The ConnectCore 8X System-on-Module

NXP i.MX 8X application processor

The ConnectCore 8X System-on-Module
This section describes the functionality of the ConnectCore 8X System-on-Module.

Power interfaces

System-on-Module input power supply

The ConnectCore 8X requires three primary power supply inputs: VSYS, VSYS2, and VCC_MCA:
VSYS and VSYS2 are the input power supplies to the on-module NXP PF8100 Power
n
Management IC (PMIC), as well as to most of its regulators. Some of the PMIC regulators are
internally dedicated to powering the module, while others power external circuitry.
VCC_MCA is the input power supply of the on-module Micro Controller Assist.
n
Two additional linear dropout regulators, which have a dedicated input power line, are available to
power carrier board external circuitry. These additional regulators are not mandatory.
The following table summarizes the PMIC regulators of the ConnectCore 8X SOM:
