Car access Bluetooth® low energy + CAN satellite module reference design


Design files


This satellite module reference design is intended for Bluetooth® low energy passive entry passive start (PEPS) and phone as a key / digital key car access systems. The design demonstrates how control area network flexible data rate (CAN-FD) communication capabilities can be implemented with our Bluetooth wireless MCUs for systems that require higher bandwidth in-vehicle networking communications. Further benefits include reduced power consumption in the sleep state, our CAN auto-addressing method for improved manufacturing, connection monitor capabilities for improved Bluetooth localization accuracy and a compact printed-circuit board (PCB) capable of measuring Bluetooth angle of arrival (AoA) and received signal strength index (RSSI).

  • CAN and CAN-FD communications
  • CAN auto-addressing
  • Capable of measuring Bluetooth AoA and RSSI
  • Small 47.625-mm × 76.2-mm (1.875 in × 3 in) PCB
  • Improved system performance with Bluetooth connection monitoring capabilities
