com 1 General Description This document is subjected to change without notice.
The AS8221 is a high speed automotive bus driver fully conforming 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.
The AS8221 provides an optimized host controller interface consisting of three low-active pins.
The Enable (EN) and Standby (STBN) input pins for mode handling by the microcontroller and the Error (ERRN) out pin where system, chip failures or status information are signalled to the microcontroller.
Signalling logic high on the Enable and Standby pin the device will enter NORMAL mode in case no fault condition is given and in this mode the device is fully operational meaning FlexRay communication is possible.
Additionally a RECEIVE-0NLY mode is implemented, which c...
