MC33908 Device Features
The MC33908 is a multi-output IC, with power supply and HSCAN transceiver. This device is designed
specifically with the automotive market in mind. It supports the following functions:
•
Highly flexible SMPS pre-regulator, allowing two topologies: non-inverting buck-boost or standard buck
•
Switching mode power supply (SMPS) dedicated to MCU core supply: 1.2 V or 3.3 V, delivering up to 1.5 A
•
Linear voltage regulator dedicated to MCU A/D reference voltage or I/Os supply (V
CCA
): 5.0 V or 3.3 V
•
Linear voltage regulator dedicated to auxiliary functions or to a sensor supply (V
CCA
tracker or independent
5.0 V/3.3 V)
•
Multiple wake-up sources in low-power mode: CAN and/or IOs
•
Battery voltage sensing and multiplexer output terminal (various signal monitoring)
•
Enhanced safety block associated with fail-safe outputs
•
Six configurable I/Os
•
ISO11898 high-speed CAN interface compatibility for baud rates of 40 kB/s to 1.0 MB/s
•
High EMC immunity & ESD robustness

Important notice:
The mother board (KIT33908MBEVBE) is extensible by the daughter board (KITMPC5643DBEVM) and cannot
operate separately. The equipment list is considered for operation with the KITMPC5643DBEVM uniquely. Two
modes of operation with this platform can be distinguished:
Recommended equipment for software development:
•
Power supply 12 V/3.0 A
•
USB A-B cable
•
P&E USB Multi-link Debugger
•
USB-enabled PC
Recommended equipment for hardware development (validation of analog functionality etc.):
•
Power supply: typically 12 V/3.0 A
•
USB A-B cable
•
USB-enabled PC
Recommended software:
•
Windows 7 32-bit operating system
•
