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

FS4500

Roll over image to zoom in

The FS45 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 AEC-Q100 Grade 0 automotive qualification
