AS8221

The AS8221 is a high-speed automotive bus driver designed according to the FlexRay Electrical Physical Layer Specification V2.1 Rev B. The AS8221 operates as a bi-directional interface between the FlexRay Communication Controller and the twisted-pair copper wiring.

Ensuring application of AS8221  in safety critical environments a two wire bus-guardian interface is implemented where additional monitoring circuitries on the electronic-control-unit can activate and deactivate the transmitter and additionally on the receive enable output in low power modes the wake conditions of AS8221 and in normal power modes the received FlexRay streams can be monitored.

AS8221 is available in RoHS conform SSOP20 package.
