TJA1080 FlexRay
Bus Driver
High-speed time-triggered
communication system
transceiver chip
As Philips’ first silicon solution for the FlexRay electrical
physical layer, the TJA1080 high-speed time-triggered
communication system transceiver chip highlights FlexRay’s
power and versatility. Offering an extensive feature set,
excellent EMC performance and unique possibility to be used
also in active star couplers the TJA1080 is helping drive this
new advanced communications system into tomorrow’s cars.
Semiconductors
Philips’ high-speed time-triggered communication system transceiver chip
offers an extensive feature set, excellent EMC performance and unique
potential for use in active star couplers. Combining FlexRay transceiver
and FlexRay active star device on a single chip, the TJA1080 supports the
full bandwidth of FlexRay, from 500 kbit/s to 10 Mbit/s. Internal voltage
and temperature monitoring, bus error detection and a safety time-out
make the TJA1080 a cornerstone of any FlexRay ECU.
Key features
• Data transfer up to 10 Mbits/s
• Compliant with FlexRay electrical physical layer specification
• Fail-silent behavior via Bus Guardian control input
• Interface to optional Bus Guardian available for bus access supervision
• Excellent EMC performance (due to 3rd generation
Silicon-On-Insulator process)
• High common mode range ensures excellent EMI
• 12, 24 and 42 V system support with low sleep current (maximum 50 µA)
• Supports 2.5, 3.0, 3.3 and 5 V microcontrollers and automatically adapts
to interface levels
• Integrated automotive power management system
- two INH-pins enabling power consumption optimized ECU design
- local wake-up input
- remote wake-up capability via FlexRay bus in low power modes
- autonomous power modes, when used in active stars
• ± 8 kV ESD protection (HBM) on BP and BM pins
• Automotive temperature range –40 °C to +125 °C
• Small footprint SSOP20 package (5.4 mm x 7.4 mm body)
Dedicated error and status information – readable by any microcontroller
– allows precise monitoring of system performance. In active star and
node configurations, features such as Sleep and Standby modes serve
the need for automotive power management. A Bus Guardian interface
rounds out the feature list and enables the TJA1080 to be used in systems
that require additional supervisions.
Key benefits
• Supports wide range of microcontrollers, maximizing flexibility and
lowering cost of nodes
• Enables autonomous active star couplers without a microcontroller
• Identical mode control as for TJA1041(A) and TJA1054(A) CAN
transceivers
• Simplifies development of robust and fully fail-silent communication nodes
