Analog, Mixed-Signal and Power Management MC33903/4/5 System Basis Chip Gen2 with High Speed CAN and LIN Interface Overview The MC33903/4/5 is the second generation family of System Basis Chips, 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 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 mode. The SBC may include one or two LIN 2.1/J2602-2 interfaces with LIN master terminal outputs. It includes wake-up input pins than can also be configured as output drivers for flexibility. This device implements multiple Low Power modes with very low-current consumption. In addition, the device is part of a family concept where pin compatibility, among the various devices with and without LIN interfaces, adds versatility to module design. The MC33903/4/5 also implements an innovative and advanced fail-safe state machine and concept solution. This family of devices are supported by an enablement ecosystem that includes an evaluation board, software interface, EMC/ESD conformance reports and training material that allows a faster time to market and eases your designs.
