System Basis Chip Gen2 with High
Speed CAN and LIN Interface
which combine several features and enhance present module designs.
The device works as an advanced power management unit for the
MCU and additional integrated circuits such as sensors, CAN
transceivers. It has a built-in enhanced high speed CAN interface
(ISO11898-2 and -5), with local and bus failure diagnostics, protection,
and fail safe operation mode. The SBC may include one or two LIN 2.1
interfaces with LIN output pin switches. It includes up to 4 wake-up
input pins than can also be configured as output drivers for flexibility.
current consumption. In addition, the device is part of a family concept
where pin compatibility, among the various devices with and without
LIN interfaces, add versatility to module design.
state machine and concept solution.
Features
• Protected 5.0V or 3.3V regulators for MCU (part number selectable)
• Fully-protected embedded 5.0 V regulator for the CAN driver
• Extremely low quiescent current in low power modes
• Multiple under-voltage detections to address various MCU
• Multiple wake-up sources in low power modes: CAN or LIN bus, I/O
• Voltage, current and temperature protection with enhanced
• ISO11898-5 high speed CAN interface compatibility for baud rates
• Pb-free packaging designated by suffix code EK
