About the Micro Controller Assist

The Micro Controller Assist, or MCA, is a small microcontroller that is deeply integrated into the design
of the ConnectCore 8X module. It assists the i.MX 8X processor with advanced operations related to
power management, security, and system reliability. The functionality provided by the MCA includes:
Advanced power management such as power key button, wake up sources, and PMIC control
n
in low power.
Peripheral extensions such as RTC, watchdog, and tamper pins.

The MCA and the i.MX 8X are connected through an I2C interface and an interrupt line. The
microcontroller provides up to 19 general purpose IOs that can be configured with different modes to
provide functionality such as digital input/output or ADC.
