4.4 Device features
TheFS65xx/FS45xx are multi-output power-regulating SMARTMOS devices aimed at the
automotive market. They include CAN flexible data (FD) and/or LIN transceivers.
Multiple switching and linear voltage regulators—including low-power mode (32 μA) —
provide a variety of wake-up capabilities. An advanced power management scheme
maintains high efficiency over a wide range of input voltages (down to 2.7 V) and output
current ranges (up to 2.2 A).
The FS45xx/FS65xx family includes enhanced safety features with multiple fail-safe
outputs. The devices are capable of fully supporting safety-oriented system partitioning
with a high integrity safety level (up to ASIL D).
The built-in CAN FD (flexible data-rate) interface meets all ISO11898-2 and -5 standards.
The LIN interface is compliant with LIN protocol specifications 2.0, 2.1, 2.2, and
SAEJ2602-2.

4.5 Getting to know the hardware
The primary component of the evaluation boards is the SBC. The boards include an
FS45xx or FS65xx and provide full access to all the device’s features.
This EVB can either be used alone, or connected to the FRDM-KL25Z board included
with this EVM. This provides access to all the features and I/Os of FS45xx/FS65xx
through a USB connection.
