Analog, Mixed-Signal and Power Management MC34903/4/5 System basis chip with CAN high-speed and LIN interface Target Applications Overview • Industrial process control The 34903/4/5 is a member of the system basis chip (SBC) family. It combines several features and •Automation enhances present module designs. The device works as an advanced power management unit for • Motor control •Robotics the MCU with additional integrated circuits such as sensors and CAN transceivers. It has a built-in enhanced high-speed CAN interface (ISO 11898-2 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. This device is powered by SMARTMOS technology. This device implements multiple low-power (LP) modes, with very low-current consumption. In addition, the device is part of a family concept in which pin compatibility adds versatility to module design. The 34903/4/5 also implements an innovative and advanced fail-safe state machine and concept solution.
