7.6.5 System Topologies

The following the system topologies are supported.

  • Topology 1: Autonomous mode, with ability to wake-up external MCU
  • Topology 2: Peripheral mode, under control of external MCU
IWRL6432AOP System Topologies Figure 7-1 System Topologies

In Topology 1: Autonomous mode, the IWRL6432AOP can be used as full sensor along with M4F application processor. In this case the internal application processor does all the processing and interrupts the host processor to communicate to take action based on the sensor data. Most of the processing happens on the internal MCU of the IWRL6432AOP chip and only high level desired results are communicated to external host via LIN/CAN.

In Topology 2: Peripheral mode, the IWRL6432AOP is controlled by external MCU and most of the processing is done on external MCU. In this case computational and power requirements are higher and the external MCU stays active most of the time.
