CAN controller interface PCA82C250
FEATURES
• Fully compatible with the “ISO 11898” standard
• High speed (up to 1 Mbaud)
• Bus lines protected against transients in an automotive environment
• Slope control to reduce Radio Frequency Interference (RFI)
• Differential receiver with wide common-mode range for high immunity against ElectroMagnetic Interference (EMI)
• Thermally protected
• Short-circuit proof to battery and ground
• Low-current standby mode
• An unpowered node does not disturb the bus lines
• At least 110 nodes can be connected.
APPLICATIONS
• High-speed applications (up to 1 Mbaud) in cars.
GENERAL DESCRIPTION
The PCA82C250 is the interface between the CAN protocol controller and the physical bus. The device provides differential transmit capability to the bus and differential receive capability to the CAN controller.
