DeepSleep / Standby Modes

raratex — Thu, 17 Aug 2017 10:38:46 GMT

Hello Community,

I am actually optimizing/extending capabilities of one of our design and looking for any detailed information regarding different power-modes. Where can I find any information about different deep sleep and standby modes for QorIQ/Layerscape ARM processors (especially LS1 Family / LS1043A, LS1046A, LS1088A)?

What all the power conditions have to be fulfilled (power-sequencing, slew-rate, switching, ...) for the different power modes supported by ARM platform?

Best Regards,

Radek

Look at the Chapter 13 of the LS1043a Reference Manual and Section 3.5 of the LS1043a Datasheet. These documents are available on the following page:

http://www.nxp.com/products/microcontrollers-and-processors/arm-processors/qoriq-layerscape-arm-processors/qoriq-layerscape-1043a-and-1023a-multicore-communications-processors:LS1043A?tab=Documentation_Tab

See the following page about the LS1046a:

http://www.nxp.com/products/microcontrollers-and-processors/arm-processors/qoriq-layerscape-arm-processors/qoriq-layerscape-1046a-and-1026a-multicore-communications-processors:LS1046A?tab=Documentation_Tab

Have a great day,

Sorry, one question to LS1088A. In Reference Manual Rev. D 06/2017, page 1744 is some info missing:

Please, can you tell me, what is missing there?
