FS4500: Grade 1 and Grade 0 Safety Power System Basis Chip with CAN Flexible Data Transceiver

Overview

The NXP^® FS4500 system basis chip (SBC) provides power to MCUs and optimizes energy consumption through a DC/DC pre-regulator and linear regulators and ultra-low-power saving modes. Featuring:

Advanced functional safety measures to target ASIL B or D applications
A serial peripheral interface (SPI) to allow control and diagnostics with the MCU
Integration of CAN FD and LIN physical interfaces compliant with the ISO 11898-2,-5, LIN 2.2, 2.1 /J2602-2 standards along with the latest automotive OEM standards for EMC and ESD
A range of integrated safety features such as monitoring of critical analog parameters, a fail-safe state machine and an advanced watchdog reduce software complexity with dual-core lock-step MCUs
High-temperature capability up to TA = 150 ^°C and TJ = 175 ^°C, compliant with AECQ100 Grade 0 automotive qualification
