Function
5
TxEN
Transmitter Enable Not Input;
integrated “pull-up” current source to V_IO,
logical “low” to enable the Transmitter.
6
RxD
7
BGE
Receive Data Output;
logical “low” while “Data_0” is on the FlexRay bus,
output voltage adapted to the voltage on the V_IO level shift input.
Bus Guardian Enable Input;
logical “high” to enable the Transmitter,
integrated “pull-down” current source to GND.
8
STBN
Stand-by Not Mode Control Input;
digital input for the mode selection,
integrated “pull-down” current source to GND.
9
RxEN
10
ERRN
11
V_BAT
Receive Data Enable Not Output;
logical “low” indicates activity on the FlexRay bus,
logical “high” in case the FlexRay Bus is “Idle”,
output voltage adapted to the voltage on the V_IO level shift input.
Error Not Diagnosis Output;
logical “low” in failure case,
output voltage adapted to the voltage on the V_IO level shift input.
Battery Voltage Supply;
100 nF decoupling capacitor to GND recommended.
12
WAKE
Wake-up Input;
local wake-up input, terminated against GND and V_BAT,
wake-up input sensitive to signal changes in both directions.
13
GND
Ground;
14
BM
Bus Line Minus;
negative input/output to the FlexRay bus.
15
BP
Bus Line Plus;
positive input/output to the FlexRay bus.
16
V_CC
Supply Voltage;
Transmitter supply voltage,
100 nF decoupling capacitor to GND recommended.
