2.4 Device features
The FS65xx/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.

2.5 Board overview
The primary components of the evaluation boards are the onboard MCUs. The boards include an FS45xx or FS65xx and provide full
access to all the device’s features. An MKL25Z MCU USB controller enables access to the FS45xx/FS65xx through a USB connection.
In normal operation, configuration and monitoring applies to the on-board FS45xx/FS65xx device. However, the board can be totally
isolated from the on-board MCU. This allows connection to an off-board MCU without interference from the on-board device functions.
