. To learn more, please contact a Microchip sales representative.
