Power Delivery Subsystem

All power sources for the Intel Joule expansion board are routed into a multiplexer device, U18.
The power mux defaults to +VDC_IN when both +VDC_IN and +VBUS are present. Refer to the manufacturer's datasheet for input impedance, current limit details, and low voltage lock-out specifications.
When it is booted, it is not possible to switch between power input sources without rebooting the platform, because the power mux is a break-before-make connection.
The power mux passes the selected output onto the +VIN_CHRG bus, which is routed to the PMIC device, EU2. The battery management features of EU2 are not supported. See Battery Path for details.
Voltage regulators and load switches on the expansion board provide the necessary supplies for various devices and interfaces of the board to function.

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
