SJA1105 Low Power Standby or Sleep Modes?

Does the SJA1105 ethernet switch have any low power sleep or standby or shutdown modes?

If so, how do you enter that and how much power should I expect the device to draw?

If not, how much power does it draw on each rail assuming all interfaces are inactive and as many clocks as possible are stopped? Would it be ok to hold the SJA in reset or stop the main clock to save power?

Thanks,

Steve

Hi Steve,

the SJA1105 has no low power modes. You can disable the interfaces, which saves some power, but the core supply remains with some mA. Reset or power off would be possible to reach a low current consumption, but this requires a new configuration after Startup.

Best regards,

Steffen
