AS8221  
High Performance Bus Transceiver  
PRODUCT BRIEF  
Applications  
General Description  
-
-
-
-
-
-
-
FlexRay™ networks  
The AS8221 is a high-speed automotive transceiver for  
fault tolerant and high speed applications, operating as  
High speed automotive bus systems  
Backbone bus and gateways  
Safety critical applications  
X-by-wire systems  
the bi-directional interface between  
a
generic  
communication controller and the twisted pair copper  
wires. The device enables two-way communications  
with the microcontroller with full mode handling,  
including the low-power modes.  
Redundant bus systems  
Bus topologies with active stars  
Package: lead-free SSOP20  
Key Features  
-
-
Data transfer up to 10 Mbps  
Functional Description  
Supports 2.5, 3, 3.3, 5 V microcontrollers and  
automatically adapts to interface levels  
Does not disturb the bus line when un-powered  
Fail silent behaviour  
Transmission rates up to 10 Mbps as well as the  
implemented Bus Guardian interface enables this  
transceiver the usage in fault tolerant and hard real-  
time applications in the stringent automotive  
environment.  
-
-
-
Protection against damage due to short circuit  
conditions on the bus (positive and negative  
battery voltage)  
An extended diagnostic interface, offers advanced bus-  
failure detection capabilities with the intelligent  
combination of bus-current measurement and logical  
comparators. A thermal sensor circuit with an integral  
shutdown mechanism prevents damage to the device in  
extreme temperature conditions. The symmetrical  
transient control for the high- and low-side driver for  
both the bus-minus and bus-plus line allows an ideal  
balance of communications over different network  
topologies, with excellent EMC performance.  
-
-
Supports 12, 24, 42 V systems with low sleep  
current (30 µA)  
Integrated power management system  
o
o
Two INH pins for the external voltage  
Local wake-up input via STBN-, WAKE- and  
TxD-Pins  
o
Remote wake-up capability via FlexRay™ bus  
in sleep mode  
-
-
Operating temperature range -40°C to +125°C  
Compliant with FlexRay™ Electrical Physical Layer  
specification  
-
-
Excellent EMC performance  
High common mode range insure  
excellent signal integrity on  
diverse bus topologies  
-
-
Bus guardian Interface for optional  
bus supervision  
Automatic  
protection  
thermal  
shutdown
