Freescale Semiconductor Technical Data Document Number: MC34903_4_5 Rev. 4.0, 10/2013 System Basis Chip with CAN High Speed and LIN Interface I3n34d49u90s03t3/r4/i/a5l The 34903/4/5 is the second generation family of the System Basis Chip (SBC). It combines several features and enhances present module designs. The device works as an advanced power management unit for the MCU with additional integrated circuits such as sensors and 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 modes. The SBC may include zero or one LIN 2.1 interface with LIN output pin switches. It includes up to four wake-up input pins that can also be configured as output drivers for flexibility.
