AMIS-42675 High-Speed Low Power CAN Transceiver
For Long Networks
Data Sheet
1.0 General Description
The AMIS-42675 CAN transceiver is the interface between a controller area network (CAN) protocol controller and the physical bus. It
may be used in both 12V and 24V systems. The transceiver provides differential transmit capability to the bus and differential receive
capability to the CAN controller.
The AMIS-42675 is the low power member of the CAN high-speed transceiver family and offers the following additional features:
• Ideal passive behaviour when supply voltage is removed
• Wake-up over bus
• Extremely low current standby mode
Due to the wide common-mode voltage range of the receiver inputs, the AMIS-42675 is able to reach outstanding levels of electro-
magnetic susceptibility (EMS). Similarly, extremely low electromagnetic emission (EME) is achieved by the excellent matching of the
output signals.
The AMIS-42675 is the industrial version of the AMIS-42665 and primarily for applications where long network lengths are mandatory.
Examples are elevators, in-building networks, process control and trains. To cope with the long bus delay the communication speed
needs to be low. AMIS-42675 allows low transmit data rates down 10 Kbit/s or lower.
2.0 Key Features
• Compatible with the ISO 11898 standard (ISO 11898-2, ISO 11898-5 and SAE J2284)
• Wide range of bus communication speed (0 up to 1 Mbit/s)
• Ideally suited for 12V and 24V industrial and automotive applications
• Allows low transmit data rate in networks exceeding 1 km
• Extremely low current standby mode with wake-up via the bus
• Low electromagnetic emission (EME): common-mode choke is no longer required
• Differential receiver with wide common-mode range (+/- 35V) for high EMS
• Voltage source via V_SPLIT pin for stabilizing the recessive bus level (further EMC improvement)
• No disturbance of the bus lines with an un-powered node
• Thermal protection
• Bus pins protected against transients
• Power down mode in which the transmitter is disabled
• Bus and V_SPLIT pins short circuit proof to supply voltage and ground
• Logic level inputs compatible with 3.3V devices
• At least 110 nodes can be connected to the same bus
