    Wakeup via CAN, Deep Sleep Mode

    heahc_3966201

      Hello, I am getting into using psoc 4100 cortex M0 line products. My clients requirements, regarding power consumption in idle state, allow me to just put the whole system in the lowest power possible(less or equal to deep sleep mode) when no task is at hand. Wake up process starts via either CAN wake up protocol or NFC.

      I have no worries about NFC, which has a IRQ pin to wake the processor. My concerns reside in CAN. Deep sleep closes the interrupt channel by which CAN communication is able to initiate wakeup process. My viable option is GPIO. However, its not easy to find a CAN transceiver which signals out that wake up protocol is received.

      Any suggestions? Thanks in advance.
