System Basis Chip, DCDC 0.8A Vcore CAN, LQFP48EP

The FS65 family of automotive system basis chips (SBCs) provides power management, communication interfaces, system control, and functional safety features for automotive electronic control units (ECUs).

The FS65 integrates DC-DC switching regulators, linear regulators, CAN FD and LIN transceivers, and ultra-low-power modes to optimize energy consumption. Developed for ISO 26262 applications up to ASIL B and ASIL D, the FS65 includes voltage monitoring, fail-safe mechanisms, watchdog functionality, and diagnostic features to support safety-oriented system architectures.

The device supports SPI communication for control and diagnostics and is qualified for operation up to 150 °C ambient temperature in AEC-Q100 Grade 0 applications.
