: Features integrated 802.1AE MACsec with 128/256-bit AES encryption to secure vehicle data communication against tampering or eavesdropping [5.6, 5.16].

The PHY supports the OPEN Alliance TC10 standard for selective wake/sleep. In a zonal architecture, an ADAS domain controller can be fully asleep while a lighting zone controller remains active—all without special switch logic. The BCM89890 listens for wake patterns while drawing microamps. bcm89890
