FS25 System Basis Chip (SBC) for Automotive Zonal Architectures
- This page contains information on a preproduction product. Specifications and information herein are subject to change without notice. For additional information please contact your sales representative.
The FS25 system basis chip (SBC) is designed to support NXP's S32K5 and S32J devices by managing power distribution and system control. It addresses current energy management requirements and includes features for protection, fault handling and predictable operation.
Startup parameters are stored in one-time programmable (OTP) memory, reducing the need for external configuration components. The chip also includes an analog-to-digital converter (ADC), general-purpose inputs/outputs (GPIOs), and supports wake-up sources like input/output (I/O) events, long-duration timers and nter-integrated circuit (I²C) communication.
Developed in line with the ISO 26262, the FS25 supports ASIL D safety levels through an independent safety monitoring unit (iSMU) with built-in self-test and fail-safe outputs to meet the highest automotive safety integrity levels.
