Evaluation Kit - 33905D3, System Basis Chip GEN2 With High Speed CAN And LIN Interface

This evaluation board allows the user to implement the functionality of the 33905BD3 and 33904B3 System Basis Chips (SBC), which are the second generation family of System Basis Chips, which combine several features and enhance present module designs. The devices work as an advanced power management unit for the MCU and additional integrated circuits such as sensors, CAN transceivers. They have 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 SBCs may include one or two LIN 2.0 interfaces with LIN output pin switches. The 33904/5 include 2 or 3 wake-up input pins than can also be configured as output drivers for flexibility. This Evaluation kit may be used with the KITUSBSPIDGLEVME.
