Safety System Basis Chip with Low Power Fit for ASIL D
FS26 Receive alerts
FS26 silicon and enablement (documentation, software and boards) are available for select customers with an approved NDA. For additional information and sample availability, contact support or your local sales representative.
The FS26 family of automotive safety system basis chip (SBC) devices offer multiple power supply options designed to support entry and mid-range safety microcontrollers like the S32K3 series. FS26 devices also enable other microcontrollers targeting automotive electrification such as powertrain, chassis, safety and low-end gateway applications.
The FS26 features multiple switch mode regulators as well as LDO voltage regulators to supply the microcontroller, sensors, peripheral ICs and communication interface. FS26 offers a high-precision voltage reference available to the system and a reference voltage for 2 independent voltage-tracking regulators. In addition, various functionalities are available for system control and diagnostics such as analog multiplexer, GPIOS and selectable wake up events from I/O, long duration timer or SPI communication.
The FS26 is ISO 26262 compliant, covering ASIL B and ASIL D safety integrity levels. It features multiple fail-safe outputs, becoming a full part of a safety-oriented system partitioning, along with the latest on-demand latent fault monitoring.
